Problems solved by technology

[0002] Zinc laurate is widely used in plastics, coatings, grease, textiles, construction, papermaking, pigments, daily chemicals and other fields. There are many synthesis methods of zinc laurate, but at present it is mainly saponification reaction and metathesis reaction. In the metathesis method , mainly using lauric acid, zinc chloride and sodium oxide to react, but its yield and quality are not up to the requirements

Embodiment 1

[0007] Add lauric acid and zinc oxide into the reaction vessel, the molar ratio of lauric acid and zinc oxide is about 2:1, add catalyst and dispersant.

[0008] After the reaction, zinc laurate was purified, and the reaction found that the molar ratio of zinc laurate to zinc oxide was close to 1:1.

Abstract

An application of zinc oxide in the preparation of zinc laurate. The present invention changes the use of sodium hydroxide and zinc chloride in the original zinc laurate reaction to zinc oxide. The production capacity of the reaction is greatly improved, and the reaction of lauric acid is more fully, thereby eliminating the bromine smell of lauric acid.

Description

technical field [0001] The present invention relates to the field of chemical synthesis, and more specifically, relates to an application of zinc oxide in the preparation of zinc laurate. Background technique [0002] Zinc laurate is widely used in plastics, coatings, grease, textiles, construction, papermaking, pigments, daily chemicals and other fields. There are many synthesis methods of zinc laurate, but at present it is mainly saponification reaction and metathesis reaction. In the metathesis method , mainly use lauric acid, zinc chloride and sodium oxide to react, but its yield and quality are not up to the requirements. Contents of the invention [0003] The present invention thinks, in the reaction of zinc laurate, intermediate product sodium laurate gelatinization energy is big, and solubility in water is little, and solution is viscous, easily wraps zinc chloride, causes the product and the quality of zinc laurate to fail to meet requirements.
