Description

Technical Field

[0001] The utility model relates to the technical field of organic silicon monomer preparation, in particular to an organic silicon monomer preparation device. Background Art

[0002] At present, the Grignard synthesis process commonly used at home and abroad to produce silicone monomers has many and complicated process steps; the raw material Grignard reagent is expensive and costly, and is not suitable for large-scale industrial production. Therefore, in the field of organic silica gel, the main silica gel raw materials such as methylsilane monomers and phenylsilane monomers are not synthesized by the Grignard method, but have been replaced by other methods. However, to synthesize special silicone monomers, non-Grignard synthesis is still not possible, which shows that the Grignard synthesis method still has its very important position, and the existing equipment still has some defects; for example;

[0003] For example, the publication number CN103936783B is a device for continuously preparing organic silicon monomers containing special groups and a preparation method using the device. When the technology is used, the organic silicon monomer is synthesized in a one-step method without solvents through the Grignard synthesis principle. The Grignard synthesis method is the most effective method for synthesizing organic silicon monomers. Almost all groups can be connected to silicon atoms using Grignard compounds. If we further consider that these substitution reactions can be carried out once, twice, three times and four times, and the types of organic groups can be different, the Grignard synthesis method can be used to synthesize a large number of organic silane monomers;

[0004] The above-mentioned device has some problems. It is cumbersome to use, and the preparation device is troublesome to use. It cannot be integrated and the treatment effect is poor. The device is not stable during preparation, the degree of automation is low, and the use efficiency is poor.

[0005] Therefore, we propose a device for preparing an organosilicon monomer in order to solve the above-mentioned problems. Utility Model Content
