專利摘要(中)
本發明提供一種複合式固體鹼觸媒的製備方法，其包含進行一溶液準備步驟、進行一滴定步驟、進行一熟化步驟以及進行一鍛燒步驟。溶液準備步驟用以得到前驅物溶液，其中前驅物溶液含有鎂離子以及鋁離子。滴定步驟係將前驅物溶液以逆向滴定的方式滴入氨水溶液中，並均勻攪拌形成觸媒母液。熟化步驟係將觸媒母液進行熟化以形成觸媒前驅物。鍛燒步驟係將觸媒前驅物於流動空氣下鍛燒，以得到複合式固體鹼觸媒。藉此，本發明可調控鎂鋁莫耳比以及鍛燒溫度以優化觸媒，可有效地應用於催化甲醇與環氧丙烷，合成出丙二醇甲醚。

專利摘要(英)
The present disclosure provides a method for fabricating a composite solid base catalyst. The method includes a solution preparation step, a titration step, an aging step, and a calcining step. The solution preparation step is provided for obtaining a precursor solution, and the precursor solution contains a magnesium ion and an aluminum ion. The titration step is provided for dropping the precursor solution into the ammonia solution by back titration, and stirring uniformly to form the catalyst mother liquor. The aging step is provided for aging the catalyst mother liquor to form a catalyst precursor. The calcining step is provided for calcining the catalyst precursor under flowing air to obtain the composite solid base catalyst. Accordingly, the present disclosure can control the molar ratio of magnesium to aluminum and the calcination temperature to optimize the catalyst. The catalyst can be used to catalyze methanol and propylene oxide to synthesize propylene glycol methyl ether.
