Methylmagnesium chloride is used as Grignard reagent and alkylating reagent in organic synthesis. The synthetic method is: Feed the small amounts of chlorine methane gas in the synthesis under normal pressure bottle that 2.4g magnesium and the pure methylal of 40g are housed, after exothermic heat of reaction caused, it was complete to reactive magnesium slowly to feed methyl chloride gas again, promptly gets Grignard reagent-methylmagnesium-chloride.
