A process for the conversion of an alkylene oxide to the corresponding alkylene glycol in the presence of carbon dioxide, water and a catalytic composition comprising a mixture of an organic base present in an amount in the range of from 10 to 90 mol % (based on the mixture) and a salt of the organic base and a hydrogen halide the salt being present in an amount in the range of from 10 to 90 mol % (based on the mixture), wherein the organic base comprises a carbon-based compound comprising one or more nitrogen atoms with at least one free electron pair and/or one or more phosphorous atoms with at least one free electron pair, and has a pKa high enough that it is capable of binding carbon dioxide under the reaction conditions.
在碳酸气体、水和催化组分的存在下,将烯丙基氧化物转化为相应的烯丙基二醇的过程,所述催化组分包括有机碱和有机碱的氢卤酸盐的混合物,其中有机碱在混合物中的含量范围为10至90摩尔%,盐在混合物中的含量范围为10至90摩尔%,所述有机碱包括一种碳基化合物,其包含一个或多个氮原子和/或一个或多个磷原子,具有至少一个自由电子对,并且具有足够高的pKa,以便在反应条件下能够结合碳酸气体。
