Abstract
This invention relates to an improved liquid phase chlorination process for the chlorination of methyl chloride to preferentially produce methylene chloride. The chlorine is provided to the reaction mixture in a mole percent, based upon the total moles of chlorine and methyl chloride in the mix, which ranges from about 16 mole percent to about 2 mole percent.
