Process for the preparation of substituted hydroxy-hydrocinnamate esters |
摘要 |
<p>The transesterification of substituted methyl or ethyl 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.</p> |
