FIELD: chemical industry. SUBSTANCE: method involves removing hexachlorobutadiene by means of reactants forming solutions with hexachlorobutadiene and increasing rate of migration of hexachlorobutadiene from inside of object onto surface thereof. Method allows extent of hexachlorobutadiene distributed in objects under degassing procedure to be reduced. EFFECT: increased efficiency in reducing concentration of hexachlorobutadiene in air inside working rooms. 2 cl, 2 tbl
