Abstract
본 발명은 선택적으로 예비가수분해된 알콕시화규소 및 알콕시화티탄(이의 가수분해능은 킬레이트 형성에 의해 감소된다)으로부터 산성 또는 염기성 가수분해 조건하에서 줄을 제조하고, 이 졸을 겔화하고 시효시키고, 이렇게 제조된 시효된 겔을 졸의 제조시 사용된 용매 및 가수분해시 생성된 알콜을 초임계 이산화탄소로 추출함으로써 건조시키고, 필요한 경우, 상기로부터 생성되는 에어로겔을 산소를 함유하는 기체 스트림에서 1000℃이하의 온도에서 하소함으로써 제조가능한 실리카-티타니아 혼합된 산화물 촉매에 관한 것이다. 이러한 촉매는 특히 올레핀성 불포화 화합물의 유기 하이드로퍼옥시드와의 에폭시화를 촉매하는데 사용될 수 있다.
