That is, the present invention provides the process which comprises the steps of adding at least one alkali substance of potassium hydroxide and sodium hydroxide or an aqueous solution thereof to the crude tertiary amine product mixture and distilling the mixture to obtain the tertiary amine having a high quality.
In addition, the tertiary amine has the formula: R.sub.1 R.sub.2 N--R.sub.3, wherein R.sub.1 and R.sub.2 being a saturated or unsaturated hydrocarbon having 6 to 28 carbon atoms, R.sub.3 being a saturated or unsaturated hydrocarbon having 1 to 5 carbon atoms.
