Differential Kinetic Determination of Ketone Mixtures

Abstract

A method for the determination of binary ketone mixtures is described which is based on the differential reaction rates of ketones in a large excess of hydroxylamine hydrochloride. The reactions are followed with a pH stat. For mixtures containing ca. 10^?5 moles of ketone, a relative error and precision of 1% was obtained if the rate constants differed by a factor of 5, and 3% if the rate constants differed by 3.
