FIELD: polymers, chemical technology. ^ SUBSTANCE: invention relates to processing organochlorine wastes in chemical industry, in particular, to detoxifying polychlorobiphenyls. Method involves chemical treatment of polychlorobiphenyls by dechlorination method under atmosphere pressure and preferably at temperature 25-50°C. As reagent method involves using hydroxyl-containing compounds representing polyesters and isocyanate in the mass ratio polychlorobiphenyls : polyesters : isocyanate = 1:(1.25-1.4):(2.6-2.75), respectively. Invention represent an ecologically safety method due to absence of harmful exhausts in atmosphere. ^ EFFECT: improved detoxifying method. ^ 2 cl, 1 tbl, 18 ex |
