<p>Higher-molecular alkyl halogenides and primary halogen-substituted alcohols are produced by reacting the hydracid of chlorine or bromine and monomeric or polymeric formatin with an ethylenic hydrocarbon containing at least eight carbon atoms and having no double-linked carbon atom in the end position. The reactions can be written as follows: <FORM:0671376/IV (b)/1> in which R, R1, R1, and R11 represent straight or branched alkyl radicals or hydrogen providing at least six carbon atoms are present and that neither both R and R1 nor both R1 and R11 are hydrogen atoms; and in which X represents a halogen atom. At the same time some of the halogen acid reacts with the olefine as follows: <FORM:0671376/IV (b)/2> The alkyl halides formed in this way may be subjected to Friedel-Craft's reaction to give higher-molecular alkyl-benzenes or alkylnaphthalenes or like alkyl-aromatic hydrocarbons. The halogen - substituted primary alcohols formed may be used in the production of anionactive detergents of the sulphonated fatty alcohol class. When esterified with halogen hydracids to p dihalogenides X-CnH2n-CH2-X they may be used as constituents of cationactive detergents belonging to such classes as quaternary ammonium salts and alkyl pyridinium salts. The higher-molecular halogen-containing primary alcohols on losing one molecule of halogen hydracid give primary ethylene alcohols CnH2n-1-CH2OH which are useful in the preparation of perfumes and detergents. These unsaturated ethylene alcohols may be hydrogenated to give saturated alcohols which are suitable for the same purposes. In the examples (a) octyl chloride and primary chlorononanol are prepared from octylenes, and (b) dodecyl chloride and chlorotridecanol are prepared from dodecylenes. The chlorononanol formed in (a) is treated with alcoholic potash to give primary nonanol and the chlorotridecanol formed in (b) gives tridecanol with the same treatment.
