Abstract

In situ diffuse reflectance Fourier-transform infrared spectroscopy was used to perform mechanistic investigation on the synthesis of N-alkylmorpholines from diethylene glycol (DEG), alcohol and ammonia. The results showed that the synthesis of N-alkylmorpholines on a heterogeneous catalyst proceeded along the reaction path between DEG and alkylamine when choosing CuO–NiO/γ-Al2O3 as a suitable catalyst. In addition, the yield of methylmorpholine and ethylmorpholine was 86.4 and 76.6 %, respectively.
