Abstract: Process for separating triethanolamine continuously by distillation from a mixture of monoethanolamine, diethanolamine and triethanolamine together with ethanolamine ethers and water obtained by reaction of ammonia with ethylene oxide in the liquid phase under superatmospheric pressure and at elevated temperature, in which the mixture is distilled in two stages. The low-boiling fraction and the high-boiling fraction are taken off and discharged in the first stage and the intermediate-boiling fraction comprising >99.4% by weight of triethanolamine and

Abstract: An increase in the cutting hardness of a shaped body comprising a crystalline aluminosilicate is achieved by treating the shaped body with a gas comprising water vapor at from 100 to 600° C. and an absolute pressure of from 0.1 to 10 bar for a period of at least 20 hours, and this shaped body having an increased cutting hardness can be used in processes for chemical synthesis, in particular in a process for preparing triethylenediamine (TEDA) by reaction of ethylenediamine (EDA) and/or piperazine (PIP).

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: Process for the production of at least one alkanolamine by reaction of ammonia with alkylene oxide. The process is carried out in a reactor in the presence of a catalyst and yields mono-, di and/or trialkanolamines. The distribution of the different alkanolamines is regulated by the temperature in the reactor, which is characterized by adjustment of the temperature by regulation of the temperature profile in the reactor.

Abstract: Mono-bridged porphyrin derivatives of formula (I) and their salts are new. R - R = independently alkyl, cycloalkyl, optionally substituted aryl or optionally substituted heteroaryl; R , R = independently H, halo, alkyl, NO2, SO3H, substituted phenyl or CN; Y = R -A-R ; R , R = independently optionally substituted arylene, optionally substituted heteroarylene or optionally substituted cycloalkylene which is optionally interrupted by one or more O, N or S heteroatoms; A = a divalent linear or branched group. Also claimed are metal complexes of formula (II). Z, Z' = independently M, ML or ML L , where M is a group IV, V, VI, VII, VIII, I or II transition metal cation and L and L are independent axial ligands.

Abstract: Preparation of ethyleneamines by reacting monoethanolamine (MEOA) with ammonia in the presence of a catalyst in a reactor (1) and separating the resulting reaction product, where ethylenediamine (EDA) obtained in the separation is reacted in a separate reactor (2) in the presence of a catalyst to give diethylenetriamine (DETA), and the resulting reaction product is passed to the separation of the reaction product resulting from reactor 1.
