摘　　要：微波辐射化学是研究在化学中应用微波的一门新兴的前沿交叉学科,具有显著的节能、提高反应速率、缩短反应时间、减少污染,且能实现一些常规方法难以实现的反应等优点.2-叔丁基对苯二酚是一种新型的食品抗氧剂,具有高效、低毒、热稳定性好的优点.报道了微波技术制备2-叔丁基对苯二酚(TBHQ)的方法,考察了微波功率、微波辐射时间、催化剂、溶剂等对反应的影响,确定了最佳反应条件:在微波辐射功率400 W,反应时间30 min的条件下,产物收率达52.3%.The 2-tert-butylhydroquinone （TBHQ） is an excellent antioxidant for edible oils and fats. The synthesis of TBHQ with the help of microwave irradiation was studied. The effect of the irradiation power, reaction time, solvent and catalyst has been investigated. With an irradiation power of 400 W the synthesis yield reached 52.3 % in 30 minutes. Compared with traditional methods, the proposed method has advantages of less reagent consumption, high yield and short reaction time.
