研究了活性炭负载磷钨酸催化剂在微波辐射下合成尼泊金丁酯,考察了不同催化剂、不同加热方式、微波辐射功率、微波辐射时间等因素对产物收率的影响。结果表明,活性炭负载磷钨酸是合成尼泊金丁酯的良好催化剂,不仅无毒、无腐蚀、环竟污染小,且易于分离,可循环使用,尤其在微波辐射下反应,使反应速率和收率大大提高。在优化条件下酯收率达93.3%。 The effects of different catalysts, different heating methods, microwave radiation power, microwave irradiation time and other factors on the yield of the product were investigated. The results show that activated carbon supported phosphotungstic acid is a good catalyst for the synthesis of butylparaben, not only non-toxic, non-corrosive, the ring actually small pollution, and easy to separate, can be recycled, especially under microwave irradiation, the reaction rate and The yield is greatly increased. Under optimized conditions, the yield of ester reached 93.3%.
