Abstract: Dien-1-ols of the general formula I (I) where the radicals R1 to R7 are identical to or different from one another and each is hydrogen or straight-chain or branched alkyl or 1-12 carbon atoms and n is 1-14, are prepared by dehydrating a hydroxylalkenyl tert-butyl ether of the formula II (II) in the presence of an acidic catalyst at elevated tempertures 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.

Abstract: The invention relates to a process for distillatively preparing TDA from a reactant stream comprising TDA, high boilers and low boilers in a dividing wall column in which a dividing wall is disposed in the longitudinal direction of the column to form an upper combined column region ( 2 ), a lower combined column region ( 3 ), a feed section ( 4 ) having a rectifying section ( 5 ) and stripping section ( 6 ), and also a withdrawal section ( 7 ) having a rectifying section ( 9 ) and stripping section ( 8 ), which comprises the following steps: a. feeding the reactant stream ( 13 ) into the feed section ( 4 ) of the dividing wall column ( 1 ); b. drawing off a low boiler fraction via the top of the column ( 11 ); c. drawing off TDA via a side draw ( 14 ) in the withdrawal section ( 7 ) of the dividing wall column ( 1 ); d. drawing off a low boiler fraction via the bottom of the column ( 12 ).

Abstract: The present invention relates to a process for preparing isocyanates by reaction of amines with phosgene in a reactor and subsequent separation of the isocyanate from the reaction mixture leaving the reactor and purification of the isocyanate, wherein the separation and purification of the isocyanate is carried out in a column having a pressure at the top of 1-950 mbar, preferably 5-50 mbar, particularly preferably 10-20 mbar, and a temperature at the bottom of 90-250° C., preferably 120-170° C., particularly preferably 130-150° C., and the pure isocyanate stream is preferably taken off in liquid or gaseous form at a side offtake of the column.

Abstract: 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.
