General Description

1,1,1,3,3-Pentachlorobutane is a chemical compound characterised by the formula C4H7Cl5. As suggested by the name, it has five chlorine atoms and is a chlorinated derivative of butane. This organic substance belongs to the category of Haloalkanes and Haloarenes. Currently, there isn't much specific information about its physical and chemical properties or its applications in public databases, suggesting it's not widely used or studied. Standard safety measures should be applied when handling this compound, given that chlorinated hydrocarbons can be potentially toxic and harmful to the environment.

PROCESS FOR PREPARATION OF 1,1,1,3,3-PENTACHLOROBUTANE

A process for preparation of 1,1,1,3,3-pentachlorobutane comprises reacting carbon tetrachloride and 2-chloropropene, in which the catalyst includes main catalyst and co-catalyst. The said main catalyst is one or more catalysts selected from the group consisting of Fe (II) salt, Fe or Fe (III) salt, co-catalyst is one or more catalysts selected from the group consisting of alkyl phosphites, alkyl phosphates or aryl phosphates. The said process has high yield and selectivity, and the catalyst is conveniently separated from the product.

PROCESS FOR THE PREPARATION OF HALOGENATED HYDROCARBONS WITH AT LEAST 3 CARBON ATOMS IN THE PRESENCE OF A RUTHENIUM COMPOUND

A telomerisation process is described whereby haloalkanes like tetrachloromethane are added to halogensubstituted olefins like 2-chloroprop-1- ene in the presence of a Ru catalyst. The reaction products, e.g. 1,1,1,3,3-pentachlorobutane, can be fluorinated.
