Description
Claims (8)
- 규소 및 구리 촉매를 포함하는 접촉 조성물(contact composition)과 클로로메탄을 반응시켜 메틸클로로실란을 직접 합성하는 방법으로서,사용되는 클로로메탄 중 산소의 농도가(a) 산소를 함유하는 클로로메탄 및(b) 기체상 붕소 화합물을 함유하는 클로로메탄의 혼합에 의해 감소되는 것인 방법.
- 제1항에 있어서, 연속적으로 수행되는 것인 방법.
- 제1항 또는 제2항에 있어서, 직접 합성 후에 반응기로부터 방출되는 생성물 혼합물 중에 존재하는 휘발성 붕소 화합물이 완전히 제거되지 않으며, 클로로메탄을 포함하는 생성된 기체 혼합물이 클로로메탄 (b)로서 사용되는 것인 방법.
- 제1항 또는 제2항에 있어서, 클로로메탄 (a) : 클로로메탄 (b)의 혼합비가 20:80 ~ 80:20인 방법.
- 제1항 또는 제2항에 있어서, 상기 클로로메탄 (b) 중 휘발성 붕소 화합물의 농도는 적어도 50 부피ppm인 방법.
- 제1항 또는 제2항에 있어서, 상기 클로로메탄 (b)는 추가로 메틸클로로모노실란을 함유하는 것인 방법.
- 제6항에 있어서, 상기 클로로메탄 (b)는 0.10 MPa 및 20℃에서 m3당 적어도 5 mg의 메틸클로로모노실란을 함유하는 것인 방법.
