A series of sulfonic acid functionalized ionic liquids (SO3H-ILs) have been synthesized, characterized and investigated as catalysts for the conversion of the triose sugars, 1,3-dihydroxyacetone (DHA) and glyceraldehyde (GLA), to pyruvaldehyde dimethylacetal (PADA) in methanol. Depending on the reaction conditions and the applied SO3H-ILs a good yield of up to 52% of PADA was obtained. Under identical
合成,表征和研究了一系列磺酸官能化的离子液体(SO 3 H-ILs),作为将三糖,1,3-二羟基丙酮(DHA)和甘油醛(GLA)转化为丙酮醛二甲基缩醛( PADA)在甲醇中。取决于反应条件和所施加的SO 3 H-IL,获得高达52%的PADA的良好产率。在相同的反应条件下,使用另一种SO 3 H-IL可获得高达49%的PADA衍生物1,1,2,2-四甲氧基丙烷(TMP)。
