Abstract

1,189,400. Unsaturated aliphatic carboxylic acids and lactones. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 30 Aug., 1968, No. 41520/68. Heading C2C. One or more unsaturated aliphatic carboxylic acids and/or one or more lactones of aliphatic hydroxy carboxylic acids are prepared by contacting one or more non-alpha hydroxy- or chloro-substituted aliphatic carboxylic acids having at least three carbon atoms in their molecules with one or more non-basic metal salts derived from one or more inorganic acids at an elevated temperature.
