Progress in Synthesis of 1,4-Naphthquinone

1,4-naphthoquinone is an important organic product of tine chemical industry, and it is mainly used to synthesize the organic compounds of medicine, pesticide and dyestuff. The primarily synthesis methods are liquid-phase oxidalion and gaseous-phase oxidation. In this paper, the progresses in study on these two methods are introduced. Up to flOW, the liquid-phase electro-oxidation is widely used, and there is a longer time in the industrial production. The gaseous-phase catalytic oxidation is a novel method, and there are more advantages than the liquid-phase oxidation. In the future, the study on choosing a suitable catalyst will become the key point. Other two methods are also introduced, which are microwave radia- tion and ultrasonic radiation, the effect factors on the yield of 1,4-naphthnquinone are detailed.
