Gas phase imidazole methylation on zeolites and HPA/SiO2: Study of acid site requirements and catalyst deactivation
(Elsevier Inc, 2013-07)
The gas-phase alkylation of imidazole with methanol was studied at 523 K on solid acids such as HPA/SiO2 and zeolites HMCM22, HBEA, NaY, ZnY and HY. The nature, density and strength of acid sites were determined by temperature ...
