Abstract

EL INVENTO ES LA SINTESIS DE DITIOLES Y MAS PARTICULARMENTE LA DE (ALFA), W DITIOLES QUE CONTIENEN DE 5 A 20 ATOMOS DE CARBONO. SEGUN EL INVENTO DICHO PROCESO CONSISTE EN HACER REACCIONAR CON HIDROGENO SULFURADO UN DI (TERCIOALQUILTIO) ALCANO EN PRESENCIA DE UN CATALIZADOR ACIDO SOLIDO. SE OBTIENE SELECTIVAMENTE EL ALCANO DITIOL, Y COMO SUBPRODUCTO, UN TERCIOALQUIL MERCAPTANO QUE PUEDE SER REUTILIZADO EN UN PROCESO CICLICO PARA PRODUCIR EL DI - (TERCIOALQUILTIO) ALCANO DE SEPARACION.
