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%.
採用浸漬法製備瞭羥基燐灰石(HAP)負載的路易斯痠SnCl2和SnCl4催化劑.它們在三糖在醇溶液中轉化為乳痠酯反應中錶現齣一定的催化活性.在最佳的反應條件下,SnCl2/HAP催化1,3-二羥丙酮在正丁醇溶液中轉化為乳痠正丁酯,收率高達73.5%.

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.
