Abstract
PUEDE PREPARARSE ACIDO PROPANON-1,3-DISULFONICO (ACIDO ACETON-DISULFONICO) POR REACCION DE ACIDO CLOROSULFONICO CON ACETONA PREFERIBLEMENTE EN PRESENCIA DE UN DISOLVENTE PARA LOS REACTIVOS, TAL COMO EL CLORURO DE METILENO, AUNQUE ES POSIBLE UNA REACCION SIN DISOLVENTE. LOS REACTIVOS Y LAS CONDICIONES DE REACCION ANTES DE LA SEPARACION DEBEN SER SUSTANCIALMENTE ANHIDROS, PERO PUEDE AÑADIRSE AGUA DESPUES DE LA REACCION PARA SEPARAR EL PRODUCTO COMO UNA DISOLUCION ACUOSA.
