Abstract

Process for preparing unsaturated carboxylic acids having the general formula: ** (See formula) ** wherein each of the R, R ', R "and R"' 'individually represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and/or salts or esters of these acids, which The process comprises reacting a compound of the general formula: ** (See formula) ** where R, R ', R "and R" "have the above meanings, with activated oxygen, giving an epidioxide having the general formula: ** (See formula) ** where R, R ', R "and R' '' have the above meanings, and redistribute this epidioxide in the presence of alkali, to obtain the unsaturated carboxylic acid and/or a salt thereof, and, optionally, esterify or form a salt of acid.
