Octadecyl organic silicon wax and preparation method and application thereof

Abstract

The invention belongs to the field of organic chemical synthesis, and particularly relates to octadecyl organic silicon wax and a preparation method and application thereof. The preparation method of the octadecyl organic silicon wax comprises the following steps: firstly, mixing D4H with hydrogen-terminated silicone oil, reacting under the action of sulfonated cationic resin serving as a catalyst, distilling under a reduced pressure, and filtering to obtain hydrogen-terminated silicone oil of which a side chain contains reactive hydrogen; then, mixing the hydrogen-terminated silicone oil of which the side chain contains the reactive hydrogen with 1-octadecene, performing a silicon-hydrogen addition reaction under the action of chloroplatinic acid serving as a catalyst at the temperature of 90 to 130 DEG C for 6 to 10 hours, and distilling under a reduced pressure after finishing the reaction to obtain the octadecyl organic silicon wax. The invention further provides an organic silicon wax emulsion containing the octadecyl organic silicon wax. The emulsion has the advantages of proper viscosity, high moisture-keeping performance, and high stability.

Description

technical field [0001] The invention belongs to the field of organic chemical synthesis, and in particular relates to an octadecyl silicone wax and its preparation method and application. Background technique [0002] Silicon (Si) is one of the basic elements on the earth and widely exists in nature in the form of compounds. Among them, silicone is mainly used in sealing, surface activity, waterproof, anti-foaming, moisture-proof, inert filling and so on. After years of research and development, the number and varieties of silicones have been increasing, and the application fields have been continuously expanded, forming an important product system in the field of new chemical materials. The excellent performance of many varieties cannot be replaced by other chemicals. [0003] The improvement of people's living standards and the advancement of science and technology have increased the demand for organic silicon materials, and the production and sales of organic silicon at ...

AI Technical Summary

Problems solved by technology

The production technology of organic silicon in my country is relatively backward, and the problems of high cost and low output have been difficult to overcome

However, due to the relatively late start of my country's chemical companies, there is still a significant gap between the research and application level of silicone wax and foreign countries. For example, the production scale of domestic silicone wax products is small, the yield is low, and the process conditions are relatively backward.
