摘要： 采用浸渍法制备了羟基磷灰石 (HAP) 负载的路易斯酸 SnCl2 和 SnCl4 催化剂. 它们在三糖在醇溶液中转化为乳酸酯反应中表现出一定的催化活性. 在最佳的反应条件下, SnCl2/HAP 催化 1,3-二羟丙酮在正丁醇溶液中转化为乳酸正丁酯, 收率高达 73.5%.

Abstract: We prepared hydroxyapatite-supported tin(II) chloride and tin(IV) chloride Lewis acid catalysts. These catalysts showed catalytic activity for the transformation of trioses in alcohols to yield alkyl lactates. Under optimal conditions, n-butyl lactate was obtained in 73.5% yield when dihydroxyacetone and n-butanol were treated with hydroxyapatite-supported tin(II) chloride.

Key words: triose, hydroxyapatite, alkyl lactate, tin(II) chloride, solid catalyst
