离子液体催化合成1,3-二元醇或其环状缩醛的方法
摘要：
本发明公开了一种以功能化酸性离子液体为催化剂，催化甲醛与烯烃缩合反应合成1，3-二元醇或其环状缩醛(1，3-二氧六环衍生物)的方法。该方法以功能化酸性离子液体为催化剂，采用甲醛水溶液以及烯烃作为反应物，在较为温和的反应条件下，催化合成1，3-二元醇或其环状缩醛(1，3-二氧六环衍生物)。本发明反应原料易得，催化剂腐蚀性低、催化活性高并可循环使用，产物选择性高，反应过程简便、容易操作、可控性强。
摘要（英）：

The invention discloses a method for synthesizing 1,3-dibasic alcohol or cyclic acetal of 1,3-dibasic alcohol(1,3-dioxane derivative)by using a functional acid ionic liquid serving as a catalyst to catalyze the condensation reaction of formaldehyde and alkene. In the method, the aqueous solution of formaldehyde and the alkene are used as reactants to the 1,3-dibasic alcohol or cyclic acetal of 1,3-dibasic alcohol(1,3-dioxane derivative) under a mild reaction condition in the presence of the functional acid ionic liquid serving as the catalyst. The method has the advantages of readily availablereaction materials, low-corrosivity high-catalytic activity reusable catalyst, high product selectivity, simple reaction process, easy operation and strong controllability.
