    摘要: Esters of monocarboxylic acids are transesterified with 1,2- and 1,3-polyols by reaction in the presence of a catalytically effective amount of a dialkyltin oxide blended with an excess of dialkyltin dichloride, so that a polyol ester of the monocarboxylic acid is formed. A transesterification reaction of alcohols and polyols with methyl or ethyl mono- or polycarboxylic acid esters utilizing a dimethyltin catalyst is also disclosed, in which the alcohol or polyol carboxylic acid ester formed is essentially free of the organotin catalyst. Carboxylic acid esters produced by the described methods, as well as carboxylic acid esters that are free of organotin catalysts are also disclosed.
