MNT废酸用甲苯萃取工艺的探讨

A Study on the Extraction from the Waste Acid of Mono - nitrotoluene by Toluene

介绍硝基甲苯废酸用甲苯萃取的工艺选择,经萃取可回收废酸中的硝酸和硝基化合物,并不需脱硝,直接进行浓缩。

This paper reports a process technology to extract the organic compounds from the waste acid of mono -nitr otoluene (MNT) by toluene to recover nitric acid and nitro- compounds. Then, the waste acid may be concentrated directly without a prior de- nitration.
