Abstract:Gas-phase alkylation of 3,5-xylenol by methanol over a catalyst containing iron oxide as the main component in a fixed-bed continuous process was studied.The effects of the support grill temperature,Cr content,the calcination temperature and time of catalysts were investigated.By means of some experiments,it was found that the catalysts had good activity and selectivity in the reactivity.
Key words:3; 5-xylenol; 2; 5-trimethylphenol; methylation; iron catalyst
