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, ...
A Convenient Synthesis of Quaternary Ammonium Gemini Surfactants from Long-chain alkyldimethylamines and Epichlorohydrin
(Georg Thieme Verlag Kg, 2002-12)
Aqueous micellar systems proved to be an excellent reaction medium for the selective synthesis of bis-quaternary ammonium salts 5a-c from epichlorohydrin 2 and long-chain alkyldimethylamines 1a-c, in the presence of the ...
Antibacterial activity of reactive quaternary ammonium compounds in solution and in nonleachable coatings
Antibacterial polymers suitable for coating applications without leaching of the biocidal component have been obtained by UV copolymerization of acrylic resins with acrylic monomers containing quaternary ammonium moieties. ...
Modification of a Brazilian smectite clay with different quaternary ammonium salts
(Sociedade Brasileira de Química, 2010)
In this work, a smectite clay from the State of Paraiba, Brazil, was treated with six different types of ammonium salts, which is an usual method to enhance the affinity between the clay and polymer for the preparation of ...
Synthesis, analysis, cholinesterase-inhibiting activity and molecular modelling studies of 3-(dialkylamino)-2-hydroxypropyl 4-[(alkoxy-carbonyl)amino]benzoates and their quaternary ammonium salts
(Molecular Diversity Preservation International, 2017-12)
Tertiary amines 3-(dialkylamino)-2-hydroxypropyl 4-[(alkoxycarbonyl)amino]benzoates and their quaternary ammonium salts were synthesized. The final step of synthesis of quaternary ammonium salts was carried out by ...
Chemical sensor based on tetradecil ammonium nitrate
The construction and evaluation of an all-solid-state type electrode selective to nitrate based on poly(vinyl chloride) (PVC) as polymeric membrane, diethyl phthalate as plasticizer and tetradecilammonium nitrate (TDAN) ...
Physical, Chemical And Antimicrobial Evaluation Of A Composite Material Containing Quaternary Ammonium Salt For Braces Cementation
(Elsevier Science BVAmsterdam, 2017)
Synthesis and properties of cleavable quaternary ammonium compounds
(Japan Oil Chemists’ Society, 2021-03)
Quaternary ammonium compounds are widely used as antiseptic and disinfectant. It is been a concern that their widespread use will lead to an increase of environmental problems, therefore the development of biodegradable ...
