Abstract
Alkyl halides are made by reacting at boiling temperature an alkyl chlorsulphonate Cl-SO2-O-R with excess hydracid HX in the form of an aqueous solution, X being chlorine, bromine, or iodine, and R being an alkyl radicle having three or more carbon atoms, that may be unsaturated, and may contain one or several halogen atoms. The alkyl chlorsulphonate may be obtained from sulphuryl chloride and the corresponding alcohol and used without isolation. In an example, polymethylene chlorobromides of the formula Cl.(CH2)nBr, where n is a number from 3 to 10, are obtained from the chlorosulphonates Cl.SO3(CH2)nCl by boiling with hydrobromic acid. The alkyl chlorosulphonates are obtained by the action of sulphuryl chloride on the alcohols ROH or halogen substituted derivatives thereof. The Specification as open to inspection under Sect. 91 also describes the preparation of methylene chloride, chlorobromomethane, and chloroiodomethane from chloromethyl chlorsulphonate and hydrochloric, hydrobromic, and hydriodic acids respectively, and of 1-chloro-2-bromo-ethane and 1-chloro-2-iodoethane from b -chloroethyl chlorsulphonate and hydrobromic or hydriodic acids respectively. This subject-matter does not appear in the Specification as accepted.
