Abstract
A study has been made of the influence of the nature of the cobalt cat alyst, the solvent and the concentrations of the reagents on the hydro carbomethoxylation of methyl ester of undecylenic acid. With catalysis by cobalt carbonyl or acetate promoted by a pyridine addition, in met hanol (120 degrees C, p(CO) = 4.5 MPa) the reaction leads to dimethyl ester of 1,10-decanedicarboxylic acid in a 70-75% yield, with a low co ntent of the second regioisomer.
