Abstract
본 발명은 안정제 또는 산화방지제로 널리 사용되는 다음 일반식(I)의 트리아릴포스파이트의 제조방법에 관한 것으로, 삼할로겐화인과 일반식(B) 화합물을 반응시켜서 제조함에 있어서 반응촉매로서 트리에틸렌디아민 또는 일반식(II)은 화합물에서 선택된 촉매를 사용하고, 반응중 생성되는 HCI 가스를 질소로 폭기(Bubbling)시킴을 특징으로 하는 새로운 방법을 제공하는 것이다.The present invention relates to a method for preparing triaryl phosphite of the following general formula (I), which is widely used as a stabilizer or an antioxidant. Diamine or general formula (II) is to provide a new process characterized by using a catalyst selected from compounds and aeration of the HCI gas produced during the reaction with nitrogen.
상기식에서, X는 아릴기 또는, 직쇄 또는 가지를 가진 알킬기, 사이클로알킬기, 아릴알킬기의 1종 이상의 기로 치환된 알릴기를 나타내며, R은 메틸 또는 에틸기이며, n은 1에서 6의 정수를 나타낸다.Wherein X represents an aryl group or an allyl group substituted with one or more groups of an alkyl group, a cycloalkyl group, an arylalkyl group having a straight or branched chain, R is a methyl or ethyl group, and n represents an integer of 1 to 6.
본 발명의 방법에 의하여 보다 간편한 공정으로 고수율로, 보다 양호한 특성의 트리알킬포스파이트를 제조할 수 있다By the process of the present invention, trialkyl phosphite of better properties can be produced in a higher yield in a simpler process.
