Abstract

조 아세토니트릴, 강염기 및 알데히드를 함께 혼합하고, 혼합물을 환류 온도로 가열하여 조 아세토니트릴을 안정화하고 안정화된 아세토니틀릴을 회수하는 것으로 구성되는 안정화된 조 아세토니트릴(즉, 증기화시 아세토니트릴의 중합이 실질적으로 발생되지 않도록 처리된 아세토니트릴)의 제조 방법. 이 안정화된 아세토니트릴을 시안화 수소를 제조하는데 이용한다.Stabilized crude acetonitrile (ie, vaporization of acetonitrile upon vaporization) consisting of mixing together acetonitrile, strong bases and aldehydes and heating the mixture to reflux to stabilize the crude acetonitrile and recover the stabilized acetonitrile. Acetonitrile), wherein the acetonitrile is treated so that polymerization does not occur substantially. This stabilized acetonitrile is used to produce hydrogen cyanide.
