Abstract
The carbonylations of diethylamine and triethylamine were conducted in a pressure reactor using K[Ru”‘(EDTA-H)Cl] l2H z0 as catalyst at a CO pressure of 5 - 26 atm and temperature in the range 80 - 100 “c in aqueous medium. The products of carbonylation of diethylamine were NJVdiethylformamide (80%) and N,N-tetraethylurea (20%), whereas triethylamine gave 100% NJVdiethylpropionamide. The observed rates for the carbonylation of diethylamine and triethylamine show first order dependence with respect to catalyst, substrates and dissolved CO concentrations. The effect of temperature was also studied on the rate of carbonylation, and from the graph of -ln rate us. l/T, the activation energies were evaluated. Mechanisms are proposed for K[ Ru”‘( EDTA-H)Cl] - 2H,O-catalyzed carbonylation of diethylamine and triethylamine.
