摘要(Abstract):
以Cu Cl2-Fe Cl3混合金属盐水溶液为催化剂,以正己醇为溶剂进行2,3,6-三甲基苯酚(TMP)多相氧化反应。通过副产物2,2',3,3',5,5'-六甲基-4,4'-联苯二酚(IP)和中间产物4-氯-2,3,6-三甲基苯酚(Cl TMP)生成情况推测Cu Cl2和Fe Cl3催化反应网络。研究结果表明副产物IP主要在反应初始阶段生成,Cl?通过促进中间产物Cl TMP生成进而抑制副反应。反应温度为358.15 K,Cu Cl2使用量7.57%(mol),Fe Cl3使用量3.78%(mol),反应进行8 h,目的产物即2,3,5-三甲基-1,4-对苯醌(TMQ)收率为80.66%。
