Problems solved by technology

Sodium diisooctyl sulfonate maleate is more and more widely used, and the amount of use is increasing year by year. However, sodium diisooctyl sulfonate maleate is prone to produce a lot of foam during use. In addition, maleic acid The traditional production process of diisooctyl sodium sulfonate has defects: in the existing process, the catalyst must be neutralized and washed with alkali, and washing with water not only causes pollution, but also reduces the yield and increases the cost

Embodiment 1

[0021] Solid Superacid S 2 O 8 2- / ZrO 2 Preparation of Catalyst 1

[0022] Pour 1000ml of zirconium oxychloride solution with a concentration of 0.6 mol / L into a 2000ml four-necked glass flask, stir and dropwise add 25% ammonia solution to adjust the pH value to 9, control the temperature below 20°C, precipitate and age for 36h, pump filtered, washed to be free of Cl - Detected, then dried at 105°C for 24 hours, ground to below 100 mesh, and set aside. Use 554 mL of ammonium persulfate solution with a concentration of 2.0 mol / L to impregnate the sample for a certain period of time, filter, dry at 105°C for 12 hours, and roast at 600°C for 6 hours to obtain solid superacid S 2 o 8 2- / ZrO 2 Catalyst, spare.

Embodiment 2

[0024] Solid Superacid S 2 O 8 2- / ZrO 2 Preparation of Catalyst 2

[0025] Pour 1000ml of zirconium oxychloride solution with a concentration of 1.0 mol / L into a 2000ml four-neck glass flask, stir and dropwise add 25% ammonia solution to adjust the pH value to 11, control the temperature below 20°C, precipitate and age for 12 hours, pump filtered, washed to be free of Cl - Detected, then dried at 105°C for 24 hours, ground to below 100 mesh, and set aside. Use 1476mL ammonium persulfate solution with a concentration of 1.25mol / L to impregnate the sample for a certain period of time, filter, dry at 105°C for 12h, and roast at 800°C for 2h to obtain solid superacid S 2 o 8 2- / ZrO 2 Catalyst, spare.

Embodiment 3

[0027] Solid Superacid S 2 O 8 2- / ZrO 2 Preparation of Catalyst 3

[0028] Pour 1000ml of zirconium oxychloride solution with a concentration of 0.2 mol / L into a 2000ml four-neck glass flask, stir and add 25% ammonia solution dropwise to adjust the pH value to 10, control the temperature below 20°C, precipitate and age for 24 hours, pump filtered, washed to be free of Cl - Detected, then dried at 105°C for 24 hours, ground to below 100 mesh, and set aside. Use 738mL ammonium persulfate solution with a concentration of 0.5mol / L to impregnate the sample for a certain period of time, filter, dry at 105°C for 12h, and roast at 400°C for 4h to obtain solid superacid S 2 o 8 2- / ZrO 2 Catalyst, spare.

Abstract

The invention discloses a preparation method of isooctanol polyoxypropylene ether sodium sulfosuccinate diester. The method comprises the following steps of: adding epoxy propane into isooctanol serving as an initiator under the action of a modified DMC (Di Methyl Carbonate) catalyst for undergoing a condensation reaction to obtain isooctanol polyoxypropylene ether; undergoing an esterification reaction on the isooctanol polyoxypropylene ether and maleic anhydride under the catalytic action of a solid super acid S2O8<2-> / ZrO2 to obtain isooctanol polyoxypropylene ether sulfosuccinate diester; and undergoing a sulfonation reaction on the isooctanol polyoxypropylene ether sulfosuccinate diester and a sodium metabisulfite solution under the action of a phase transfer catalyst, and adding a NaOH aqueous solution till the pH of a reactant is 4-7 to obtain the isooctanol polyoxypropylene ether sodium sulfosuccinate diester. The preparation method has the advantages of clean, environmentally-friendly and simple production process, higher permeability and remarkable reduction in foams produced in the using process.

Description

technical field [0001] The invention relates to a preparation method of isooctyl alcohol polyoxypropylene ether succinic acid diester sodium sulfonate. It belongs to the technical field of synthesis of anionic surfactants in organic chemistry. Background technique [0002] Sodium diisooctyl sulfonate maleate (Sodium isooctyl succinate diester sulfonate, commonly known as fast penetrating agent T) is mainly used in petrochemical, pesticide, light industry, medicine, metallurgy, textile, printing and dyeing, papermaking , tanning and other industries, especially in the textile industry to deal with cotton, linen, viscose and blended products, the treated fabric can be directly bleached and dyed without scouring, improving the dyeing defects caused by dead cotton, and the fabric feel after printing and dyeing Softer, fuller and can be used as an emulsifier, dispersant or stabilizer. Sodium diisooctyl sulfonate maleate is more and more widely used, and the amount of use is inc...
