摘要 用过量的氯乙酸或氯乙醇,反应的pH值控制为9~10,可将硝基苯氧乙酸的产率从50%~60%提高到85%~92%,1,4-二羟乙基苯二醚的产率可达80%。 An improved method is provided for the prepara-tion of nitrophenoxyacetic acid.The yield ofnitrophenoxyacetic acid can be increased from 50%~60% to 85%~92% with the use of excess chloroaceticacid.The yield of 1,4-dihydroxyethyl phenyl diethercan reach to 80% by using excess chloroethanol.ThepH of the solution in these reactions must be con-trolled in the range of 9~10.
