Abstract
Process for obtaining chloromethanes by thermal chlorination, characterized by mixing chlorine with chnclm, where n = 1 to 4 and m = 4 - n and possibly inert gas and/or gaseous chlorine hydride at a pressure of 2 to 25 absolute atmospheres, in one quantitative ratio such that the volumetric ratio of the chlorine in the total gas mixture is 10% to 50%, and, referred to the sum of the volumetric proportions of the chlorinable components, is at least 14%, of which it is heated said gas mixture entering the reactor in a thin tube at a passing speed of at least 3 m/s with a heat transfer medium of 270º to 400ºC passing around the tube, medium whose temperatures higher and more low do not differ from each other within the circuit by more than 40º c, and is reacted, maintaining a gas temperature tip from 330ºC to 600º c, the mixture of gases leaving the reactor being conducted to a preparation facility and separation.
