Patent ID: 8278472

Claim:
A method of preparing allylchlorosilane represented by Formula 1, the method comprising: mixing the allylchlorideallyl chloride derivative and the hydrosilane derivative in a liquid or gaseous phase; adding the mixture into a reactor; and reacting an allylchloride derivative represented by Formula 2 with a hydrosilane derivative represented by Formula 3 at a temperature from 400 to 650° C. and at a pressure of 1 to 3 bar gaseous condition by Si—C coupling reaction: (R 1 R 2 )C═C(R 3 )—CH 2 —Si (X 1 X 2 )—Cl (1) , H—Si (X 1 X 2 )—Cl (2), (R 1 R 2 )C═C(R 3 )—CH 2 —Cl (3), wherein R 1 , R 2 and R 3 , which are same or different, are each independently a hydrogen atom or a methyl group, and X 1 and X 2 , which are same or different, are each independently a hydrogen atom, a chlorine atom, or a methyl group, and the reactants and products stay in the reactor for 2 to 6 seconds.
