探索了以5-羟甲基糠醛为原料,用高锰酸钾法氧化制备标题化合物。以126 mg(1 mmol)5-羟甲基糠醛为定量,考察了高锰酸钾用量、碱溶液的浓度和反应时间对反应的影响。当高锰酸钾用量为379.2 mg(2.4 mmol),碱溶液的浓度为2.2 mol/L,反应时间为10 min时,得到标题化合物收率为76.3%。研究结果表明,高锰酸钾法制备标题化合物,是一种不用贵金属催化剂,在室温下就可反应的简便方法。
The title compound was prepared by oxidation of 5-hydroxymethylfurfural with potassium permanganate. The effects of potassium permanganate concentration, concentration of alkali solution and reaction time on the reaction were investigated quantitatively with 126 mg (1 mmol) 5-hydroxymethylfurfural. When the amount of potassium permanganate was 379.2 mg (2.4 mmol), the concentration of alkali solution was 2.2 mol / L and the reaction time was 10 min, the yield of the title compound was 76.3%. The results show that the potassium permanganate method for the preparation of the title compound is a simple catalyst that can be reacted at room temperature without the use of noble metal catalysts.
