6-叔丁基-3-甲基苯酚脱叔丁基制间甲酚
Dealkylation of 6-tert-Butyl-3-Methyl-Phenol to m-Cresol
摘要
Abstract
Dealkylation of 6-tert-butyl-3-methy-phenol(6B3MP) to m-cresol(MC) was studied in a fixed bed reactor under atmospheric pressure The effects of catalysts, namely zeolite ZSM-S, γ -Al2O) and concentrated sulfuric acid modified γ-Al3O,, solvents, namely ethanol, cyclohexane and benzene, and reaction temperature on the dealkylalion were investigated. The results showed thai under the conditions of γ -A12O3 as the catalyst. cyclohexane as the solvent, mole ratio of cyclohexane to 6B3MP 4.7 - 5.0. reaction temperature 250 - 270 ℃. and LHSV 2.4 - 6.0 h-1, the conversion of 6B3MP and the selectivity to MC reached 99.79% and 100.00%. respectively.关键词
