摘要
采用电石渣作皂化剂的氯醇法生产环氧丙烷(PO),其碱度会对下游产品产生影响,而目前PO碱度检测无国家标准可参考。为了有效检测PO中的碱度,本文研究建立了一种自动电位滴定仪测定方法。实验结果表明,该方法的精密度和准确度符合要求,且操作简单。
At present, the normal ehlorohydrination of carbide slag as saponification agent to produce the propylene oxide （denoted as PO） has a negative effect for the down-stream product, and the alkalinity of PO has not been exactly detected so far. Herein, we develop an efficient automatic potentiometric tritration method to detect the alkalinity of PO sample. In conclusion, a facile method can be employed to mensurate the alkalinity of PO, and the results are much more accurate than normal measurement method.
