Abstract

1289243 Production of lactones LEUNAWERKE "WALTER ULBRICHT" VEB 25 March 1971 7796/71 Heading C2C Lactones are obtained by reacting cyclic ketones with an adduct of urea and hydrogen peroxide in the presence of formic acid at a temperature of 0-100‹ C. The urea-hydrogen peroxide adduct is preferably used in a molar excess relative to the cyclic ketone, e.g. in a molar ratio between 1À1 and 2À5 : 1, and the reaction may be conducted in an organic solvent. Specified cyclic ketone starting materials are cyclopentanone, cyclohexanone, and 2 - methyl-, 3 - methyl-, 4 - methyl-, 4 - tertbutyl-, and 2-cyclohexyl-cyclohexanone.
