Abstract
A supported heteropoly
acid catalyst has been prepared and was investigated for the esterification of n butanol with
citric acid in the liquidsolid system.The effects of reaction conditions were investigated.The
most suitable conditions for the reaction are as follows:acid alcohol ratio 16.5(mol),mass ratio
of catalyst to acid 1.0%,reaction time 3h,reaction temperature 145.The experimental results
showed that the supported heteropoly acid catalyst had high catalytic activity and stability.
