Allylic isomerization of dichlorobutenes catalyzed by iron-containing nanoparticles stabilized in polymeric matrices

Iron-containing clusters obtained by the decomposition of iron complexes in a solution-melt of a polymeric matrix exhibit catalytic activity in the isomerization of dichlorobutenes. The activity of the clusters stabilized in the polytetrafluoroethylene and polyethylene matrices depends on the nature of the stabilizing matrix and the content of the metal in it, i.e., on the size and structure of the cluster, and substantially exceeds the activity of supported metals and powders The clusters in the polytetrafluoroethylene matrix are more active than those in polyethylene. The dependence of the catalytic activity on the metal content has an extreme character, and for the polyethylene matrix it achieves a maximum at a metal content of ～10%. In catalysts with this composition, the particle size increases to 4-5 nm, and the distance between them is shortened, on the average, to 10 nm, which leads to interaction of the cluster particles with each other.

PRODUCTION PROCESS FOR 1,2,3,4-TETRACHLOROHEXAFLUOROBUTANE AND REFINING PROCESS

The production process for 1,2,3,4-tetrachlorohexafluorobutane of the present invention is characterized in that 1,2,3,4-tetrachlorobutane is reacted with fluorine in the presence of a solvent containing hydrogen fluoride. The 1,2,3,4-tetrachlorobutane may be obtained by chlorination of 3,4-dichlorobutene-1. Further, the present invention provides as well a process of refining 1,2,3,4-tetrachlorohexafluorobutane obtained in the manner described above. According to the present invention, 1,2,3,4-tetrachlorohexafluorobutane which is useful, for example, as a synthetic raw material for hexafluoro-1,3-butadiene used as an etching gas for semiconductors can industrially efficiently be produced by using 1,2,3,4-tetrachlorobutane which is a by-product of chloroprene and which has so far been disposed.
