Methods for esterification in the presence of a sulfonated, halogenated and base treated styrene DVB copolymer catalyst.

摘要

The present invention provides a system, method and catalyst for esterification. The method of esterification includes adding to reactants of a reaction a base treated, sulfonated, halogenated thermally stable catalyst. The catalyst provides high selectivity and does not readily degrade at high temperatures. The esterification reaction are used to prepare an acetate ester, an acrylic ester, a natural fatty acid ester, a sorbitol derived ester, a phthalate, and/or a benzoate and ester derived from maleic anhydride. A system for esterification, and ester utilizing the method are also provided. Various downstream products are made from the esters created using the method described herein are made including a solvent for a surface coating, an ink, a textile, an adhesive, a plastic, a cosmetic, a surfactant, a detergent alcohol, a lubricant, a plasticizer, a flavor, and a fragrance.
