Abstract
Tin chlorides, SnCl2 and SnCl4.5H2O 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.
摘要
氯化亚锡（SnCl₂）和五水合四氯化锡（SnCl₄·5H₂O）是三碳糖、二羟基丙酮和甘油醛与醇类（甲醇、乙醇和正丁醇）反应生成乳酸酯的优良催化剂，其反应机理涉及丙酮酸醛的中间形成，随后发生酯化反应，而卤化锡能显著促进该反应。
