FIELD: chemistry.
SUBSTANCE: invention discloses a method of producing an azeotropic composition containing fluorohydroolefin with 3-8 carbon atoms via dehydrofluorination of a fluorine-containing hydrocarbon. The invention also discloses methods of separating fluorohydroolefins from fluorine-containing hydrocarbons and from hydrogen fluoride.
EFFECT: invention enables to obtain fluorohydroolefins without using a catalyst.
