| 摘 要： | 工业上以环己烷制取环己酮的工艺中产生大量酸性废料 (该废料简称EI) ,废料中含有大量羧酸 ,以前多作为废料弃置 ,产生了严重的环境污染。采用废料EI与乙醇合成羧酸酯 ,以合成的羧酸酯为起泡剂 ,制成复合型浮选药剂ME ,用在平顶山气煤浮选工艺中 ,可改善浮选效果 ,具有明显的选择性优势

| Abstract: | Cyclohexane gets cyclohexanone in industry,this craft gives rise of much acid waste(EI),there are carboxylic acid in waste,it is thrown aside betore,and waste leads to grave pollution of the environment.This paper introduces this reaction:RCOOH+CH 3CH 2OHSP回流 RCOOCH 2CH 3+H 2O,RCOOCH 2CH 3 is a foam.It can manufacture compound flotation agent ME,and improve flotation result in gas coal flotation craft in Pingdingshan coal mine.There are clear superiority. |
