Embodiment Construction
[0014] 1. Preparation process: Accurately weigh a certain mass ratio of stearic acid and sodium stearate into a three-necked flask, and add a certain amount of 1,2-propanediol to completely dissolve it. Then slowly add a certain amount of mixed solution of butyl titanate and ethanol to react at 105°C for 70 minutes, then lower the reaction temperature to 90°C, then add the corresponding quality of sodium persulfate, or cerium oxide, sodium peroxide, Ammonium persulfate and potassium persulfate were continuously stirred and reacted for 2 hours. Cooling device, sample collection.
[0015] The following specific embodiments help to understand the present invention, but do not limit the content of the present invention.
[0016] The percentage (100%) of each component accounting for the total mass of the feed in its specific composition is:
[0017] Scheme 1: 2% butyl titanate, 2% stearic acid, 0.5% sodium stearate, 5% 1,2-propylene glycol, 4% ethanol, and the rest is sodium per...

The invention discloses a method for reducing interfacial tension of a water-soluble inorganic oxidant or a water-soluble inorganic salt in an oil-soluble material, which belongs to the technical fields of new materials and chemical industry. The method comprises the following steps: firstly, dissolving stearic acid and sodium stearate in 1, 2-propylene glycol to form a mixed solution; then, adding butyl titanate and ethanol in the mixed solution, reacting at an environmental temperature of 105 DEG C, cooling the reaction system to 90 DEG C, adding the water-soluble inorganic oxidant or the water-soluble inorganic salt, reacting while stirring, and cooling to obtain the water-soluble inorganic oxidant or water-soluble inorganic salt with reduced interfacial tension. The method disclosed by the invention can effectively reduce the interfacial tension of the water-soluble inorganic oxidant or the water-soluble inorganic salt with the oil-soluble material and improve the encapsulation efficiency of the oil-soluble material on the water-soluble inorganic oxidant or the water-soluble inorganic salt.
Description
technical field [0001] The invention belongs to the technical fields of new materials and chemistry and chemical engineering. Background technique [0002] Water-soluble inorganic oxidants or water-soluble inorganic salts (such as cerium oxide, sodium peroxide, sodium persulfate, ammonium persulfate, potassium persulfate, etc.) are widely used in the manufacture of aniline dyes, oxidative color development of vat dyes, metal surface treatment, Organic synthesis, initiation of polymer polymerization, decolorization and bleaching of oil, washing and deodorization of spoiled yeast, ripening agent of wheat, oil exploitation and other fields. However, the above-mentioned water-soluble inorganic oxidants or water-soluble inorganic salts are extremely unstable at room temperature, for example, they are easily deliquescent and agglomerated by moisture in the air, easily decomposed by heat, and the like. [0003] In order to solve the above-mentioned problems, the technology widely ...
