【摘要】 高铁酸盐是绿色、无污染、高选择性和高活性的强氧化剂,可以氧化醇类、含氮化合物、烃类等有机化合物,其氧化性能可以通过改变反应条件(时间、温度及pH值)进行调解。本文以苯甲醇为原料,系统研究了在水相中用高铁酸钾氧化合成苯甲醛反应条件。在最佳反应条件18℃,pH值为11.5的氢氧化钠水溶液作溶剂,氧化剂加入量为化学反应的理论用量,反应4 min时,苯甲醇氧化为苯甲醛的选择性为82.3%,转化率为62.0%。结果表明高铁酸盐在有机物的氧化合成方面的应用,具有很好的发展前景。更多还原

【Abstract】 Ferrate is green, non - toxic, high selectivity, powerful oxidizing agent. It could oxidize alcohol, nitrogen - containing organic, even hydrocarbon et cetera, Its oxidizing ability could be adjusted an dcontrolled by changing reaction conditions (reaction time, temperature and pH value). The reaction con ditions which potassium ferrate oxidize benzal alcohol to benzaldehyde in water are studied. The optimum reaction - conditions are temperature of 18℃, the NaOH aqueous solution ( pH=11.5) as solvent, theoretic reactant ratio amount of oxidant an reaction time of 4 minutes. At this condition the selectivity of the benzaldehyde is 82.3 % and the conversion of the benzal alcohol is 62.0% . Results in dicate that potassium ferrate have bright developing propect in organic synthesis.更多还原
