Preparation of haloalcohols

Agent for controlling the peach twig borer, Anarsia lineatella, by the confusion technique containing a mixture of E5-decen-1-ol (I), E5-decen-1-yl acetate (II) and Z5-decen-1-ol (III) and Z5-decen-1-yl acetate (IV), the amount of the Z isomers (III) and (IV) being up to 50% by weight, based on the mixture (I) to (IV), and, if required, conventional additives and assistants.

Dien-1-ols of the general formula I ##STR1## where the radicals R.sup.1 to R.sup.7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl of 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxyalkenyl tert-butyl ether of the formula II ##STR2## in the presence of an acidic catalyst at elevated temperatures and essentially at the same time splitting off the tert-butyl protective group, as is 9-hydroxydodec-10-enyl 1-tert-butyl ether which is useful as an intermediate for synthesizing 8,10-dodecadienol.
