Abstract

High molecular thiosulphuric esters or salts thereof are prepared by treating organic compounds containing exchangeable halogen and aliphatic residues having more than six carbon atoms with salts of thiosulphuric acid. As examples of compounds containing exchangeable halogen and higher aliphatic residues are mentioned: halogenated paraffins, esters having the formula R<1>COOR where R is a residue containing halogen and R<1> a higher aliphatic residue, higher fatty acid amides having exchangeable halogen in the amide group, mono- and poly-halogenated fatty acids and esters, ethers having the formula ROR<1> where R is a residue containing halogen not in the a -position and R<1> a higher aliphatic residue and also halogenated, higher alkyl sulphides. In examples: (1) a -iododecane, prepared from a -dodecanol, iodine and phosphorus, is treated with ammonium or sodium thiosulphate in alcohol; (2) a -chlordodecane, prepared from a -dodecanol and thionyl chloride in benzene, is treated with sodium thiosulphate and a small quantity of sodium iodide. The samples are prepared by reacting sodium thiosulphate with the following compounds: b -bromethyldodecylthioether, (which may be obtained from ethylenebromide and sodium dodecylmercaptan), lauric-N-b -bromethylamide (which may be obtained by treating sodium phthalimide with ethylenebromide, hydrolyzing the product to give bromethylamine and reacting the latter with lauric acid chloride) and stearic-b -chlorethylester. The following components are also specified: a - bromtetradecane, lauric acid methyl-b -chlorethyl amide, dodecyl-b -chlorethylsulphide and dodecyl-b -chlorethylether. Specification 417,965 is referred to. Reference has been directed by the Comptroller to Specifications 390,416 (as open to inspection under Sect. 91 of the Acts), and 397,445.
