  1,3-Diaminocyclohexanes of the general formula (I) are suitable for removing carbon dioxide from fluid streams where the radicals R are each, independently of one another, C 1-4 -alkyl; and n is an integer from 0 to 3. The amino groups of the 1,3-diaminocyclohexane are preferably arranged in trans position relative to one another in the plane of the cyclohexane ring. Absorption media for removing carbon dioxide from fluid streams comprise a) a 1,3-diaminocyclohexane of the general formula (I) and b) optionally at least one tertiary amine and/or a sterically hindered primary or secondary amine. In a process for removing carbon dioxide from fluid streams, the absorption medium is brought into contact with a fluid stream.

  In a process for discriminating cis- and trans-1,3-diaminocyclohexanes, a mixture of cis- and trans-1,3-diaminocyclohexanes is reacted with carbon dioxide or a reactive carbonic acid derivative and the urea of the cis-1,3-diaminocyclohexane, which can be separated off by means of a mechanical separation method, is obtained selectively. 4-Methylcyclohexane-1,3-diamine and/or 2-methylcyclohexane-1,3-diamine having a trans content of 99 mol % or more are obtainable in this way.

  The present invention relates to amine-based curing agents for epoxy resins with low tendency to the formation of carbamates. In particular the invention relates to methylcyclohexyl diamine based adducts which are particularly suitable for the curing of epoxy resins in the presence of humidity, e.g. flooring applications, because of their low tendency to the formation of carbamates (blushing). Accordingly, the invention relates to a process for the preparation of a cured epoxy resin by curing a curable composition comprising an epoxy resin and an adduct at a curing temperature in the range of 0°C to 100°C, wherein the adduct is formed by reacting methylcyclohexyl diamine with a diglycidyl ether diol, and wherein the composition is exposed to humidity at least least part of the initial 24h time period of the curing starting with the time mixing epoxy resin and adduct of the composition. The invention also relates to a hardener component, comprising a diluent and a methylcyclohexyl diamine based adduct,wherein the diluent is selected from the group consisting of benzyl alcohol, bisphenol A, and alkyl substituted phenols.
