Determination of betaine and free amine in alkyldimethyl betaine by potentiometric titrations

  • Short Communication
  • Published:
Journal of the American Oil Chemists’ Society

Abstract

Two selective analytical methods are presented for the determination of betaine and free amine contents, respectively, in commercial alkyl dimethyl betaines. Both methods are based on titrations with potentiometric end point detection. The accuracy and precision are discussed.
