Abstract
PURPOSE: To obtain the titled compound very favorably without pressurizing, by reacting CH3Cl with Cl under such a pressure as to keep the CHCl3 in the liquid phase at an advantageous reaction rate, and by rectifying and separating the by- product HCl or unreacted CH3Cl under a slowly decreased pressure.
CONSTITUTION: CH3Cl is reacted with Cl in the presence of a radical initiator under such a high pressure as to keep the CH3Cl in the liquid phase at an advantageous successive chlorination rate of K1/K2/K3=1:38:0.076 with a very small amount of CCl4 formed without danger of explosion to give HCl, the unreacted CH3Cl and chlorinated methane. HCl is separated by rectifying the resulting product at a pressure lower than that in the reaction without any additional pressurizing means, and the unreacted CH3Cl is then separated by rectifying at a lower pressure without any additional pressurizing means to separate the chlorinated methane in the decreasing order of the boiling point and to simplify the device.
