Abstract: 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 K40 in which at a top pressure of from 20 to 2000 mbar MO, MOE and organic products having a boiling point 128° C. (1.013 bar) are removed via the bottom and organic products having a boiling point 128° C. are removed overhead, and also MO is removed via a side draw, where K40 is equipped with an evaporator for heating the bottoms, into which is fed heating vapor having a pressure of from 1 to 10 bar.

Abstract: 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−] (M+ is 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—OH are distilled off and an alkali metal methoxyethoxide of the general formula M+[MeOEtO−] is obtained in the bottom of the column.

Abstract: 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.

Abstract: 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.
