Abstract
A method for preparing alkyldichlorosilanes having a Si—H bond by directly reacting metallic silicon with a mixture of alkyl chloride and hydrogen chloride or alkyl chloride which generates hydrogen chloride at a reaction temperature in the presence of copper catalyst.
Claims6
A method for preparing alkyidichlorosilanes of Formula 3 by directly reacting metallic silicon with a mixture of alkyl chloride of Formula 1 and hydrogen chloride or alkyl chloride (Formula 2) which can generate hydrogen chloride at a reaction temperature in the presence of copper catalyst:
- 1 RCl ( Formula 1 ) + R 1 Cl ( Formula 2 ) → RSiHCl 2 ( Formula 3 ) + RSiCl 3 ( Formula 4 ) Formula 1
- wherein, R is a linear, branched or cyclic C3-10 alkyl group, R1 is hydrogen or a first, secondary or tertiary C4-6 alkyl group.
