In producing ester compunds useful as an antixidant for organic materials which are reperesented by the formula:
, wherein R¹ and R² are the same or different hydrogen or straight or branched chain alkyl radicals containing 1 - 8 carbon atoms, Z is an organic radical derived from an n-hydroxy alcohol, and n denotes an integer of 1 to 4, by the transesterification, monoalkyltin compounds are used as a catalyst, whereby the ester compounds can be produced with high quality and in high yields.
在生产可用作有机材料抗酸剂的
酯类复合物时,这些复合物由以下式子表示:
其中,R¹ 和 R² 是相同或不同的氢或含有 1 - 8 个碳原子的直链或支链烷基,Z 是由正羟基醇衍生的有机基,n 表示 1 - 4 的整数,通过酯交换反应,使用单烷基
锡化合物作为催化剂,可以高质量、高产率地生产
酯类化合物。
