PRODUCTION OF N-LONG CHAIN ACYLIMINO DIBASIC ACID OR SALT THEREOF

Title:

PRODUCTION OF N-LONG CHAIN ACYLIMINO DIBASIC ACID OR SALT THEREOF

Document Type and Number:

Japanese Patent JP3544454

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To industrially advantageously obtain the subject compound having a good smell and stability by adding an alkaline agent into a reaction liquid containing an N-long chain acylimino dibasic acid obtained by using a specific reaction solvent and a specific production method.
SOLUTION: This method for producing an N-long chain acylimino dibasic acid or salt thereof, is provided by reacting (B) a compound of formula I [M1, M2 are each H or a cation; (m), (n) are each 1-3] with (C) an acid halide of the formula: RCOX (R is a 5-21C linear or branched alkyl, an alkenyl or the like; X is a halogen) in (A) a reaction solvent containing at least a lower alcohol, and then performing a salt exchange as necessary, or hydrolyzing (E) a compound of formula III obtained by reacting (D) a compound of formula II with the component (C) and then performing the salt exchange as necessary to obtain (F) a reaction solution containing the N-long chain acylimino dibasic acid (salt) of formula IV, then adding (G) an alkaline agent (e.g. sodium hydroxide) into the solution (F) to decompose the lower alcohol in the component (A) and an ester produced from the component (C).
