Abstract: Microwave irradiation method appears to be a practical and valuable clean production technique for anthraquinone synthesis in dry media,with rapid reaction rate,higher productivity and less pollution than the traditional technique.The best reaction conditions of anthraquinone synthesis are observed and got through orthogonal test.This paper emphasizes on the relationship between productivity of anthraquinone and four factors:microwave power,microwave irradiation time,the proportion between orthobenzoyl benzoic acid (OBBacid) and catalyst,and the proportion between heating bath substances
