Abstract
A series of three homologous pure nonionic surfactants, all mono esters of tri(ethylene glycol), were synthesized. The ester surfactants varied in carbon chine length. The surfactant was characterized by determining surface properties of their solutions, including surface tension, critical micelle concentration, effectiveness (πcmc), efficiency (PC20), maximum surface excess (Γ max ), and minimum surface area (A min ). Standard free energies of micellization and adsorption were calculated. Solubilization behaviors of the synthesized surfactants were measured towards paraffin oil as solubilized material using light transmission technique. Base-catalyzed hydrolysis was investigated by using tensiometry.
