Incorporation of poly(Itaconic acid) with quaternized thiazole groups on gelatin-based films for antimicrobial-active food packaging
(MDPI AG, 2021-01)
Poly(itaconic acid) (PIA) was synthesized via conventional radical polymerization. Then, functionalization of PIA was carried out by an esterification reaction with the heterocyclic groups of 1,3-thiazole and posterior ...
Micellar-Improved Synthesis of bis-Quaternary Ammonium Salts by the Epichlorohydrin Route
(Springer Heidelberg, 2003-12)
A convenient procedure for the synthesis of bis-quaternary ammonium salts from long-chain alkyldimethylamines and epichlorohydrin is studied. An improved preparation of bis-quaternary ammonium salts from N,N-dimethyloctylamine, ...
