Application of triethylamine and imidazole to The transesterificaiton reaction

摘要

Transesterification of methanol with ehtyl acetate and ethyl benzoicate was studied using treigthylamine (TEA) and imidazole (IMZ) as the catalysts. The experimental results demonstrated that both triethylamine and imidazole have lower transesterification catalytic activities in the absence of propylene oxide (PO) promoter, whereas they have higher trans- esterification catalytic activities in the presence of PO promoter.
