Title
(EN) METHOD FOR THE RECYCLING OR DISPOSAL OF HALOCARBONS
(FR) PROCÉDÉ DE RECYCLAGE OU D'ÉLIMINATION D'HYDROCARBURES HALOGÉNÉS
Abstract
(EN)
The present invention relates to a method for recycling and/or disposal of halocarbons, particularly fluorinated alkanes, such as trifluoromethane, by reacting said halocarbons with sulfur trioxide, particularly to form halide sulfonic acids and sulfur dioxide.
(FR)
La présente invention concerne un procédé de recyclage et/ou d'élimination d'hydrocarbures halogénés, en particulier des alcanes fluorés, tels que le trifluorométhane, par réaction desdits hydrocarbures halogénés avec du trioxyde de soufre, en particulier pour former des acides sulfoniques halogénures et du dioxyde de soufre.
