Abstract
The carbonylations of diethylamine and triethylamine were conducted in a pressure reactor using K[RuIII(EDTA-H)Cl]·2H2O as catalyst at a CO pressure of 5-26 atm and temperature m the range 80-100°C in aqueous medium. The products of carbonylation of diethylamine were N,N-diethyl-formamide (80%) and N,N-tetraethylurea (20%), whereas triethylamine gave 100% N,N-diethylpropionamide. 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 -In rate vs. 1/T, the activation energies were evaluated. Mechanisms are proposed for K[RuIII(EDTA-H)Cl]·2H2O-catalyzed carbonylation of diethylamine and triethylamine.
