The present invention relates to a process for purification of a mixture comprising water, N-alkyl-hydroxylammonium salts and some byproducts wherein from the mixture water and byproducts are distilled off until the purity of N-alkyl-hydroxylammonium salts in the residue is 95% or higher and additionally keeping the water content during and after the distillation≥40 wt.-% according to the residue.

Process for the purification of a mixture comprising N-alkyl-hydroxylammonium salts

The invention relates to a process for preparing certain amines, wherein, in a first step, a corresponding amino alcohol is reacted with a suitable carbonyl compound and then, in a second step, the intermediate obtained in the first step is reacted with a suitable amine component to form the desired amine.

Method for synthesizing amines

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.
