VOLUMETRIC DETERMINATION OF ACETONE.

The Determination of Acetone

In the determination of P-oxybutyric acid through oxidation to acetone by the Shaffer bichromate method’ with subsequent estimation of the acetone by Messinger’s iodimetric titration,” difficulty was experienced in obtaining the t,heoretical amount of acetone from known amounts of pure P-oxybutyric acid. It was suspected that either the Messinger titration was inaccurate or that the acetone was...

Volumetric determination of columbium.

The quantitative determination of columbium based on reduction by amalgamated zin c and reox idation with potassium permanganate has, in general, produced results that lack both accuracy and precision. A study of t he various factors involved indicates that essential conditions requ ire adequate duration of reduction in t he presence of an excess of zinc and a proper concentration of both acid ...

Determination of the Acetone Bodies in Blood.*

Comparatively few methods are available for the determination of the acetone bodies in blood. Marriott (1913-14, b) has described a method by which the nephelometric technique described by him (1913-14, a) could be applied to the determination of these substances in blood. Scott-Wilson’s reagent was used in this determination (Scott-Wilson, 1911). Marriott used this method in studying the relat...
