TL;DR: In this paper, a method for synthesizing 2,6-xylene and o-cresol by means of co-production is presented, which includes steps loading iron composite oxide catalysts into a fixed-bed reactor; preparing the o cresol and the 2, 6-xylenol by reaction under certain conditions, such as that dimethyl ether with the flow rate of 5-50mL/min is used as carrier gas, a molar ratio of phenol to methanol is 1:1-20, the phenol and methan
Abstract: The invention discloses a method for synthesizing 2,6-xylene and o-cresol by means of co-production The method includes steps loading iron composite oxide catalysts into a fixed-bed reactor; preparing the o-cresol and the 2,6-xylenol by means of reaction under certain conditions The certain conditions includes that dimethyl ether with the flow rate of 5-50mL/min is used as carrier gas, a molar ratio of phenol to methanol is 1:1-20, the phenol and the methanol are used as raw materials, the temperatures are 300-400 DEG C, and the weight space velocity of the phenol is 01-1h A molar composition ratio Fe:Zr:Ti:Si:Cs of the iron composite oxide catalysts is 1:(005-10):(001-01):(001-01):(0001-001) The method has the advantages that the dimethyl ether is used as the carrier gas, so that decomposition of the methanol can be prohibited in reaction procedures, the methanol utilization rate can be obviously increased, and the service lives of the catalysts can be prolonged
