Description

Technical Field

[0001] The invention relates to the technical field of chemistry and chemical engineering, in particular to a multifunctional emulsifying compound. Background Art

[0002] The current emulsifier compounds available on the market have the problems of single applicability and strong functional limitations. Existing products are usually designed for specific base materials, lack versatility, and are difficult to be compatible with diverse base materials such as mineral oils and plasticizers. This makes it difficult to achieve a balance between oil solubility and water solubility, and limits emulsification efficiency and stability. For example, although some emulsifiers have good oil solubility, they have poor water solubility and cannot meet the needs of complex formulations; and emulsifiers with single functions have difficulty solving compatibility problems in multi-component systems, resulting in the emulsified products produced being prone to stratification and poor stability. In addition, traditional emulsifiers are highly dependent on the type of base oil and cannot adapt to the compatibility requirements of materials such as mineral oils and plasticizers commonly found in the market, further limiting their application scenarios.

[0003] To address this industry pain point, this invention aims to develop a multifunctional emulsifying compound. By combining synergistic components, this compound overcomes the compatibility limitations of traditional emulsifiers, achieving broad compatibility with a wide range of base oils, including mineral oils and plasticizers, while also enhancing the water solubility and long-term stability of the emulsion. This compound significantly improves the compatibility of emulsions with tap water, resolving the stratification issue and providing a universal solution for multiple applications (such as lubricants, plastics processing, and daily chemicals), filling a technological gap in the market.

[0019] See also Figure 1 , a multifunctional emulsifying compound, comprising the following steps: Step 1, raw material preparation: fatty alcohol polyoxyethylene ether MO3-B, sorbitol monooleate, refined petroleum sodium sulfonate, NP-7 alkylphenol polyoxyethylene ether, NP-10 alkylphenol polyoxyethylene ether, dicyclohexylamine, NN-methylenebismorpholine and palmitolamide are selected as raw materials; Step 2: Pretreatment of raw materials: Refining sodium petroleum sulfonate, drying fatty alcohol polyoxyethylene ether MO3-B, sorbitol monooleate, NP-7 alkylphenol polyoxyethylene ether, and NP-10 alkylphenol polyoxyethylene ether, and then grinding dicyclohexylamine, NN-methylenebismorpholine, and palmitolamide; Step 3: Mixing and stirring: adding refined petroleum sodium sulfonate, dried fatty alcohol polyoxyethylene ether MO3-B, sorbitol monooleate, NP-7 alkylphenol polyoxyethylene ether, NP-10 alkylphenol polyoxyethylene ether, dicyclohexylamine, NN-methylenebismorpholine and palmitolamide into a reaction kettle according to the formula ratio to fully mix the raw materials; Step 4: Heating and dissolving: Heat the stirred mixture and maintain constant temperature stirring to completely dissolve the solid raw materials and form a uniform liquid mixture. The temperature should be closely monitored during the heating process to avoid local overheating that may cause decomposition or deterioration of the raw materials. Step 5: Cooling: Cool the heated and dissolved mixture to room temperature using a water bath. Step 6: Homogenization: When the temperature of the mixture drops below 40°C, use a homogenizer to homogenize the mixture. Homogenization can further refine the particles of the mixture and improve its dispersibility and stability. Step 7. Packaging: Filter the homogenized mixture through a filter to remove possible impurities or undissolved particles to obtain an emulsified compound. The filtered emulsified compound is aseptically packaged. The packaging material should have good sealing and moisture-proof properties. The packaged compound is stored in a cool, dry, and ventilated warehouse, avoiding direct sunlight and high temperature environment to ensure its quality and performance.

[0020] Specifically, the raw materials in step 1 and their weight parts are: 6-9 parts of fatty alcohol polyoxyethylene ether MO3-B (MO3 is flocculent and not easy to use in winter); 14-17 parts of sorbitol monooleate; 18-21 parts of sodium petroleum sulfonate (molecular weight 480, refined rust inhibitor); 4-7 parts of NP-7 alkylphenol polyoxyethylene ether (n is 7, emulsifier); 1-3 parts of NP-10 alkylphenol polyoxyethylene ether (n is 10, emulsifier); 2-5 parts of dicyclohexylamine (rust inhibitor, alkalinity stabilizer); 1-4 parts of NN-methylenebismorpholine (with bactericidal function and good antiseptic properties); 1-3 parts of palmitolamide (emulsifier, rust inhibitor, emulsion thickener).

