초록
Surface tension as a function of concentration and temperature was measured for aquous solution of sodium N-acyl sarcosinate, RCON(CH3)CH2 COONa, From the intersection points in the (γ-logC) curves, the critical micelle concentration (cmc) was determined at 20, 30, 40, and 50℃. Structural effects on the cmc maximum and the minimum area per molecule at the aquous solution/air interface were discussed. The free energy, enthalpy, and entropy of micellization and adsorption of surfactant solution also were investigated. Numberous investigators have dealt with sodium N-acyl sarcosinates and their applications as wettings, flooding and reducing agents and as corrosion inhibitors.
