Abstract

The present invention relates to the field of chemical engineering, and specifically relates to a preparation method of a modified-methyl tributylketoxime silane extraction and separation aid. The 120# solvent oil extraction system of methyl ethyl ketoxime silane, using the extraction and separation aid of the present invention can prevent the distribution coefficient from jumping with the concentration increase, which is conducive to the stability and continuity of the extraction operation, while ensuring that the 120# solvent When the oil composition changes, the continuous production of the modified-methyltributanoximinosilane finished product can be ensured smoothly. The extraction and separation aid of the invention can accelerate the separation of the extraction agent and butanone oxime hydrochloride, increase the extraction efficiency, speed up the process, and ensure the stability and high efficiency of the process.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for preparing a modified-methyl tributylketoxime silane extraction and separation aid. Background technique [0002] Modified-methyl tributylketoxime silane is a kind of crosslinking agent with better reactivity prepared by the reaction of butanone oxime, methyltrichlorosilane and silicon tetrachloride mixture. The extraction operation is to produce essential steps in the process. [0003] CN110981902A is about a kind of preparation method of modified monomethyl tributyl ketoxime base silane; A kind of preparation method of modified monomethyl tributyl ketoxime base silane of the present invention, this method provides a kind of by butanone oxime and A method for preparing modified monomethyltributanone oximinosilane by reacting a mixed solution of methyltrichlorosilane and silicon tetrachloride. In this method, a certain proportion of silicon tetrachloride is used as a...
