Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE PREPARACION DE DISULFUROS Y POLISULFUROS ORGANICOS MEDIANTE REACCION DE AZUFRE CON UN MERCAPTAN O UN POLISULFURO DE RANGO INFERIOR EN AZUFRE PARA TRANSFORMARLO EN UN POLISULFURO DE RANGO SUPERIOR, O TAMBIEN POR REACCION DE UN MERCAPTAN CON UN POLISULFURO ORGANICO DE RANGO ELEVADO EN AZUFRE PARA TRANSFORMARLO EN POLISULFURO DE RANGO INFERIOR EN AZUFRE EN PRESENCIA DE UN CATALIZADOR EN FORMA DE RESINA DE FUNCION BASICA. ESTE PROCEDIMIENTO SE CARACTERIZA POR QUE LA RESINA UTILIZADA ES UN POLIESTIRENO-DIVINILBENCENO (PSDVB) DE FORMULA GENERAL (I), DONDE: A) ES EL SOPORTE RESINA PSDVB, Y L ES UN RADICAL ORGANICO LINEAL DE LONGITUD IGUAL O SUPERIOR A LA DEL RADICAL METILENO (- CH 2 -).
