Abstract

Procedimiento para la obtención de un reactante para la determinación cuantitativa de agua, cuyo reactante contiene dióxido de azufre y un acetato de metal alcalino anhidro en un alcohol alifático inferior anhidro como disolvente, junto con una solución de titración conteniendo iodo, caracterizado porque el acetato de metal alcalino anhidro se hace reaccionar con dióxido de azufre en 2-metoxietanol libre de agua y de oxigeno, o con una mezcla de 2-metoxietanol y metanol libre de agua y de oxigeno, en una proporción en volumen de como mínimo 10: 90 como disolvente.
