Physicochemical Properties of Dodecylammonium Picrate
A novel surfactant, dodecylammonium picrate (DDAP), was synthesized and its crystal structure was determined by X-ray diffraction analysis. DDAP physicochemical properties were examined by spectral (infrared and nuclear magnetic resonance), thermal, microscopic and condumetric studies. The results revealed influence of counterion specificity on thermal solid-state transitions and solution properties: the Krafft point, the aqueous solubility, the critical micelle concentration, the degree of counterion binding and thermodynamic parameters of micellization.
