作者合成了一种十聚钨酸十六烷基吡啶催化剂,通过红外光谱方法对其结构进行表征,以质量分数为30%的H2O2为氧化剂,在回流温度下,十聚钨酸盐催化氧化苯甲醇可得到产率(基于苯甲醇)为90%—93%的苯甲酸。这是一条苯甲酸绿色合成的新途径,克服了目前有机化学实验教材中采用的浓HNO3或KMnO4氧化法存在的污染大、反应时间长等缺点。 The authors synthesized a cetylpentadienoic acid cetylpyridine catalyst, its structure was characterized by infrared spectroscopy, the mass fraction of 30% H2O2 as oxidant, at reflux temperature, decatungstate catalyzed oxidation of benzene Methanol provides 90% -93% yield of benzoic acid (based on benzyl alcohol). This is a new way for the green synthesis of benzoic acid, which overcomes the shortcomings of the existing HNO3 or KMnO4 oxidation methods used in organic chemistry experiment materials such as large pollution and long reaction time.
