Abstract

Procedimiento para la obtención de di-(N-metil-N-fenil- tiuram)-disulfuro por reacción de N-metil-anilina con disulfuro de carbono en presencia de uno o mas compuestos básicos, seguido de oxidación empleando uno o mas agentes de oxidación convencionales, caracterizado porque N-metil-anilina se hace reaccionar, empleando un emulsionante, con un ligero exceso de disulfuro de carbono en fase acuosa, agregándose en exceso el compuesto básico, una vez terminada la oxidación la mezcla de reacción se acidifica empleando uno o mas ácidos inorgánicos y/u orgánicos, y el producto sólido obtenido se aisla en la forma usual.
