| Abstract: | A new synthetic route is to start directly from benzene and formaldahyde to form ether and alcohol by shape-selective catalyst w ith zeolites.When shape-selective catalyst 2% PZSM-5 was used at 200～210 ℃ under normal pressure,mole ratio of benzene to formaldehyde being 1.0∶2.6,the conversion of benzene reached 51.98% and the selectivity for benzyl alcohol re ached 53.10%. |
