ABSTRACT:
A process for the preparation of a cyclic alkylene carbonate ester which comprises reacting in a liquid phase a cyclic or linear olefin having from 2 to 15 carbon atoms with carbon dioxide at a temperature of from 30.degree. to 160.degree. C., at a total pressure of from 100 to about 2,000 psig and a pH value of between about 4 and 8, in the presence of oxygen or an oxygen-containing gas and a catalytic amount of a mixture of (a) iodine or an iodide of a metal selected from Groups IA, IB, IIA, IIB, VB, VIIB and VIII of the Periodic Table of Elements, (b) a carbonate of a metal selected from Groups IB, IIA, IIB and VIII of the Periodic Table of Elements, (c) a catalytic iron compound and (d) a catalytic soluble cupric salt, and recovering resulting cyclic alkylene carbonate ester.
