Measurement of the quantity of water in organic solvents by infrared absorption an measurement of the dielectric constants; Dosage de l'eau dans les solvants organiques par absorption infra-rouge et mesure des constantes dielectriques

Abstract

Some chemical methods for the analysis of the quantity of water in solvents are first described, their object being the determination of the maximum error for cases where the water content is less than 1 per cent. - The first part of the work consists in describing infrared spectrometry as applied to the analysis of water in carbon tetrachloride, chloroform aniline, acetone and dioxane. A method based on isotopic exchange between heavy and light water is used on the one hand for determining the solubility of water in carbon tetrachloride and on the other hand for establishing standard solutions (sensitivity of the method). - In the second part the dielectric constant of water solvent solutions is measured. A table is presented giving the precision obtained by the two principal methods. These are comparable and further than that the appearance of the spectra suggests an interpretation of the anomalies observed in calibration curves obtained by the dielectric constant method.

Une methode basee sur l'echange isotopique entre l'eau legere et l'eau lourde permet de determiner d'une part la solubilite de l'eau dans le tetrachlorure de carbone et le chloroforme et d'autre part le titre en valeur absolue des solutions etalons (sensibilite de la methode). - Dans une deuxieme partie, on mesure la constante dielectrique des solutions eau-solvant. On dresse un tableau des precisions obtenues par les deux methodes principales. Celles-ci sont comparables et en outre, l'aspect du spectre suggere une interpretation des anomalies observees dans les courbes d'etalonnage tracees par la methode des constantes dielectriques.
