Method for synthesizing 4 -halo -1, 1 and 2 -trifluoro -1 -butene (by machine translation)
-
Paragraph 0008, (2020/06/20)
The invention discloses a method for synthesizing 4 -halo -1, 1 and 2 -trifluoro -1 -butene. , Polyhaloethane is synthesized by reaction of chlorotrifluoroethylene with halogen, and then polyhalogenated ethane is reacted with ethylene under the action of a catalyst to synthesize polyhalogenated butane, and finally, 4 - halogenated -1, 1 and 2 -trifluoro -1 -butene are dehalogenated under the action of a reducing agent. The method has the characteristics of simple synthesis method, high product purity and low preparation cost. (by machine translation)
CHEMICAL PRODUCTION PROCESSES AND SYSTEMS
-
Page/Page column 16, (2008/06/13)
Chemical production processes are provided that include reacting a metal comprising olefin to form a conjugated olefin; reacting a heterohalogenated olefin to form a conjugated olefin; reacting a halogenated alkane to form a conjugated olefin; and/or reacting a hydrohalogenated olefin to form a conjugated olefin. Chemical production systems are also provided that can include: a first reactant reservoir configured to house a perhalogenated olefin; a second reactant reservoir configured to house a catalyst mixture; a first reactor coupled to both the first and second reservoirs, the first reactor configured to house a metal-comprising mixture and receive both the perhaloganated olefin form the first reactant reservoir and the reactant mixture from the second reactant reservoir; and a product collection reservoir coupled to the first reactor and configured to house a conjugated olefin.
