Octadecyl trimethyl ammonium bromide

Almost the same behaviour was found for a higher homologue of this series - octadecyl trimethyl ammonium bromide [70]. A satisfactory agreement between the molecular areas at the CMC evaluated from neutron reflection and surface tension data was obtained too. Two other homologues of this series, dodecyl and hexadecyl trimethyl ammonium bromide, were investigated in [71, 72]. Labelling of blocks of two or four atoms in the surfactant molecules allowed the authors to determine the structure of the adsorbed layer at the CMC. It was shown that the inner part of the carbon chain adjacent to the head group is oriented closer to the...

CBH. The sparingly water soluble compound of heparin with an organic base (BH), such as benzalkonium—e.g., Zephiran (Winthrop) or cetyl trimethyl ammonium bromide or octadecyl amine can be dissolved in ethyl alcohol and mixed with an organic polymer matrix—e.g., collodion in ether and alcohol (4). Such lacquer mixtures are designated CBH. 

Kawasumi etal (1997) modified the montmorillonite clay by octadecyl-amine surfactant via cation exchange process [19]. Shi and Gan (2007) used cetryl trimethyl ammonium bromide for modifying the montmorillonite [20]. Clay can also be modified using hexadecyl trimethyl bromide [21].
