Synthesis of novel quaternary ammonium surfactants Containing adamantine

Quaternary ammonium surfactants show a high affinity for negatively charged surfaces, making them suitable for industrial applications and as components of consumer products. The major uses of cationic surfactants are as fabric softeners and antistatic agents in laundry detergents. Important industrial applications are related to manufacturing of organomodified clays and biocides. A series of novel quaternary ammonium surfactants containing adamantine were designed and synthesized from 1-adamantanecarboxylic acid. The structures of target surfactants were investigated. Due to the lipophilicity of adamantine, the critical micelle concentration (CMC) and C(20) values of the synthesized quaternary ammonium surfactants re lower than that of conventional quaternary ammonium surfactants.
