General description

Dodecylpyridinium chloride is a cationic surfactant.

Application

Micellization characteristics of dodecylpyridinium chloride have been studied. Properties such as molar conductivity, surface tension and surface adsorption parameters has been reported. A non-ionic-cationic mixed system composed of Triton X-100 and dodecylpyridinium chloride respectively was studied for its clouding behavior.

The interaction of α-cyclodextrin (α-CD) with ten ionic surfactants (S) in water was systematically examined using isothermal titration calorimetry. The S comprised cationic and anionic head groups while the hydrocarbon alkyl chain length varied from eight to fourteen carbon atoms.

Organoclays have been applied as efficient adsorbents for pharmaceutical pollutants from aqueous solution. In this work, dodecylpyridinium chloride (C12pyCl) and hexadecylpyridinium chloride (C16pyCl) cationic surfactants were used for the preparation of organobentonites destined for diclofenac sodium (DFNa) adsorption, an anionic
