摘要: 9,10-二氢-9氧杂-10-膦杂菲-10-氧化物(DOPO)的合成涉及酯化、酰基化、水解和脱水环化反应.通过核磁共振磷谱(31P NMR)对各步反应得到的产物进行表征,分析各反应产物的组成,由此得出各步反应规律,并找出了影响DOPO的产率和纯度的一些关键因素.

Abstract: The synthesis of flame retardant 9,10-dihydro-9-oxa-10-phosphaphen-anthrene-10-oxide (DOPO) involves many steps of chemical reactions, including esterification, Friedel-Crafts acylation, hydrolysis and dehydration. We analyzed the composition of the products from each of the steps with 31P NMR. The results were used to deduce the reaction routes and to optimize the reaction conditions. Based on the results, some key factors that may influence the yield and purity of DOPO were determined.

Key words: 31P NMR, flame retardant, 9,10-dihydro-9-oxa-10-phosphaphen-anthrene-10-oxide (DOPO)
