阐述了1.4-丁二醇在生产过程中,用浓硫酸处理乙炔气时所形成黑色粘稠、具有刺鼻恶臭味的黑色粘稠液体,通过大量的实验研究,研究出一种特殊回收废硫酸工艺进行处理,为其找到了具有循环利用的价值。
In the process of production of 1.4-butanediol, the black viscous, pungent and stinky black viscous liquid formed by the treatment of acetylene gas with concentrated sulfuric acid is described. Through a large amount of experimental research, a kind of special recovery waste Sulfuric acid process for processing, found for its recycling value.
