乙二醇催化氨化合成乙二胺
Synthesis of Ethylenediamine by Catalytic Ammoniation of Ethylene Glycol
摘要
Abstract
To explore a new green process for synthesis of ethylenediamine, ethylenediamine was prepared by catalytic amination of ethylene glycol in the presence of supported two-component composite metal oxides NiO/CuO/Al2O3 catalyst.The structure of the catalyst was characterized by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS) methods.The reaction mixture was analyzed by gas chromatography(GC).The effects of catalyst composition, material ratio, temperature and reaction time on the reaction were investigated.The selectivity of ethylene diamine could reach 56.7% under the condition that n(Ni)∶n(Cu) ratio was 3∶1, catalyst loading was 3%, NH3/HOCH2CH2OH mass ratio was 4∶1, and the reation was performed at 180 ℃, 0.6 MPa and for 4 h.Compared with traditional dichloroethane method, this process is more clean and friendly.关键词
