Paragraph 0115, (2019/06/17)
The present invention provides a method for efficiently producing 1-chloro-1,2-difluoroethylene at low cost. Specifically, the present invention provides a method for producing 1-chloro-1,2-difluoroethylene, including the step of dehydrohalogenating chlorofluoroethane represented by formula (1) CFClX1—CHFX2 wherein X1 and X2 are different from each other and represent H, F, or Cl; and either X1 or X2 is H.

PROBLEM TO BE SOLVED: To provide a method for efficiently and economically producing 1-chloro-1,2-difluoroethylene that can industrially be performed. SOLUTION: The method for producing 1-chloro-1,2-difluoroethylene comprises bringing 1,2-dichloro-1,2-difluoroethane into contact with an alkali aqueous solution in the presence of a phase transfer catalyst to thereby subject 1,2-dichloro-1,2-difluoroethane to dehydrochlorination reaction.

IR Laser-induced Chemistry of some Perhaloethene-Silane Mixtures at Different Single Irradiating Wavelengths

TEA CO2 laser-induced reactions in chlorotrifluoroethene-silane, 1,2-dichlorodifluoroethene-silane, 1,1-dichlorodifluoroethene-silane, and 1,2-dichlorodifluoroethene-trimethylsilane mixtures at medium (4-19 Torr) and in chlorotrifluoroethene-silane and 1,2-dichlorodifluoroethene-silane mixtures at low (1 Torr) pressures can be initiated by irradiation tuned to either perhaloethene or silane.The reaction progress at medium pressure and reaction products at low pressure depend on the particular wavelength employed.The former reactions are assumed to occur through reactive collision of both energized components in the mixture and have been shown to yield mostly tetrafluorosilane, trifluorosilane, hydrogen chloride, and other hydrocarbons.The latter are explained by multiphoton dissociation of the alkene into carbenes, subsequent reactions of these carbenes, and by 1,2-rearrangement of halogen in the transient CFCl=CF* radical produced upon C-Cl bond cleavage of the parent CFCl=CFCl compound.This reaction mechanism is in line with IR multiphoton decomposition of 1,2-dichlorodifluoroethene both in the absence and presence of chlorine and carbon monoxide.
CO2 LASER INDUCED REACTIONS OF CHLOROTRIFLUOROETHENE AND 1,2-DICHLORODIFLUOROETHENE WITH SILANE

Gas-phase reactions in ClFC=CF2 / SiH4 and ClFC=CFCl / SiH4 mixtures at total pressure arround 1 Torr induced by pulsed CO2 laser radiation yield different products depending on whether the single laser irradiating wavelength is tuned to absorption band of olefin or silane.Channels assumed to explain variety of products are multiphoton dissociation of the olefin into carbenes, carbenes recombination and addition to parent olefin, substitution of halogen in transient carbenes by hydrogen of silane, and 1,2-migration of halogen in transient CFCl=CF(.) radical.
