Abstract
LA INVENCION SE REFIERE A LA FABRICACION DEL DIMETILDISULFURO A PARTIR DEL METILMERCAPTANO Y DEL AZUFRE. EL PROCESO SEGUN LA INVENCION SE CARACTERIZA POR EL HECHO DE QUE COMPRENDE: (A) UNA PRIMERA ZONA DE REACCION EN LA QUE EL METILMERCAPTANO Y EL AZUFRE SON INTRODUCIDOS SE LES HACE REACCIONAR EN PRESENCIA DE UN CATALIZADOR, (B) UNA ZONA DE DESGASIFICACION EN LA QUE LOS PRODUCTOS QUE SALEN DE LA PRIMERAS ZONAS DE REACCION SON TRATADOS PARA ELIMINAR AL MENOS PARCIALMENTE EL HIDROGENO SULFURADO DISUELTO, Y (C) UNA SEGUNDA ZONA DE REACCION EN LA QUE LOS PRUDUCTOS QUE SALEN DE LA ZONA DE DESGASIFICACION SE LES PONE EN CONTACTO CON UN CATALIZADOR.
