Abstract: The invention relates to a method for the production of a salt-free aqueous hydroxylamine solution by distilling an aqueous solution of an hydroxylammonium salt and a base in a plate column having at least two mechanical plates. The invention is characterized in that packings or structured packings are placed above at least one of the plates of the plate column along the cross section of said column.

Abstract: Process for recovering cyclododecatriene (CDT) from a solution containing CDT and high boilers such as deactivated catalyst and polymers, which includes feeding the solution into a preheater and heating it, subsequently depressurizing it through a downstream pressure maintenance device and feeding the resulting two-phase mixture into a helical tube evaporator and there reducing the CDT content of the liquid phase by partial evaporation and discharging a gaseous product stream having an increased concentration of CDT.

Abstract: Highly pure triethylenediamine is obtained by a process in which triethylenediamine is freed from high boilers and then the triethylenediamine is vaporized from the mixture thus obtained and is passed into a liquid solvent. The process makes it possible in particular to obtain highly pure solutions of triethylenediamine. Crystallization is generally unnecessary.

Abstract: The invention relates to a method for treating a product stream containing vitamin E acetate, consisting of the following stages: a) the product stream is fed to a thin-film evaporator, falling-film evaporator or flash evaporato r and a stream predominantly containing vitamin E acetate is drawn off as a bottom stream from said evaporator; b) the vapour stream from stage a) is fe d to a partial condensation consisting of at least two stages. The invention also relates to falling-film evaporators for separating substance mixtures, whereby one or more heat exchangers are directly integrated into the vapour chamber of the falling-film evaporator.
