説明

The following two types of semipolar organoboron surfactants were prepared by esterification of fatty acids with di glycerol borate-ethylene oxide adducts which were made under Lewis acid catalyzed condition.<BR>The bound state between acyl group, polyoxyethylene group and di glycerol borate residue in above surfactants was confirmed by IR, NMR and potentiometric titration analysis.<BR>Average additional moles and distribution of polyoxyethylene groups were suggested by GPC, TLC and potentiometric titration data of di glycerol borate-ethylene oxide adducts.<BR>Addition reaction mechanism of ethylene oxide to di glycerol borate was especially discussed int hese synthetic process.<BR>On the other hand, it was found that type 1 was completely soluble in water and had better surface tension lowering ability than Tween and PEG fatty monoesters.
