摘要：在无溶剂条件下,以无机盐CuSO4,Cu(NO3)2.3H2O,CuCl2.2H2O,FeCl3.6H2O为催化剂、以空气中的O2为氧化剂,通过苯甲醇氧化反应制备了苯甲酸。考察了无机盐种类、反应时间、催化剂用量与苯甲酸收率的关系,研究了催化剂的回收与循环使用情况,并对反应机理进行了推测。实验结果表明,Cu(Ⅱ)无机盐的催化活性高于Fe(Ⅲ)无机盐;Cu(Ⅱ)无机盐在无溶剂条件下可有效催化苯甲醇的氧化反应高收率制得苯甲酸。在苯甲醇用量为0.02mol、CuSO4与苯甲醇的摩尔比为0.082、NaOH用量0.0250mol、反应时间90min的条件下,苯甲酸收率最高,达到98.4%。该反应过程中无废弃物排放,属于环境友好的绿色化学反应。
Catalytic activity of inorganic salts CuSO4, CuCl2 · 2H2O, Cu（ NO3 ） · 3H2O and FeCl3 · 6H2O in oxidation of benzyl alcohol to benzoic acid with oxygen were studied with free-solvent. Effect of inorganic salt type, reaction time and catalyst dosage on yield of benzoic acid was investigated. Recycle of catalyst was observed and reaction mechanism was proposed. It is found that Cu （ Ⅱ ） salts are more active with high yield of benzoic acid than Fe （ Ⅲ ） salt. Under reaction conditions of benzyl alcohol 0.02 mol, mole ratio of CuSO4 to benzyl alcohol 0. 082, NaOH 0. 025 0 mol and reaction time 90 min, yield of benzoic acid can mount to 98.4%. The reaction was environment friendly and no waste was produced during the process.
