Reaction Conditions

Reaction Steps

5 g (0.05 mol) of MAA, 100 g of tetrahydrofuran, 9 g (0.06 mol) of dicyclohexylamine, 4 g of ammonia and 10 g of catalyst B were introduced into an autoclave fitted with a gas-distribution stirrer. The autoclave was subsequently heated to 225° C., and hydrogen was injected into the autoclave at a pressure of 200 bar. When take-up of hydrogen was no longer observed, the reaction was terminated. Analysis of the reaction mixture by gas chromatography gave a yield of 8.8% of N-cyclohexylpyrrolidone.
