Abstract

본 발명은 특정의 물성을 갖는 몬모릴로나아트 점토 촉매의 존재하에서 올레핀을 황화수소와 반응시켜 간단하게 고수율로 목적하는 알킬머갑탄을 제조하는 개선된 방법에 관한 것이다. 본 발명에서 사용되는 몬모릴로나이트 점토 촉매는 산도가 6 이상이며, 입자가 20메쉬 내지 60메쉬의 입자크기를 갖는 촉매로서, 예를 들면 필트롤(Filrton) 24 및 삼화백토 샤크니트(Shacnit) #136등이 있다. 이러한 특정의 촉매를 사용함으로써 온화한 반응조건에서 부산물이 없 85% 이상의 고수율로 목적물을 제조할 수 있을 뿐 아니라 본 발명에서 이용된 촉매를 촉매의 수명이 길고 재생에도 용이하여 경제적으라는 잇점도 제공한다.The present invention is directed to an improved process for the preparation of the desired alkylmergartan in high yields simply by reacting olefins with hydrogen sulfide in the presence of montmorillonaart clay catalysts having certain physical properties. The montmorillonite clay catalyst used in the present invention is a catalyst having an acidity of 6 or more and particles having a particle size of 20 mesh to 60 mesh, for example, Filtton 24 and Shatrinit Shacnit # 136. There is this. By using such a specific catalyst, not only by-products can be produced in a high yield of more than 85% under mild reaction conditions, but also provide the advantage that the catalyst used in the present invention has a long life and easy regeneration of the catalyst and is economical. .
