Abstract
PURPOSE: To purify a crude organic amine containing a large amount of alcohol, in a simple process, by distilling the crude organic amine in the presence of safely treatable KOH, to remove the alcohol.
CONSTITUTION: An alcohol-free organic amine is obtained by the distillation of a crude organic amine containing an alcohol as an impurity after addition of ≥1 mole, pref. 2-5 moles of KOH, based on 1 mole of the alcohol, to the crude amine to form potassium alcoholate. The organic amine is the one which can be stably distilled in the presence of KOH. The alcohol is primary, secondary and/or tertiary alcohols. The content of the alcohol in the crude amine is pref. ≤ 30% to prevent the lowering the efficiency of the distillaiton.
