Abstract
1354466 Carboxylic acids and derivatives IMPERIAL CHEMICAL INDUSTRIES Ltd 28 Oct 1971 [9 Nov 1970] 53119/70 Heading C2C Carboxylic acids and derivatives thereof (e.g. lactones) are prepared by contacting (e.g. at up to 200‹ C.) an acyclic olefinic, an aromatic or a heterocyclic compound containing at least one H atom linked to a C atom attached to a double bond with a carboxylic acid or acarboxylic acid derivative containing a H atom linked to a C atom α to the carboxyl group in the presence of pentavalent vanadium ions and under anhydrous conditions or in the presence of up to 10% by volume water, the vanadium which is reduced in the reaction being reoxidized directly by contact with O 2 or a gas containing the same. A carboxylic acid anhydride, a nitrile and/or carboxylate ions may be present in the reaction solution, the latter preferably containing 0À001- 5% by weight of V. The examples refer to the preparation of γ- butyrolactone from ethylene and acetic acid.
