发明名称 Process for the preparation of substituted hydroxyhydrocinnamate esters
摘要 The transesterification of substituted lower alkyl hydroxyhydrocinnamates with a higher alcohol or a polyol is greatly facilitated by the use of a trace amount of a tin catalyst. In many cases, the amount of the catalyst is so small that it is unnecessary to remove it from the final product by distillation of said product.
