Zusammenfassung
2–10mg der Probe werden in Essigsäure gelöst, mit überschüssigem Reagens versetzt und der Überschuß jodometrisch zurücktitriert. Der maximale Fehler der Ergebnisse beträgt ±2%. Verbindungen, die benachbart zur C=C-Doppelbindung elektronenentziehende Gruppen enthalten, können nicht analysiert werden.
Summary
A micro method for the determination of olefinic unsaturation in organic compounds has been developed. 2–10 mg sample dissolved in acetic acid is reacted with a known excess of N-bromosuccinimide at room temperature and the excess reagent is back titrated iodometrically. The maximum deviation in the results is ±2%. The compounds containing electron withdrawing groups close to the C=C site are not reactive and hence could not be determined by this procedure.
