Abstract

PROCEDIMIENTO PARA LA PREPARACION DE UN AGENTE DE VALORACION, A PARTIR DE LA REACCION DE UNA AMINA, DIOXIDO DE AZUFRE Y YODO, UTILIZABLE PARA LA DETERMINACION DEL CONTENIDO DE AGUA EN SUSTANCIAS SOLIDAS O EN LIQUIDOS. CONSISTE EN DISOLVER CANTIDADES DE 0,1 HASTA 10 MOLES DE UNA AMINA ALIFATICA, QUE PRESENTA EVENTUALMENTE 1, 2 O 3 ATOMOS DE OXIGENO, DE 0,1 HASTA 10 MOLES DE DIOXIDO DE AZUFRE, Y DE 0,01 HASTA 3 MOLES DE YODO, EN UN ALCOHOL ANHIDRO DE BAJO PESO MOLECULAR CON EXCLUSION DE LA HUMEDAD DEL AIRE, ESTANDO REFERIDAS LAS MENCIONADAS CANTIDADES MOLARES EN CADA CASO A UN LITRO DE SOLUCION Y ESTANDO COMPRENDIDA LA PROPORCION MOLAR DE AMINA A DIOXIDO DE AZUFRE DESDE 0,5:1 HASTA 1,3:1. COMO AMINA ALIFATICA SE UTILIZA UNA AMINA ACICLICA PRIMARIA CON 2 A 6 ATOMOS DE CARBONO.
