METHOD FOR PREPARING HEXACHLOROETHANE Russian patent published in 2003 - IPC

Abstract RU 2217406 C1

FIELD: chemical technology. SUBSTANCE: invention relates to preparing hexachloroethane that is used in production of coolant-113, tablets for degassing, in molding aluminum articles, in preparing deodorants, bactericidal preparations and foaming mixtures. Method involves addition of CCl₄ to powdered aluminum in argon atmosphere. Aluminum is activated with iodine preliminary. The mole ratio aluminum : CCL₄ = 1:8. Process is carried out under atmosphere pressure, at temperature 45 C for 30 min. EFFECT: enhanced yield of end product, reduced amount of waste.
