摘要: 对以1环己氧基4羟基2,2,6,6四甲基哌啶醇(简称CHPOL)和三氯化磷为原料,合成亚磷酸三(1环己氧基2,2,6,6四甲基哌啶基)酯进行了研究,并通过IR、1H NMR、13C NMR和31P NMR表征了其结构。其较佳的合成工艺条件是:氯仿为溶剂,三乙胺为缚酸剂,n(PCl3)∶n(CPOL)∶n(三乙胺)=1∶3∶9,反应时间为8 h,反应温度为30 ℃。在此条件下,产品的摩尔分数为9804%,磷收率为6857%。

Abstract: Tris(1cyclohexyloxy2,2,6,6tetramethyl piperidine4yl)phosphite was synthesized by using 1cyclohexyloxy 2,2,6,6tetramethylpiperidine4ol(referred as CHPOL) and phosphorus trichloride as raw materials,and its structure was characterized by IR, 1H NMR, 13C NMR and 31P NMR.The results revealed that the optimal conditions were: Chloroform as solvent, triethylamine as acidbinding agent,n(PCl3)∶n(CHPOL)∶n(triethylamine)=1∶3∶9, the reaction time being 8 h,and the reaction temperature being 30 ℃.Under the above conditions,the molar content of the products was 9804% and the yield of phosphorus was 6857%.
Key words: 1cyclohexyloxy2,2,6,6tetramethyl piperidine4yl; tris(1cyclohexyloxy2,2,6,6tetramethylpiperidine4yl)phosphite; synthesis
