Structural Assignment of Commercial Polyisobutylene Succinic Anhydride‐based Surfactants

Concentration of the surface active agents in industrial products is a common source of error. In order to compare the efficiency of a number of polyisobutylene succinic anhydride (PIBSA) based surfactants, their concentration needs to be determined with a fair degree of accuracy. Industrial samples of the monoethanolamine adduct of PIBSA (PIBSA‐MEA) concentrate were used for chromatographic separation of the functionalized surfactant from the...
