研究了1,4-丁二醇在Cu-ZnO-Al_2O_3;催化剂上液相脱氢环化制γ-丁内酯反应过程,并探讨反应机理.对实验数据进行拟合,得到该反应速率方程. The reaction process of 1,4-butanediol on γ-butyrolactone was investigated by liquid phase dehydrogenation of 1,4-butanediol on Cu-ZnO-Al_2O_3 catalyst and the reaction mechanism was discussed. The experimental data were fitted to obtain the reaction rate equation .
