Allgemeine Beschreibung

Benzyldimethyltetradecylammonium chloride (BTDACl), a quaternary ammonium compound, is a cationic surfactant. It is utilized as phase transfer catalyst in organic reactions. Kinetics, thermodynamics and reaction mechanism of biosorption of benzyldimethyltetradecylammonium chloride (tetradecyl benzyl dimethyl ammonium chloride) onto activated sludge has been studied.

Anwendung

Benzyldimethyltetradecylammonium chloride (Dimethylbenzyltetradecylammonium chloride) may be used in the following studies:
  • Spectrophotometric determination of cobalt(II).
  • Preparation of mixed micelle with tetradecyltrimethylammonium (TTAB) and tetradecyltriphenylphosphonium bromides.
  • Preparation of modified analcime zeolite, used in the trace determination of cadmium.
  • As a phase transfer catalyst in the preparation of 2,3-epoxy-1-phenyl-3-aryl-1-propanones.

Benign strictures at the cardia are troublesome for patients and often require repeated endoscopic treatments. Paclitaxel can reduce fibrosis. This study evaluated a biodegradable paclitaxel-eluting nanofibre-covered metal stent for the treatment of benign cardia stricture in vitro and in vivo.

In this study the sorption of phenol and 4-chlorophenol on pumice modified with the cationic surfactants hexadecyltrimethyl ammonium bromide (HDTMA) and benzyldimethyl tetradecylammonium chloride (BDTDA) was investigated. Experimental studies indicate that HDTMA-pumice and BDTDA-pumice have the capability to remove phenol

Spectrophotometric determination of cobalt(II) was accomplished with vanillilfluorone (VF) in the presence of dimethylbenzyltetradecylammonium chloride (Zephiramine, Zep). In the determination of cobalt(II), Beer's law was obeyed in the range of 24-470 ng/ml, with an effective molar absorption coefficient (at 575
