Abstract:Three novel starch derivatives with antibacterial properties are synthesized through a rather simple multistep synthesis route. In a first step, sodium periodate oxidation of the hydroxyl groups (C2–C3) of starch yields a di‐aldehyde structure, which is used to attach N,N‐dimethylbenzylamine by Schiff base formation. Then, the amino groups of aminated starch are quaternized with three different ammonium salts (4‐bromobutyl‐pyridinium bromide, 4‐bromobutyl‐benzalkonium bromide, and 4‐bromobutyl‐quinolinium brom… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