[0021] The raw materials and their functions are shown in Table 1: Table 1 Specifically, the refining process of petroleum sulfonic acid is: S2.1. Raw material preparation: Prepare industrial-grade petroleum sulfonic acid (containing impurities) and 30% to 35% sodium hydroxide solution (concentrated lye) as raw materials; S2.2 Neutralization reaction: Add petroleum sulfonic acid to a reactor and add sodium hydroxide solution dropwise while stirring. Control the reaction temperature to 55-60°C to ensure sufficient reaction. Detect the reaction endpoint using pH test paper. The reaction is complete when the pH value of the solution reaches a neutral pH of 7-8. S2.3, Filtration and Washing: After the reaction is completed, the reaction mixture is cooled to room temperature, filtered to remove insoluble impurities, and the filter cake is washed 2 to 4 times with deionized water to remove residual impurities and unreacted sodium hydroxide; S2.4 Drying: Place the washed sodium petroleum sulfonate filter cake in a drying oven and dry it at 65-70°C for 45-60 minutes. The dried sodium petroleum sulfonate should be a white solid with good fluidity. S2.5. Quality testing: The refined sodium petroleum sulfonate is subjected to quality testing for purity, acid value and moisture content to ensure that it meets the requirements for use in emulsifying compound.

[0022] Specifically, sodium petroleum sulfonate is produced by the reaction of petroleum sulfonic acid and sodium hydroxide, and the reaction formula is: R-SO3H+NaOH→R-SO3Na+H2O In the formula, petroleum sulfonic acid (R-SO3H) reacts with sodium hydroxide (NaOH) to produce sodium petroleum sulfonate (R-SO3Na) and water (H2O), and R represents a hydrocarbon group (such as an alkyl group or an aryl group); Specifically, in the raw material pretreatment process in step 2: fatty alcohol polyoxyethylene ether MO3-B, sorbitol monooleate, NP-7 alkylphenol polyoxyethylene ether, and NP-10 alkylphenol polyoxyethylene ether are dried separately to remove surface adsorbed moisture, the drying temperature is controlled at 40-50°C, and the drying time is 2-3 hours.

[0023] Specifically, in the raw material pretreatment process in step 2, dicyclohexylamine, NN-methylenebismorpholine and palmitolamide are ground and crushed respectively, and passed through a 100-200 mesh sieve to make the particle size uniform for the subsequent mixing reaction.

[0024] The advantages are: the present invention prepares fatty alcohol polyoxyethylene ether MO3-B and sodium petroleum sulfonate according to specific weight parts, wherein MO3-B and sodium petroleum sulfonate form a complementary hydrophilic-lipophilic balance system, thereby improving emulsification stability; and adopts water bath cooling and homogenization processes in the preparation process to ensure that the various components are fully reacted and dispersed, thereby achieving excellent stability effect. The emulsion product prepared by using the composite agent has high solubility in tap water, and the emulsion can maintain long-term stability without stratification, thereby effectively improving the quality and service life of the emulsion product.

[0025] Specifically, the mixing and stirring conditions in step 3 are: stirring at a speed of 300-500 rpm for 30-45 minutes, and the temperature is controlled between 45-50° C. during the stirring process.

[0026] Specifically, the cooling process in step 5 is as follows: the reactor is placed in a cold water bath to remove heat through water circulation, so that the mixture is cooled rapidly. The water bath temperature is controlled at 5-15°C. During the cooling process, the stirring speed is maintained at 100-200 rpm to ensure that the temperature of the mixture drops evenly. After cooling to room temperature, stirring is stopped and the mixture is removed from the water bath.

[0027] Specifically, in step six, the homogenization process is as follows: when the temperature of the mixture drops to 30-40°C, the mixture is homogenized using a homogenizer, the homogenization pressure is controlled at 10-15 MPa, and the homogenization time is 10-15 minutes. The homogenization process can further refine the particles of the mixture and improve its dispersibility and stability.

[0028] The advantages are: by adding dicyclohexylamine, NN-methylenebismorpholine and sodium petroleum sulfonate, a multifunctional system with rust prevention, sterilization and stable alkalinity is constructed. Dicyclohexylamine adjusts the alkalinity to enhance rust prevention, NN-methylenebismorpholine provides efficient sterilization and anti-corrosion functions, and sodium petroleum sulfonate assists in rust prevention and improves overall performance. Combined with precise raw material pretreatment and reaction condition control, an excellent rust and corrosion prevention effect is achieved. The composite agent not only has good rust prevention performance and extends the service life of metal products, but also can achieve sterilization and anti-corrosion functions through NN-methylenebismorpholine, ensuring the quality and safety of the emulsified product during storage and use.

[0033] Examples 1-4 were prepared according to the preparation steps of the present invention to obtain composite agents.

