| Abstract: | A method was developed for determination of pure magnesium in grignard reagent chlorovinyl magnesium.The left pure magnesium in grignard reagent chlorovinyl magnesium reacted with dibromethane completely at low temperature.The consumption of dibromethane was determined by gag chromatography with diphenyl as internal standard and the content of pure magnesium in grignard reagent chlorovinyl magnesium was calculated according the consumption of dibromethane.This method was accurate,stable and with good reproducibility and RSD less than 1.5%.It can be used as the quality control standard for chlorovinyl magnesium |
