Abstract
The addition of glyoxylic acid ethyl ester to unsaturated fatty acid derivatives occurs with a maximum yield of 89%. The products are the corresponding 1:1-adducts. Temperature, reaction time, stoichiometry, and the concentration of the fatty acid derivative were investigated and optimized. A maximum yield was obtained with a fourfold excess of oleic acid ethyl ester, a reaction temperature of 200°C, a reaction time of 24 h, and an oleic acid ethyl ester concentration of 1.3 mol/l.
