A PROCESS FOR THE MONOACYLATION OF POLYOLS WITH ALKYL AND ARYL BETA-KETOESTERS

Abstract A process for the monoacylation of polyols with alkyl and aryl Beta-Ketoesters. A process for the monoacylation of polyols with alkyl and aryl Beta-ketoesters comprising the steps of preparing a mixture of polyol and beta-ketoesters in the proportion range (molar ratio) of 4 to 8 of polyol and 1 of beta-ketoesters, exposing the said mixture to microwave irradiation of 2450 MHz frequency for a period of 1 -15 minutes in the presence of a thermally stabilising agent, to yield monoacyl polyol.
Full Text







The solution (reaction mixture with ethyl acetate) is concentrated and the product purified by column chrmatography to give a yield of 63-92% of monoacyl polyol.






We Claim;
1. A process for monoacylatiojn of polyols with alkyl and aryl β--
ketoestors comprising the steps of prepsring a mixture of polyol and
with in the proportion range (molar ratio) of 4 to 8 of
polyol and 1 of betarketoesters; exposing the said mixture to


7. Monoacyl polyols of alkyl and aryl β-ketoesters whenever prepared by a process as claimed in any one of the preceding Claims.
