A process for producing EDA from a mixture comprising water (H2O), ethylenediamine (EDA) and N-methylethylenediamine (NMEDA) by feeding the mixture into a rectification column, wherein the rectification column is operated at the top pressure in the range of 5.0 to 7.5 bar.

Separation of n-methylethylenediamine from EDA-containing mixtures

A process for the continuous distillative separation of mixtures comprising morpholine (MO), monoaminodiglycol (ADG), ammonia, water and methoxyethanol (MOE), obtained by reacting diethylene glycol (DEG) with ammonia, wherein ammonia, water, ADG and DEG are removed by distillation and the resulting stream comprising MO and MOE is supplied to a distillation column Kin which at a top pressure of from 20 to 2000 mbar MO, MOE and organic products having a boiling point 128&#xb0; C. (1.013 bar) are removed via the bottom and organic products having a boiling point 128&#xb0; C. are removed overhead, and also MO is removed via a side draw, where Kis equipped with an evaporator for heating the bottoms, into which is fed heating vapor having a pressure of from 1 to 10 bar.

Method for the continuous separation by distillation of mixtures that contain morpholine (MO), monoaminodiglycol (ADG), ammonia, water and methoxyethanol (MOE)

Epoxy resin-based fibre matrix compositions contain alkyl substituted ethylene amines such as dimethyldiethylenetriamine (DMDETA, also dimethyl-1,4,7-triazaheptane), as a curing agent. These curing agents are characterized by a short curing time for a comparatively long processing time, and make it possible to obtain cured epoxy resins that exhibit low brittleness and high tensile strength and have a high glass transition temperature; as a result of which the fibre matrix composition is suitable particularly for use in pultrusion and winding processes.

Epoxy resin-based fibre matrix compositions containing alkyl-substituted ethylene amines

A process for the continuous preparation of 1,2-propylenediamine (1,2-PDA) and dimethyldiethylenetriamine (DMDETA) via reaction of monoisopropanolamine (MIPOA) with ammonia in the presence of hydrogen and a supported heterogeneous hydrogenation catalyst (catalyst), wherein the reaction is effected in the liquid phase at an absolute pressure in the range from 60 to 170 bar.

Process for the continuous preparation of 1,2-propylene diamine (1,2-PDA) and dimethyldiethylene triamine (DMDETA)

A process for the depletion of 2-methoxyethanol (MOE) from a mixture comprising predominantly morpholine (MO) (crude morpholine), wherein crude morpholine is distilled in a distillation column in the presence of an alkali metal compound of the general formula M[RO] (Mis alkali metal cation and R is hydrogen (H), methyl, ethyl, propyl, isopropyl, n-butyl, isobutyl, sec-butyl or tert-butyl), where MO and a compound of the general formula R&#x2014;OH are distilled off and an alkali metal methoxyethoxide of the general formula M[MeOEtO] is obtained in the bottom of the column.

Method for depleting 2-methoxyethanol (MOE)

The present invention relates to a process for hydrogenating nitriles with hydrogen in the presence of a ZrO-supported ruthenium catalyst.

The present invention relates to the use of a porous metal-organic framework material comprising at least one, at least bidentate, organic compound bound to at least one metal ion by coordination, the at least one metal ion, the at least one, at least bidentate, organic compound, or if appropriate a further component, being a coloring component, as sorbent and for permanent color marking of a filter.

Use of porous metal-organic framework materials for color marking of filters

A process for preparing poly-C-C-alkylene glycol mono(meth)acrylic acid esters by reacting (meth)acrylic anhydride with a poly-C-C-alkylene glycol carrying at least one OH group in the presence of abase having a solubility in the poly-C-C-alkylene glycol of not more than 10 g/l at 90&#xb0; C.
