| titleOfInvention | METHOD OF OBTAINING FOUR-CHLORIDE CARBON |
| abstract | 1. A method of producing carbon tetrachloride from a mixture of aliphatic and aromatic hydrocarbons and their halide derivatives by purifying it from solid particles, chlorinating it with chlorine in the gas phase at a temperature of 500-620C and pressure of 160-190 atm, cooling the reaction mass after leaving the reactor, separating carbon tetrachloride - raw material from high-boiling impurities and subsequent purification of the product from low-boiling impurities, mainly chlorine and hydrogen chloride, by rectification with separation of chlorine and hydrogen chloride by rectification and rec chlorine chlorine and chlorinated separated in the first stage of distillation of high-boiling impurities, characterized in that, in order to improve the yield and quality of the target product and simplify the technology, the waste organochlorine production composition, wt.%: Highly condensed hydrocarbons and their halogen derivatives - 2 - 20 Organo-bromine compounds - 0.9 - 3.5 Coke - 0.2 - 1.0 Aliphatic and non-condensed aromatic hydrocarbons and their halo derivatives - The rest (up to 100%) of the raw material is cleaned by fil Treatment, cooling the reaction mass after leaving the reactor is carried out with air or raw carbon tetrachloride and the target product after separation of low-boiling impurities is treated with an aqueous solution of caustic soda and dried with caustic soda. The method according to claim 1, after the separation of low-boiling impurities, the target product is subjected to additional rectification, the distillate is sent for treatment with caustic soda, and the distillation residue is carbon tetrachloride enriched in chlorobromomethanes, returned to the chlorination stage. |
