Abstract: Preparation of polyalkenyl amine comprises reaction of a component comprising at least a simple unsaturated polyalkene with carbon monoxide and hydrogen to give a hydroformylated polyalkene, and reaction of hydroformylated polyalkene with hydrogen and ammonia or an amine having at least a primary or secondary amino group; where before the above steps, polyalkene or hydroformylated polyalkene is dissolved in a first solvent and the first solvent is replaced by a second solvent.

Abstract: The present invention describes a process for the preparation of triethylenediamine by reacting piperazine over a zeolite catalyst which, in addition to SiO 2 , contains an oxide of at least one further divalent, trivalent or tetravalent metal M, wherein the zeolite has a molar Si/M ratio of >100. In particular, a zeolite of the ZSM-5 type is used. The use of the zeolites permits suppression of the undesired formation of the byproduct 2-ethylpiperazine and hence considerable simplification of the working-up, in combination with high piperazine conversions and a small excess of water.

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: 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.

Abstract: Purification of triethylene diamine (TEDA) comprises crystallization and extraction of the resulting mother liquor with an extraction agent that is at most only slightly miscible with the solvent of the mother liquor but in which TEDA is soluble. Following extraction, the treated mother liquor with reduced TEDA content and/or the extraction agent enriched in TEDA is recycled to the process. A process for the purification of triethylene diamine (TEDA) by evaporation and feeding the TEDA vapor to a liquid solvent followed by crystallization is characterized in that following crystallization of the TEDA the resulting mother liquor is extracted with an extraction agent that is at most only slightly miscible with the solvent of the mother liquor but in which TEDA is soluble. Following extraction, the treated mother liquor with reduced TEDA content and/or the extraction agent enriched in TEDA is recycled to the process.

Abstract: A process for the selective production of acyclic polyalkylene amines involves reaction of diamines with NH3 and monoalkanol amines in the presence of a phosphorous containing catalyst. The catalyst is a thin film catalyst, prepared by coating a metal, plastic or carbon fiber support with at least one phosphorous containing substance. Independent claims are also included for; (1) A process for the preparation of the catalyst by application of at least one phosphorous containing substance onto a metal, plastic or carbon fiber support followed by drying and/or tempering of the support; and (2) The resulting thin film catalyst.
