The H_ acidity function in ethylene and propylene glycols

The H_ acidity function has been determined for solutions of sodium and lithium glycollates in ethylene and propylene glycols with a series of nitrodiphenyl-amines as indicators. The validity of the H_ function has been established in basic solutions of ethylene glycol but not in propylene glycol. Equilibrium constants have been reported for the ionization of some nitrodiphenylamines in basic solutions of the two glycols. © 1971 CSIRO. All rights reserved.
