MeAPO-36 containing various types and concentrations of metals (Mn, Co, Mg and Zn) in the reaction mixture were synthesized. Various levels of crystallinity were observed depending on the type and concentration of these metals and crystallization parameter. Calcination of the samples at 550 C resulted in varying levels of reduction in crystallinity depending on the type of divalent metal incorporated. MeAPO-36 had the highest thermal stability. Ammonia TPD and IR spectrum of pyridine absorption show that MeAPO-36 have concentrations of both Bronsted and Lewis acid sites. Preliminary catalytic evaluation on a wide range of MeAPOs (metal-containing aluminophosphates) show that they were active for the hydroxylation of phenol. Results are presented
