Title: Alkylation of phenol with isopropanol over tungstosilicic acid modified zeolite ZSM-22
Abstract: Employing XRD and BET showed ZSM-22 structure with highly ordered crystalline structure;NH3-TPD was used as ZSM-22 surface acidity of test;Alkylation of phenol with isopropanol over zeolite ZSM-22 occurred.The result showed that under optimal reaction conditions of temperature of 260℃,WHSV of 1.8h-1,Catalyst Loading of 0.3g,nIPA/nPhenol of molar ratio of 0.8,phenol conversion rate can be achieved 70%,the total of selectivity o-isopropyl phenol and isopropyl phenol was 86.14%.After impregnation of tungstosilicic acid in zeolite ZSM-22,phenol conversion rate can reach to 68.29% under tungstosilicic acid content of 10%.
