Abstract
This paper studies the synthesis process of p nitrophenetol by phase transfer catalyist.The Effect factors on the quality and the yield of the product are discussed by a series of experiment which include selecting of the catalyst and optimizing of reaction and recycling of liquid and catalyst.The best technological conditions are determined. The content of the p nitrophenetol is over 99.5%.The mp of the product is over 57?℃ and the yield reaches to 95%.This process has the adventage of gentle reaction and short period and avoiding reuse of ethylalcohol and higher yield and less pollution.
