| Abstract: | 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. |
