Abstract
An object is to provide a method for producing 1,1,1,4,4,4-hexafluoro-2-butene with high efficiency, which is suitable for a flow reaction, and cis-1,1,1,4,4,4-hexafluoro-2-butene can be efficiently obtained when isomerization of hexafluoro-1,3-butadiene is conducted using a catalyst and the resultant mixture is successively subjected to catalytic hydrogenation to produce cis-1,1,1,4,4,4-hexafluoro-2-butene, wherein the whole process is performed by a flow catalytic reaction.
Claims22
A method for producing cis-1,1,1,4,4,4-hexafluoro-2-butene from hexafluoro-1,3-butadiene, wherein cis-1,1,1,4,4,4-hexafluoro-2-butene is produced through hexafluoro-2-butyne by a flow catalytic reaction.
A method for producing hexafluoro-2-butyne from hexafluoro-1,3-butadiene, wherein isomerization of hexafluoro-1,3-butadiene is conducted by a flow catalytic reaction.
A method for producing cis-1,1,1,4,4,4-hexafluoro-2-butene by subjecting hexafluoro-2-butyne to catalytic hydrogenation reaction, wherein the reaction is conducted by a flow reaction, and wherein the catalyst for the hydrogenation comprises at least one metal selected from palladium, copper, silver, and bismuth and a carrier having the metal supported thereon.
