The reactions of 1,3-bis(α,ω-bromoalkyl)-6-methyluracils with 1,3-bis(α,ω-ethylaminoalkyl)-6-methyluracils or 1,3-bis(bromopentyl)thymine with butylamine afforded pyrimidinophanes containing one or two uracil units and nitrogen atoms in bridging polymethy
New chemical family of [n-CxH(2X+1)Net3][BeT3Me] showing ionic plastic-crystal (x = 4, 5), rotator-crystal (x = 6, 7) and liquid-crystal phases (X = 816)

, p. 1289 - 1298 (2019/09/18)
New ionic liquid crystals of [n-CxH(2x+1)NEt3][BEt3Me] (abbreviated to [CxNEt3][BEt3Me]) were detected for species with even numbers of 8 ˉ x ˉ 16. In contrast, plastic- and rota
Improving Cellulose Dissolution in Ionic Liquids by Tuning the Size of the Ions: Impact of the Length of the Alkyl Chains in Tetraalkylammonium Carboxylate
Meng, Xiangqian,Devemy, Julien,Verney, Vincent,Gautier, Arnaud,Husson, Pascale,Andanson, Jean-Michel
, p. 1749 - 1760 (2017/04/27)
Twenty ionic liquids based on tetraalkylammonium cations and carboxylate anions have been synthesized, characterized, and tested for cellulose dissolution. The amount of cellulose dissolved in these ionic liquids depends strongly on the size of the ions:
Investigation of cationic surfactants and sulfonamides and their nanoparticles as biocides against sulfur reducing bacteria in the petroleum industry
Morsy, Salwa M. I.,Ibrahim, Mohamed M.
, p. 530 - 536 (2014/01/06)
A series of cationic ammonium surfactants (1-3) and sulfonamides (4-5) were synthesized and characterized using elemental analysis and FT-IR spectroscopy. The nanostructures of the synthesized surfactants and sulfonamides as silver and zinc nanoparticles
The Effect of Cationic Detergents on the Spectral Properties of Pontachrome Azur blue and its Metal(III)-complexes - Micell Effect or Ternary Complex Formation ?
Seidel, A.,Hoyer, E.
, p. 299 - 308 (2007/10/02)
The results of studies of the metachromasy effect of pontachrome azur blue and its lakes, preferably with aluminium, and hexadecyl-, tetradecyl-, dodecyl- and decyltriethyl-ammonium-bromide, respectively can be explained on the basis of ternary complex formation.The surfactants can be applied at concentrations far below its critical micelle concentrations thus excluding micelle effects.
Process for preparing 2,2-azobis(2,4-dimethylpentanenitrile)
-
, (2008/06/13)
A process for the preparation of 2,2'-azobis (2,4-dimethylpentanenitrile) with improved filtering and drying characteristics, said process comprising reacting 2-amino-2,4-dimethylpentanenitrile with a metal hypochlorite in the presence of water, a mixture of quaternary ammonium surface active compounds and ionic bromide wherein the equivalent ratio of ionic bromide to surface active compound is 0.4:1-12.0:1 at a temperature of about -10° C. to about 30° C., and recovering 2,2'-azobis(2,4-dimethylpentanenitrile) from the reaction mixture.
