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.
