[PDF] Synthesis and antibacterial activities of new quaternary ammonium

What is the quaternization of amines and phosphines with haloalkanes?

The quaternization of amines and phosphines with haloalkanes has been loiown for many years, but the development of ionic liquids has resulted in several recent developments in the experimental techniques used for the reaction.

Which reaction can synthesise quaternary amines?

The reaction which can synthesise the quaternary amines was initially known as Menshutkin reaction but now it is regarded as quaternization Quaternary amines are unreactive for most of the electrophiles, nucleophile, oxidants, and acids but it forms quite stable compounds with nucleophiles.

What are quaternary amines used for?

There are a lot of uses of quaternary amines such as consumer applications like antimicrobial detergents, hair conditioners, fabric softeners, and inactivating enveloped viruses; the recent example of SARS-CoV-2 can also be considered. The preparation or synthesis of quaternary amines is called quaternization.

How do chloramines degrade quaternary amines?

Abstract. Experiments suggest that the pathway may involve quaternary amine degradation by amidogen or chloramino radicals formed from chloramines. Quaternary amines are significant constituents of consumer products, including shampoos, detergents, and fabric softeners. Although quaternary amines may be removed by sedimentation during wastewater...
