Method for separating an azepine derivative from a mixture containing an amine and an azepine derivative
摘要:
A process for distillative removal of part or all of an azepine derivative (III) selected from the group consisting of aminohexylideneimine, tetrahydroazepine, hexylhexahydroazepine and aminohexylhexahydroazepine from a mixture (II) comprising an azepine derivative (III) and an amine (I) comprises conducting the distillation with an overhead temperature of from 160 to 250° C.
