Direct hydroxylation of p-xylene to 2,5-xylenol with hydroxylamine was carried out in an ionic liquids/molybdenum catalytic system. High 2,5-xylenol selectivity (80-98 %) can be achieved with good p-xylene conversion (5.9-9.9 %) in this catalytic system. The recycling experiments suggested the ionic liquids/molybdenum catalytic system was stable enough to be recycled for the hydroxylation reaction.
在离子液体/钼催化系统中,使用氢氧胺直接对对二甲苯进行氢氧化反应生成2,5-二甲醇。该催化系统中可以实现高达80-98%的2,5-二甲醇选择性,以及良好的对二甲苯转化率(5.9-9.9%)。回收实验表明,离子液体/钼催化系统具有足够的稳定性,可以重复用于氢氧化反应。
