为克服常规制备聚醚胺需要高温、高压等苛刻反应条件的不足，制备了一种Pd-Mg-Ba/r-Al₂O₃型催化剂，探索了聚醚在常压下催化胺化的可行性。主要考察了催化剂活性组分质量分数、反应温度、氢气用量、氨气用量、进料速率对胺化反应的影响。确立了反应合适条件为：催化剂组成Pd （0.5%）-Mg （2%）-Ba （2%）/r-Al₂O₃，反应温度为200℃，氨气、氢气用量为n（聚醚）：n（NH₃）：n（H₂）=1：8：8，反应空速为0.3 h^-1。同时，利用核磁共振波谱及化学分析对产品结构及性质进行了分析。结果表明，该常压工艺为后续工业常压生产提供重要依据。

In order to avoid the rigorous reaction conditions in the synthesis of polyether amine such as high temperature and high pressure,a kind of Pd-Mg-Ba/r-Al₂O₃ catalyst is prepared and then used to seek for the feasibility of conducting the reaction under atmospheric pressure.The influences of the mass concentration of catalyst active components,reaction temperature,H₂ dosage,NH₃ dosage and feed rate on the amination reaction are studied.The suitable reaction conditions are determined as follows:the composition of catalyst is Pd(0.5%)-Mg(2%)-Ba(2%)/r-Al₂O₃,reaction temperature is at 200℃,n(polyether):n(NH₃):n(H₂)=1:8:8,and WHSV is 0.3 h^-1.The gained products are characterized by NMR and chemical analysis.This research can provide helpful support for the application of atmospheric pressure process in industrial production.
