氯化锡、SnCl_2和SnCl_4中心点5H（2）O是丙糖、二羟基丙酮和甘油醛与醇（MeOH、EtOH和nBuOH）反应生成乳酸烷基酯的优良催化剂，其反应机理包括中间体乙醛的生成和酯化反应，卤化锡对酯化反应有明显的促进作用。
Tin chlorides, SnCl2 and SnCl4 center dot 5H(2)O are excellent catalysts for the reactions of trioses, dihydroxyacetone and glyceraldehyde with alcohols (MeOH, EtOH and nBuOH) to give alkyl lactates, whose reaction mechanism involves the intermediary formation of pyruvic aldehyde followed by its esterification, which is distinctively promoted by tin halides.
