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, ...
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 ...
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 ...
