PROCESS FOR THE CARBONYLATION OF ETHYLENICALLY UNSATURATED COMPOUNDS

摘要

A PROCESS FOR THE CARBONYLATION OF ETHYLENICALLY UNSATURATED COMPOUNDS IS DESCRIBED. THE PROCESS COMPRISES REACTING AN ETHYLENICALLY UNSATURATED COMPOUND WITH CARBON MONOXIDE IN THE PRESENCE OF A SOURCE OF HYDROXYL GROUPS AND A CATALYST SYSTEM. THE CATALYST SYSTEM IS OBTAINED BY COMBINING :(a)METAL OF GROUP VIII OR A COMPOUND THEREOF : AND @(b)A BIDENTATE PHOSPHINE OF GENERAL FORMULA (I)(FORMULA I)THE CARBONYLATION REACTION IS CARRIES OUT AT A TEMPERATURE OF BETWEEN -30°C TO 49°C AND UNDER A CO PARTIAL PRESSURE OF LESS THAN 30 X 105 N.m-2.
