Identification and Analysis of the Migration of Primary Aromatic Amines from Flexible Food Packaging by High-performance Liquid Chromatography (HPLC)
Background and Objectives: Primary Aromatic Amines (PAAs) are contaminants that can migrate from food flexible packaging. The main origin of these compounds is polyurethane adhesives used in the laminating process of multilayer films. Residual aromatic di-isocyanates of the reaction of adhesive polymerization migrate into the food, and are hydrolyzed to PAAs by the moisture of food. 2,4- and 2,...
متن کاملPreparation of sterically congested 1,3,4-oxadiazole derivatives from N-isocyaniminotriphenylphosphorane, aromatic acids, cyclopentanone and primary amines
Reactions of N-isocyaniminotriphenylphosphorane with cyclopentanone have been studied in the presence of aromatic carboxylic acids and primary amines, proceeds smoothly at room temperature under neutral conditions to afford sterically congested 1,3,4-oxadiazole derivatives by an intramolecular Aza-Wittig cyclization in CH2Cl2 in excellent yields. The structures of the products were deduced from...
متن کاملSpectrophotometric Determination of Hydralazine Using p-Dimethylaminobenzaldehyde
A new spectrophotometric method for the assay of hydralazine hydrochloride in bulk and dosage forms has been developed. The procedure is based on a condensation reaction between alcoholic solution of hydralazine and acidic solution of pdimethylaminobenzaldehyde to generate an instant greenish-yellow coloured product. The hydrazone formed absorbed visible light strongly and optimal detector resp...
متن کاملSpectrophotometric determination of Cilastazol using p-dimethylaminobenzaldehyde
A simple accurate and reproducible spectrophotometric method was established for the estimation of Cilastazol based on the formation of condensation product. The method is based on the formation of yellow colored chromogen, when the drug reacts with p-Dimethylaminobenzaldehyde (PDAB). The colored species has an absorption maximum at 425 nm and obeys Beer's law in the concentration range of 6-10...
متن کاملInteraction of Aromatic Amines with Rat Liver
A number of stable protein adducts formed by the interaction of trace amounts of a metabolite or metabolites of the carcinogenic aromatic amide, N-2-fluorenylacetamide-9J4C, with the nuclear proteins of rat liver have been isolated and purified to constant specific radioactivity with the use of gel titration on Sephadex G-25 and of ion exchange chromatography on carboxymethyl cellulose. Certain...
