Abstract
1335870 Carboxylic acids SNAM PROGETTI SpA 1 July 1971 [2 July 1970] 30975/71 Heading C2C Carboxylic acids are prepared by subjecting a mono-metallic salt of a carboxy sulphonic acid to pyrolysis. The carboxysulphonic acid preferably has the general formula wherein R and R<SP>1</SP>, which may be the same or different, are each a hydrogen atom, a saturated or unsaturated, cyclic or acyclic aliphatic hydrocarbon radical having up to 12 carbon atoms and which is optionally substituted by at least one group selected from -COOH and -CN; or aromatic hydrocarbon radical which optionally contains an alkyl substituent having up to 12 carbon atoms; or R and R<SP>1</SP> together form a saturated or unsaturated ring optionally substituted by at least one alkyl, anhydride or lactam group.
