Descrizione generale

N,N-Dimethylbenzylamine is commonly used as a reagent in organic synthesis and also serves as a catalyst in the synthesis of polyurethane foams and epoxy resins. It reacts with Os3(CO)12 to form triosmium clusters. Anodic oxidation of N,N-dimethylbenzylamine has been studied in methanol-tetra-n-butylammonium fluoroborate and in methanol-potassium hydroxide.

Applicazioni

N,N-Dimethylbenzylamine was used in the synthesis of bis[(N,N-dimethylamino)benzyl] selenide. It has been used as catalyst during curing reaction of formulations of diglycidyl ether of bisphenol A and tetrahydrophthalic anhydride.

Functionalized high molar mass chitosan derivatives with increased antibacterial properties were prepared by the reaction of chitosan with different quaternary ammonium salts. Benzalkonium bromide, pyridinium bromide and triethyl ammonium bromide were synthesized by a quaternization reaction between 1,4-dibromobutane and the
