离子液体作溶剂合成螺环磷酰二氯

Ion Liquid as Solvent to Synthesize SPDPC

摘要:

用离子液体既作溶剂又作催化剂合成了螺环磷酰二氯（SPDPC），原料季戊四醇与三氯氧磷的摩尔比为1:2.2，反应温度40℃，反应时间7h，产率66%。用熔点、IR和1HNMR表征了SPDPC的结构。推测了离子液体的催化机理。合成方法与文献典型的方法做了比较，结果发现，用离子液体作溶剂和催化剂，不但缩短了反应时间，降低了反应温度，而且不挥发，易回收，经济、环保，是合适的合成SPDPC的溶剂和催化剂。

Abstract:

SPDPC was synthesized in Ion Liquid as solvent and catalyst. Pentaerythritol reacted with phosphorus oxychloride in 1:2.2 molar ratio under 40℃ for 7h,the yield is 66%. The structure of SPDPC was characterized by MP, IR and 1HNMR. The catalytic mechanism of Ion Liquid was speculated. The new way was compared with the traditional ones. It is found that Ion Liquid as solvent and catalyst not only shortened the time of reaction and reduced the reactive temperature, but avoided volatilizing, more collectable, economical and environmental friendly as a suitable solvent and catalyst for SPDPC synthesis.
