Embodiment Construction

[0012] 1. Modification process:

[0013] 1. Stir a certain mass ratio of aluminum chloride and deionized water in a three-necked flask until completely dissolved, add a mixture of methanol and propylene glycol of the corresponding mass ratio, heat to reflux, separate methanol, and dry it in vacuum to make intermediate product A spare.

[0014] 2. Accurately weigh a certain amount of oleic acid, n-butanol and n-hexanoic acid and mix them in a three-necked reaction flask, add a certain amount of titanium sulfate, and after 1.5 hours of reaction, add a certain amount of intermediate product A and stir. Add quantitative sodium persulfate (or cerium oxide, sodium peroxide, ammonium persulfate, potassium persulfate) to continue the reaction for 2 hours. Cool, stand still, separate and dry to get the product.

[0015] The percentage (100%) of each component accounting for the total weight of the feed in its specific composition is:

[0016] Scheme 1: 3% aluminum chloride, 3% metha...

Abstract

The invention discloses a method for carrying out oleophylic and hydrophobic modification on the surface of a water-soluble inorganic oxidant or inorganic salt, and belongs to the fields of materials, chemistry and chemical technology. The method comprises the following steps: firstly, adding methanol and propylene glycol into a deionized water solution of aluminium chloride, heating the obtained mixture until a reflux is formed, and after methanol is separated, carrying out vacuum drying on the obtained object so as to obtain an intermediate product; then, after oleic acid, n-butyl alcohol, n-hexylic acid and titanous sulfate are mixed to react, adding the intermediate product obtained in the step 1), and the water-soluble inorganic oxidant or inorganic salt into the obtained mixture to continue to react, after the reaction is completed, cooling the obtained object to room temperature, standing and separating the obtained object so as to obtain a solid phase, and then, drying the solid phase so as to obtain a modified water-soluble inorganic oxidant or inorganic salt. The method is adopted for carrying out oleophylic and hydrophobic modification on the surface of the water-soluble inorganic oxidant or inorganic salt, so that the storage stability of the water-soluble inorganic oxidant or inorganic salt in moist air and the particle dispersity of the water-soluble inorganic oxidant or inorganic salt in solutions are improved, therefore, the universality of the water-soluble inorganic oxidant or inorganic salt in industrialized applications can be further improved.

Description

technical field [0001] The invention belongs to the technical field of materials, chemistry and chemical engineering. Background technique [0002] Such as cerium oxide, sodium peroxide, sodium persulfate, ammonium persulfate, potassium persulfate and other water-soluble inorganic oxidants or inorganic salts have strong oxidizing and corrosive properties, and they can be used as free initiators in polymer polymerization reactions (such as Emulsion polymerization and redox polymerization in the polymerization of vinyl chloride compounds), used as a bleaching agent in the oil and soap industry, and widely used in the dye industry, electroplating industry, photographic industry and chemical engineering. However, they also have some disadvantages in use, such as being easily soluble in water, having a high solubility in water, being easily hydrolyzed or decomposed when encountering water, and easy to be damp and agglomerated in humid air. This affects the further widespread...
