Preparation of esters of unsaturated monocarboxylic acids
Abstract
Abstract A PROCESS IS DISCLOSED FOR PREPARING SIMPLE, POLYMERIZABLE ESTERS OF UNSATURATED MONOCARBOXYLIC ACIDS BY EFFECTING RELEASE OF THE DESIRED ESTER BY MEANS OF A VACUUM DISTILLATION-DISPROPORTIONALTION OF THE DESIRED ESTER FROM A COMPLEX SULFATE MIXTURE CONTAINING THE NOVEL MONOSULFATE AND DISULFATE ESTER-SALTS OF THE DESIRED ESTER. THE SULFATE MIXTURE IS PREPARED BY REACTION UNDER ESSENTIALLY ANHYDROUS CONDITIONS OF AN ALPHA-MONOOLEFIN CONTAINING UP TO FIVE CARBON ATOMS WITH AN UNSATURATED MONOCARBOXYLIC ACID CONTAINING UP TO FOUR CARBON ATOMS IN THE PRESENCE OF AN EXCESS OF ANHYDROUS SULFURIC ACID. ETHYL ACRYLATE MAY THUS BE PREPARED FROM ETHYLENE, GLACIAL ACRYLIC ACID AND CONCENTRATED SULFURIC ACID.
