Abstract
1,153,115. Hydrodimerization of acrylic acid derivatives. UCB (UNION CHIMIQUECHEMISCHE BEDRIJVEN) S.A. 5 Feb., 1968 [8 Feb., 1967], No. 5659/68. Heading C2C. A process for the hydrodimerization of acrylic acid derivatives selected from acrylonitrile, C 1 to C 4 alkyl acrylonitriles and C 1 to C 4 alkyl esters and amides of acrylic acid by reaction with an alkali metal amalgam, which comprises carrying out the reaction in a non-polar, at least partly water-miscible solvent medium containing a free quaternary ammonium base preferably of the formula in which R 1 , R 2 , R 3 and R 4 , which may be the same or different, are alkyl, cycloalkyl, aryl or aralkyl radicals; and water, the process being performed, without pH control at the degree of alkalinity generated by the reaction, preferably at a temperature between -10 and +30 C. Suitable solvents mentioned are ethers, e.g. tetrahydrofuran, dioxan, dimethoxyethane and diglyme (diethyleneglycol dimethyl ether).
