Cu/FSM-16催化苯酚与过氧化氢反应合成苯二酚
Hydroxylation of Phenol With Hydrogen Peroxide to Dihydroxybenzene Over Cu/FSM-16
【摘要】 以Cu/FSM-16为催化剂,以水为溶剂,催化氧化苯酚与过氧化氢羟基化反应合成对苯二酚和邻苯二酚,考察了Cu/FSM-16中Cu的负载量、Cu/FSM-16催化剂用量、反应时间和温度等影响因素。结果表明,在优化反应条件下,苯酚转化率可达到22.7%,苯二酚的选择性为87.4%,并且该催化剂可以重复使用。
【Abstract】 With Cu/FSM-16 as catalyst and water as solution,catechol and hydroquinone were synthesized from phenol reacting with hydrogen peroxide.The effects of Cu loadings in Cu/FSM-16,the dosage of Cu/FSM-16 catalyst,reaction time and reaction temperature on the hydroxylation of phenol were investigated.The results showed that under the optimal reaction conditions the conversion of phenol and selectivity of dihydroxybenzene reached 22.7% and 87.4%,respectively,and the Cu/FSM-16 catalyst could be reused.
