Aromatic acid chlorides dosage with N-acyl-aminoacids in aprotic solvents by a spectrophotometric method
摘要:
The proposed method consists essentially in the treatment of an aromatic acid chloride solution with certain amounts of N-acyl-aminoacid as reagent. The mechanism of the colored chemical reaction is described here and the concentration of the aromatic acid chloride is determined on the basis of Bouguer-Lambert-Beer law. The results are discussed having in view the electrostatic interactions in the liquid solution in which the reaction takes place. The proposed method offers a high sensitivity, accuracy, easiness and quickness of the operations. (C) 2010 Elsevier B.V. All rights reserved.
