Sažetak
The novel catanionic surfactant, hexadecyltriammonium dodecyl sulfate, was prepared from the equimolar aqueous solutions of cationic, hexadecyltrimethylammonium bromide, and anionic, sodium dodecyl sulfate, surfactants. The composition, structure, morphology and thermal behavior of new compound were determined by chemical, X-ray diffraction, IR and proton NMR spectral analyses, differential scanning calorimetry, thermogravimetry and polarizing microscopy. The thermal behavior of solid crystalline CTADS is rather complex because of its polymorphism, thermotropic mesomorphism and coexistence of ordered and disordered phases below the melting temperature.
