Summary

A potentiometric microtitration for the determination of high molecular weight oxiranes is presented. It is based on the reaction of oxiranes with quaternary ammonium bromide and titration with 0.01N perchloric acid. The preferred solvent is acetic acid although small amounts of toluene or chloroform may be used. Epoxy equivalents as high as 370,000 have been determined.

Zusammenfassung

Eine potentiometrische Mikrotitrationsmethode zur Bestimmung hochmolekularer Äthylenoxide wurde vorgeschlagen. Sie beruht auf deren Reaktion mit quaternärem Ammoniumbromid und Titration mit 0,01N Perchlorsäure. Vorzugsweise dient Essigsäure als Lösungsmittel, doch kann man auch kleine Mengen Toluol oder Chloroform verwenden. Epoxyäquivalente bis zu 370 000 wurden bestimmt.
