Analysis of methods for determining the critical micelle concentration (CMC) of surface-active substances in E85 fuel

摘要

Five surfactants based on diamine or benzoxazine derivatives were used (10-1000 mg/kg) as an additive to EtOH-modified gasoline. Surface tension and dynamic light scattering were detd. to find CMC. The detn. method had no effect on the CMC values.
