Abstract

The present invention relates to sodium condensation process for synthesizing phenyl alkoxyl silane. Chlorobenzene and MeaSiXb(OR)4-(a+b), where, X is Cl or Br, R is Me or Et, a is 0 or1 and b is 1, 2, 3 or 4, are made to produce sodium condensation reaction in solvent at 98-130 deg.c for 0.5-8 hr. The process has complete reaction of metal sodium, simple operation, short reaction period, benzene converting rate up to 70-80 %, and MePhSi(OR)2 selectivity up to 50 %.

Description

Technical field

[0001] The present invention relates to the synthesis of phenylalkoxysilane by sodium condensation method. Background technique

[0002] In polymer materials such as silicone oil, silicone rubber, and silicone resin, when the main chain silicon atom has a phenyl group, it can be endowed with excellent high and low temperature resistance, high energy radiation resistance and physical and mechanical properties, and it can also be improved. The compatibility of organic compounds (or polymers) and inorganic fillers increases the refractive index of polysiloxane. When the phenyl-containing polysiloxane matches the refractive index of the selected filler, a transparent material can be obtained. Phenyl-containing alkoxysilane Me a Ph b Si(OR) 4-(a+b) (wherein, a=0 or 1; b=1, 2 or 3; R is Me or Et) (Me is CH 3 -, Et is CH 3 CH 2 -, Ph is C 6 h 5 -, the same below) is the basic monomer for synthesizing phenyl silicone oil, phenyl silicone rubber, and phenyl s...
