摘要
试验采用盐析萃取工艺对焦化精苯废酸进行处理回收,结果表明,在一定的比例下可获得最佳萃取分离效果,酚相萃取液可进行二次利用,回收的净化酸可用于硫铵制备。
The salt-out extraction process is used to deal with the waste acid from benzol refining.Experimental results show that,optimal separation can be obtained under the condition of proper proportion;extractant and crude phynol can be recycled.The acid purified can be used in the production of ammonium sulfate.
