摘要： The invention relates to a process for the partial or complete separation of a mixture comprising hydrogen chloride and phosgene, possibly solvents and possibly low boilers and inerts as are typically obtained in the preparation of isocyanates by reaction of amines with phosgene, which comprises firstly carrying out a partial or complete condensation of phosgene, then a distillation or stripping step in a column to remove the hydrogen chloride from the bottom product phosgene and subsequently a scrub of the top product hydrogen chloride by means of the process solvent to absorb the phosgene in the process solvent. An after-purification by means of adsorption on activated carbon or by another suitable method can subsequently be carried out to remove solvent residues.

摘要： 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.
