  There is provided a noble process for producing a salicylic ester for perfumes which comprises the step of transesterifying a salicylic lower alkyl ester with an alcohol having at least one carbon atom which is located adjacent to a hydroxyl-bonded carbon atom and has one or more hydrogen atoms bonded thereto, in the presence of a tin-based catalyst. The process of the present invention enables the salicylic ester to be produced at a high yield and is free from handling problems such as precipitation of solids in a distillation residue obtained after the reaction, and the catalyst used therein is reusable.

  提供了一种用于制备香水中水杨酸酯的高贵过程，包括以下步骤：在锡基催化剂的存在下，将水杨酸较低的烷基酯与至少具有一个碳原子且位于与羟基键合的碳原子相邻的醇反酯化，所述醇具有一个或多个氢原子与之键合。本发明的过程使得水杨酸酯能够以高产率生产，并且不会出现处理问题，例如在反应后得到的蒸馏残渣中固体的沉淀，其中使用的催化剂可重复使用。
