    摘要： A method for producing 1,5-pentanediamine in a free form in a simple manner with efficiency is provided. The method for producing 1,5-pentanediamine in a free form from a salt of 1,5-pentanediamine includes an adsorption step of adsorbing 1,5-pentanediamine in a free form on a column of an ion exchange resin by passing a solution of salt of 1,5-pentanediamine through the column of the ion exchange resin; and an elution step of eluting a solution of the 1,5-pentanediamine in a free form from the ion exchange resin by passing an eluent solution through the column of the ion exchange resin on which the 1,5-pentanediamine in a free form is absorbed.

    摘要： The invention relates to a method for producing trans-enriched MDACH, characterized in that an MDACH starting mixture is distilled in the presence of an auxiliary agent. Trans-enriched MDACH is distilled, and - the auxiliary agent is an organic compound with o a molar mass of 62 to 500 g/mol, o a boiling point which lies at least 5 °C above the boiling point of cis,cis-2,6-diamino-1-methylcyclohexane, wherein each of the boling points is based on a pressure of 50 mbar, and o 2 to 4 functional groups which independently of one another are an alcohol, primary, secondary, or tertiary amino group, - the MDACH starting mixture contains 0 to 100 wt.% 2,4-diamino-1-methylcyclohexane (2,4-MDACH) and 0 to 100 wt.% 2,6-diamino-1-methylcyclohexane (2,6-MDACH), based on the total quantity of MDACH (= 2,4- and 2,6-MDACH) contained in the MDACH starting mixture, the MDACH starting mixture containing both trans- as well as cis-isomers, and - trans-enriched MDACH is a mixture containing 0 to 100 wt.% 2,4-MDACH and 0 to 100 wt.% 2,6-MDACH, based on the total quantity of MDACH contained in the mixture. The ratio of trans-isomers in the mixture to the total quantity of MDACH contained in the mixture is higher than the ratio of trans-isomers in the MDACH starting mixture to the quantity of MDACH contained in the MDACH starting mixture.
