(Substituted-quinoline-1-yl) Methylbenzylammonium Chloride: Quaternization Reaction Process, Corrosion Inhibition Behavior, and Calculation Process

Molecules
In this paper, three quinoline-based quaternary ammonium salts were successfully synthesized, with quinoline, 8-hydroxyquinoline, and 8-methoxyquinoline used as raw materials, and benzyl chloride as a quaternization reagent. The as-synthesized quaternary

Quaternary Ammonium Salt-Based Cross-Linked Micelles to Combat Biofilm

, 2019
Due to self-produced extracellular polymeric substances (EPS), biofilms are hard to eradicate by common antimicrobials. Herein, a new quaternary ammonium salt based cross-linked micelle (QAS@CM) was created to combat biofilms.

Turbulence and Cavitation Suppression by Quaternary Ammonium Salt Additives [PDF]

, 2018
We identify the physical mechanism through which newly developed quaternary ammonium salt (QAS) deposit control additives (DCAs) affect the rheological properties of cavitating turbulent flows, resulting in an increase in the volumetric efficiency of ...

Antifungal activity of gemini quaternary ammonium salts

Microbiological Research, 2013
A series of gemini quaternary ammonium chlorides and bromides with various alkyl chain and spacer lengths was synthesized. The most active compounds against fungi were chlorides with 10 carbon atoms within the hydrophobic chain. Among these compounds were few with no hemolytic activity at minimal inhibitory concentrations.

Biological Activity of Quaternary Ammonium Salts and Their Derivatives

Pathogens, 2020
Besides their positive role, microorganisms are related to a number of undesirable effects, including many diseases, biodeterioration and food spoilage, so when their presence is undesired, they must be controlled. Numerous biocides limiting the development of microorganisms have been proposed, however, in this paper the biocidal and inhibitory ...

Quaternary ammonium salt as initiator for vinyl polymerization

Journal of Polymer Science, 1958
AbstractBinary mixtures of amines and alkyl (or aralkyl) chlorides were used as the initiators for the polymerizations of several acrylic monomers and styrene. A parallelism was found between the catalytic actions of the mixtures and their quaternary salt formations.
