Benzyldimethylhexadecylammonium (BDHA) based double-chained metallosurfactants, BDHA2[MCl4] (M = Mn, Co, Ni, Cu, Zn) were synthesized and characterized by elemental anal., NMR (1H, 13C) and FT-IR spectroscopy. Thermal gravimetric anal. showed more stability of synthesized metallosurfactants as compared to the precursor benzyldimethylhexadecylammonium chloride. Their critical micelle concentration (cmc) values were determined in aqueous medium by using surface tension, conductivity and fluorescence spectrophotometric methods. The cmc values follow the order: Mn > Co ≈ Cu ≈ Zn > Ni. The thermodn. parameters of micellization were computed from the temperature dependence of the cmc. These metallosurfactants have surprisingly low counterion binding constant values (0.25 to 0.31) compared to benzyldimethylhexadecylammonium chloride and other ionic surfactants. Compensation of enthalpy and entropy of micellization of BDHA2[MCl4] metallosurfactants is observed in the aqueous medium. Adsorption behavior of BDHA2[MCl4] metallosurfactants was assessed by calculating surface excess and area per mol. at the air/water interface. Dynamic light scattering and zeta potential measurements revealed the small average hydrodynamic diameter of highly stable micelles of the metallosurfactants in aqueous solutions (hydrodynamic diameter = 4-6 nm with polydispersity index <0.13 and zeta potential >+45 mV). Transmission electron microscope measurements also showed the presence of small spherical micelles. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).
N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride
