Abstract
A method of purifying vinylidene fluoride is provided. The method comprising: contacting a first fluid including vinylidene fluoride as a main component and further including trifluoromethane with a synthetic zeolite 4A, obtaining a second fluid in which the mass ratio of the content of vinylidene fluoride to the total content of the vinylidene fluoride and trifluoromethane is higher than the mass ratio of the content of the vinylidene fluoride to the total content of the vinylidene fluoride and the trifluoromethane in the first fluid.
Claims4
A method of purifying vinylidene fluoride, the method comprising:
- contacting a first fluid, comprising vinylidene fluoride as a main component and further comprising trifluoromethane, with a synthetic zeolite 4A;
- and
- obtaining a second fluid in which a mass ratio of a content of vinylidene fluoride to a total content of the vinylidene fluoride and trifluoromethane is higher than a mass ratio of a content of the vinylidene fluoride to a total content of the vinylidene fluoride and the trifluoromethane in the first fluid.
