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)=13∶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
