环氧碘丙烷合成方法的改进

AN IMPROVED METHOD OF SYNTHESIS OF EPIIODOHYDRIN

本文报导一种合成环氧碘丙烷的改进方法。用环氧氯丙烷直接与碘化钾饱和水溶液在75℃下反应一小时,环氧碘丙烷的收率可达80—96%。还研究了反应物用量此、反应温度和反应时间等对产率的影响,并测定了卤代环氧丙烷对苦味酸钾的络合能力。

In this paper we report an improved method of synthesis of epiiodohy-drin.The epiiodohydrin was prepared with yield 80-96%via the reaction of epichlorohydrin with KI in saturated aqueous solution at 75℃for 1 hr.The influence of some factors,such as raw materials ratio,reaction time and temperature,on the yield in this reaction and the complexing properties of epihalohydrins with potassium picrate have also been investigated.
