Cyclohexylamine is recovered from an aqueous solution of cyclohexylamine sulphate by a process comprising adding sodium hydroxide to the aqueous solution in such an amount that the separating aqueous phase contains at least 9.5% by weight of sodium hydroxide and withdrawing this phase from the two-phase system formed, the cyclohexylamine remaining as the organic phase. Preferably the sodium hydroxide is added as an aqueous solution and sufficient is added to produce an aqueous phase containing at least 30% by weight of the sodium hydroxide.
