    摘要: Haloalcohols of the general formula IHal--X--OH (I)where X is straight-chain or branched, substituted or unsubstituted alkylene of 4 or more carbon atoms in the chain, which may be interrupted by one or more heteroatoms, and Hal is halogen, are prepared by reacting a diol of the general formula IIHO--X--OH (II)where X has the above meanings, with an aqueous hydrogen halide solution in a water-immiscible organic solvent which is inert under the reaction conditions, at from 50.degree. to 150.degree. C., using an excess of hydrogen halide, based on the diol of the general formula II, of from 10 to 200 mole percent and setting a volume ratio of inorganic phase: organic phase of from 1:2 to 1:50.
