Abstract

ABSTRACT The performance of the CuO-NiO/γ-Al 2 O 3 catalyst used in the synthesis of N- alkylmorpholines from diethylene glycol, alcohol, and ammonia was studied. The catalyst was prepared with Ni and Cu as the active components, and the optimum contents were 4.2– 4.4% and 16.8–18.9%, respectively. The catalytic activity decreased rapidly as the catalyst deactivated gradually under the high temperature and liquid hourly space velocity ...
