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: Preparation of E7/Z9-alkadien-1-ols of the formula I (where R = C1-C8-alkyl, R = H or a base-stable hydroxyl protecting group) by reacting an optionally OH-protected 7-hydroxyheptanal II OHC-(CH2)6-OR II with a phosphorus ylide III in which R and R denote a low-molecular weight alkyl group or are connected to one another to give an optionally C1-C4-alkyl-substituted dioxane or dioxolane system and R stands for alkyl, cycloalkyl or optionally substituted phenyl, in a Wittig reaction to give compounds of the formula IV which are converted by the action of acid into the trans 2-nonenal V which is reacted by means of a further Wittig reaction with a phosphorus ylide VI in which R and R have the abovementioned meaning, to give the E7/Z9-alkadienols which are obtained from the reaction mixture in a manner known per se.

Abstract: The present invention provides a process for preparing dinitrotoluene, comprising the steps of a) reacting toluene with nitric acid in the presence of sulphuric acid to give mononitrotoluene, b) separating the reaction product from step a) into an organic phase comprising mononitrotoluene and an aqueous phase comprising sulfuric acid, c) reacting the organic phase comprising mononitrotoluene with nitric acid in the presence of sulphuric acid to give dinitrotoluene, d) separating the reaction product from step c) into an organic phase comprising dinitrotoluene and an aqueous phase comprising sulfuric acid, wherein the reaction product from step a) has a content of toluene of from 3.0 to 8% by weight, based on the organic phase, and a content of nitric acid of from 0.1 to 1.2% by weight, based on the aqueous phase, and the phase separation in step b) is effected in such a way that further reaction of the toluene with the nitric acid is prevented.
