Abstract:
A process for stabilizing monoalkyl-substituted diaminocyclohexanes, the process containing: adding a reductant and optionally water to a first composition containing a monoalkyl-substituted diaminocyclohexane and optionally water to obtain a second composition, wherein the second composition contains the reductant, the monoalkyl-substituted diaminocyclohexane and additionally at least 0.05% by weight of water based on the total weight of the second composition.
