ABSTRACT:
4-Alkyl-2-morpholinones are prepared by bringing an N-alkyldiethanolamine into contact with a zinc oxide promoted copper catalyst in the presence of hydrogen under reaction conditions including a temperature within the range of about 240.degree. to about 400.degree. C. and a pressure within the range of about 0 to about 300 psig and by recovering the 4-alkyl-2-morpholinone that is formed by the reaction.
