PRODUCTION OF ACYLATED AMINE

PURPOSE:To obtain an acylated amine good in odor and hue in reaction of an amine with a fatty acid by carrying out steaming during and after or after the reaction. CONSTITUTION:Steam is blown into a reaction system during and after or after reaction of an amine expressed by the formula I to III (R is straight-chain or branched chain 8-22C alkyl or alkenyl; R1 is 1-6C alkyl or alkenyl; R2 to R4 are 2-6C aminoalkyl or 2-6C hydroxyalkyl) with a fatty acid expressed by the formula R5COOH (R5 is straight-chain or branched chain 8-22C alkyl or alkenyl) to afford an acylated amine expressed by formula IV to VI (R2' to R4' are respectively acylated aminoalkyl or acylated oxyalkyl obtained by condensing reaction of R2 to R4 with the fatty acid). The reaction is carried out at 100-300 deg.C, preferably 160-220 deg.C temperature and the total amount of the steam blown into the reaction system is preferably 0.01-10kg, especially preferably 0.5-5kg based on 1kg total amount of the amine and the fatty acid.
