Abstract

PURPOSE: To prepare the colorless, high-purity titled compound in high yield, by the nitrilation and catalytic reduction of a product obtained by contacting a preliminary deaerated higher fatty acid with NH3-H2 mixed gas extracted from the following catalytic reduction process.
CONSTITUTION: A fatty acid stored in the storage tank 8 is deaerated in a deaerating tower 9, and contacted in a packed column 7 with NH3-H2 mixed gas taken out from the catalytic reduction reactor 5 to obtain a mixture of a higher fatty acid and the ammonium salt of the higher fatty acid. The mixture is separated from H2 gas, and sent to the nitrilation reactor 1, in which it is reacted with NH3 supplied from the tank 2 to afford a nitrile. H2 gas supplied from a hydrogen bomb and the one separated from the packed column 7 and purified by removing NH3 in the washing column 10 and liquid impurities in the cyclone 11, is made to react with the nitrile in a catalytic reduction reactor 5 to afford the objective secondary amine, which is recovered from the bottom of the reactor 5.
