ABSTRACT: Based on starch and series of alkyl benzene sulfonic acid as the materials, a novel carbon-based
solid acid catalyst is synthesized using hydrothermal method. This catalyst exhibits much higher
catalytic activity in the reaction of esterification of Mono-fatty alcohol polyoxyethylene maleate
esters with 1,4-butanediol. The structure of carbon-based solid acid catalyst was charactered by
IR and XRD, characterizations showed that this catalyst exhibited high –SO3H loading. Reusability
of the carbon-based solid acid catalyst for esterification showed that after recycling five times the
activity remained unchanged.
