  • Manufacture of butenediol diesters
    Patent number: 4239910
    Abstract: In a process for the manufacture of butenediol-dicarboxylic acid esters by reacting butadiene with oxygen and a carboxylic acid in the presence of a noble metal catalyst containing platinum or palladium, the carboxylic acid is added to the reaction mixture in the form of the ester of the acid with a low molecular weight aliphatic alcohol such as methanol and the reaction is carried out under conditions under which the ester undergoes hydrolysis, or the hydrolysis is carried out before the main reaction. This enables the carboxylic acid obtained on further processing of the butenediol esters to be recycled.
