摘要:探讨了用电位滴定法分别测定二丁基镁产物中格氏试剂含量和总氯含量.格氏试剂C4H9MgCl在酸性水溶液中水解,采用电位滴定法进行含量测定;总氯测定是将有机氯在NaOH和C2H5OH的混合溶液作用下水解为Cl-,然后进行测定.测定结果的相对标准偏差为0~2.2%,用标准加入法做回收率实验,结果在95.2%~108.4%之间.

This paper studied the content determination of Grignard reagent and total chlorine by potentiometric titration in dibutylmagnesium. The concentration of Grignard reagent C4H9MgCl was determined by potentiometric titration after it was hydrolyzed in acidic aqueous solution. The sample was added into the mixture solution of NaOHC2H5OH,after chlorine changed into Cl-,then the total chlorine determination was carried out. The relative standard deviation of determination results was 0—2.2%,and the recovery range was 95.2%—108.4% through the method of standard addition.
