Abstract
Process for obtaining carbon tetrachloride at high temperature and high pressure, in the absence of catalysts, characterized by continuous transformation, in gas phase, in benzene carbon tetrachloride, mixtures of benzene and chlorinated aromatic compounds, mixtures of benzene and of chlorinated aliphatic compounds or chlorinated aromatic compounds and chlorine in stoichiometric ratios or with an excess of chlorine of up to 300%, the reaction components going through the first stage of the process through a preliminary reaction zone which is maintained at temperatures of 62 to 400º c, and then, in the second stage of the process, in a corrosión-resistant reactor, they are transformed into a gas phase in carbon tetrachloride at temperatures of 400º to 800ºC and at pressures of 20 to 200 relative atmospheres.
