Device for continuously preparing organic silicon monomer containing special group and preparation method using device

Abstract

The invention discloses a device for continuously preparing an organic silicon monomer containing special groups and a preparation method using the device. The preparation method of the organic silicon monomer containing the special groups is adopted for synthesizing the organic silicon monomer by using a Grignard synthesis principle and a non-catalytic one-step method. The Grignard synthesis principle is a most effect synthesis method for synthesizing the organic silicon monomer, and almost various groups can be connected to silicon atoms by using Grignard compounds. Based on the consideration that the substitution reaction can be performed for once, twice, three times and four times, and the organic groups can be different, multiple organic silicon monomers can be synthesized by using a Grignard synthesis method, and the device is particularly significant for organic silicon monomers which cannot be synthesized by using other methods and which contains the special groups.

Description

Technical field [0001] The invention belongs to the technical field of preparation of chemical raw materials, and specifically relates to a device for continuously preparing organosilicon monomers containing special groups and a preparation method using the device. Background technique [0002] At present, the Grignard synthesis process commonly used at home and abroad to produce organosilicon monomers has its advantages and disadvantages as follows. The advantage is that the product has fewer components and can remove most of the alkyl, aryl, and unsaturated groups (ene Types, alkynes), etc. are introduced into silicon atoms to prepare special organosilicon monomers. Mixed hydrocarbyl silanes with different organic groups attached to a silicon atom can also be prepared, which can by-produce metal salts; the disadvantage is: reaction When using a large amount of flammable ether or other solvents, not only the consumption is large, but also flammable and explosive, and the product...

[0002] At present, the Grignard synthesis method commonly used at home and abroad to produce organosilicon monomers has advantages and disadvantages as follows. Classes, alkynes) etc. are introduced onto silicon atoms to prepare special organosilicon monomers, and mixed hydrocarbyl silanes with different organic groups attached to one silicon atom can also be produced, which can by-produce metal salts; the disadvantage is: the reaction When it is necessary to use a large amount of flammable ether or other solvents, not only the consumption is large, but also flammable and explosive, and the production is unsafe;