[0034] Comparative Example 1 The raw materials and their weight parts are: 7 parts of fatty alcohol polyoxyethylene ether MO3-B; 16 parts of sorbitol monooleate; 20 parts of sodium petroleum sulfonate; 6 parts of NP-7 alkylphenol polyoxyethylene ether; 2 parts of NP-10 alkylphenol polyoxyethylene ether; 4 parts of dicyclohexylamine; and 2 parts of palmitolamide. Compared with Example 1, the NN-methylenebismorpholine component is removed, and the composite agent is prepared according to the same preparation steps.

[0035] Comparative Example 2 The raw materials and their weight parts are: 9 parts fatty alcohol polyoxyethylene ether MO3-B; 17 parts sorbitol monooleate; 18 parts sodium petroleum sulfonate; 5 parts NP-7 alkylphenol polyoxyethylene ether; 2 parts NP-10 alkylphenol polyoxyethylene ether; 5 parts dicyclohexylamine; 4 parts NN-methylenebismorpholine; and 3 parts palmitolamide. Compared with Example 2, the amount of fatty alcohol polyoxyethylene ether MO3-B was reduced to 3 parts, while the other steps remained unchanged to prepare a composite agent.

[0036] Comparative Example 3 The raw materials and their weight parts are: 14 parts of sorbitol monooleate; 21 parts of sodium petroleum sulfonate; 4 parts of NP-7 alkylphenol polyoxyethylene ether; 1 part of NP-10 alkylphenol polyoxyethylene ether; 2 parts of dicyclohexylamine; 1 part of NN-methylenebismorpholine; and 1 part of palmitolamide. Compared with Example 3, the fatty alcohol polyoxyethylene ether MO3-B component is removed, and the composite agent is prepared according to the steps.

[0037] Comparative Example 4 The raw materials and their weight parts are: 8 parts of fatty alcohol polyoxyethylene ether MO3-B; 15 parts of sorbitol monooleate; 19 parts of sodium petroleum sulfonate; 7 parts of NP-7 alkylphenol polyoxyethylene ether; 3 parts of NP-10 alkylphenol polyoxyethylene ether; 3 parts of dicyclohexylamine; 2 parts of NN-methylenebismorpholine; and 2 parts of palmitolamide. Compared with Example 4, the amount of sodium petroleum sulfonate is reduced to 10 parts, and the remaining operations are the same to prepare a composite agent.

[0038] Examples 1-4 and Comparative Examples 1-4 were prepared into composites and subjected to performance tests. The test data were as follows: Table 2 From the analysis of Table 2, we can get: 1. The rust resistance of Examples 1-4 is better than 45h, indicating that the components in the formula have a good synergistic effect. The rust resistance of Comparative Example 1 (lacking NN-methylenebismorpholine) is greatly reduced (30h), indicating that the fungicide can increase the rust resistance. The rust resistance of Comparative Example 4 (reduced sodium petroleum sulfonate) decreases to 42h, indicating that the sodium petroleum sulfonate content can also increase the rust resistance.

[0039] 2. The stability of the embodiments is ≥90%, while the stability of the comparative examples is reduced due to formulation or process defects (such as reduced MO3-B or lack of MO3-B). Among them, the stability of comparative example 3 (lack of MO3-B) is only 80%, indicating that fatty alcohol polyoxyethylene ether MO3-B can increase the stability of the composite agent.

[0040] 3. The pH values ​​of the examples are all between 7.1 and 7.5, which meet the neutrality requirement. The pH value of Comparative Example 1 (lacking NN-methylenebismorpholine) is relatively low (6.8), indicating that the lack of NN-methylenebismorpholine will affect the rust resistance and stability.

[0041] 4. The bactericidal rates in the examples were all ≥98.8%. The bactericidal rate in Comparative Example 1 (lack of bactericide) dropped significantly to 95.0%. The bactericidal rate in Comparative Example 4 (reduction of sodium petroleum sulfonate) also dropped slightly, indicating that sodium petroleum sulfonate has an auxiliary effect on bactericidal properties.

[0042] 5. The dispersibility of the examples is "excellent" or "good", while the dispersibility of comparative example 3 (lacking MO3-B) is poor, indicating that fatty alcohol polyoxyethylene ether MO3-B can improve the dispersibility of the composite agent.

[0043] Summary: The formulas of Examples 1-4 are complete and the processes are reasonable, and they exhibit excellent performance, among which the comprehensive performance of Example 1 is particularly outstanding. However, due to the lack of NN-methylenebismorpholine, MO3-B or sodium petroleum sulfonate in Comparative Examples 1-4, the rust resistance, stability or bactericidal rate of the composite agent is greatly reduced. Therefore, the lack of fatty alcohol polyoxyethylene ether MO3-B, sodium petroleum sulfonate and NN-methylenebismorpholine will affect the overall performance of the composite agent. Therefore, the formula and preparation process parameters of the embodiments of the present invention can ensure that the overall performance of the composite agent is improved, and Example 1 has the best comprehensive performance.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
