摘要: A process to increase the fraction of trans-isomers of a di-amino-compound selected from 2,4-diamino-1-methylcyclohexane, 2,6-diamino-1-methylcyclohexane or mixtures thereof, and comprising trans-isomers having the two amino groups of the di-amino compound in trans position to the cyclohexane ring as well as cis-isomers having the two amino groups in cis position to the cyclohexane ring wherein a solution comprising the di-amino-compound and an auxiliary compound with at least one hydroxy group having a molecular weight of at maximum 1000 g/mol is prepared, the temperature of the solution is decreased until a suspension comprising crystals is obtained, the crystals are separated from the suspension, and a liquid comprising a trans-enriched di-amino-compound with an increased fraction of trans-isomers is obtained.
