Sulfonated charcoal as a mild and efficient catalyst for esterification and trans-esterification reactions

摘要

Sulfonated charcoal was found to be an efficient heterogeneous catalyst for the acetylation of alcohols in acetic acid.Esterification of different carboxylic acids with different alcohols was also achieved with this catalyst.Acetylation and formylation of alcohols can also be catalysed efficiently in ethyl acetate and ethyl formate in high yields.
