摘要
研究了回收苯乙酸的新方法,将含有苯乙酸的废水经过固体化,溶解于甲苯中,然后利用浓硫酸强氧化性除去杂质,氢氧化钠碱化、分离、脱色,再酸化得到纯净苯乙酸。
This article studied the new method of benzeneacetic acid recovery,the wastewater was contained solid acid,and dissolved in toluene and then concentrated sulfuric acid to remove impurities strong oxidizing sodium hydroxide alkalization,separation,decolorization,and then acidified to be pure phenylacetic acid.
