权利人:EASTMAN KODAK CO
摘要:A PROCESS FOR THE SYNTHESIS OF PHENYL ESTERS DIRECTLY FROM THE CORRESPONDING PHENOLS AND CARBOXYLIC ACIDS WHICH COMPRISES CONTACTING A PHENOLIC COMPOUND HAVING AT LEAST ONE HYDROGEN ATOM ADJACENT THE ACTIVE HYDROXYL GROUP WITH A CARBOXYLIC ACID COMPOUND CONTAINING AT LEAST ONE ACTIVE CARBOXYLIC GROUP IN THE PRESENCE OF A CATALYTIC AMOUNT OF A BORATE-SULFURIC ACID CATALYST COMPLEX. THE PROCESS IS CARRIED OUT IN A SINGLE STAGE REACTOR WHICH MAY BE OPERATED AT FROM 75*C. TO 285*C. UNDER ATMOSPHERIC, SUBATMOSPHERIC OR SUPERATMOSPHERIC PRESSURE. IF DESIRABLE, A SOLVENT CAN BE EMPLOYED.
