Abstract

"PROCESSO PARA A PREPARAçãO DE DISSULFETOS ORGâNICOS, E, USO DO DISSULFETO ORGâNICO". A presente invenção refere-se a um processo para a preparação de dissulfetos orgânicos por oxidação de mercaptans com enxofre dissolvido em um dissulfeto orgânico usando-se uma amina como catalisador, em que os mercaptans são usados como "corrente de mercaptan bruto" proveniente de uma reação de álcoois com sulfeto de hidrogênio sobre um catalisador adequado para síntese de mercaptan. Além disso, a invenção refere-se ao uso dos dissulfetos orgânicos para a preparação de ácidos alcanossulfónicos.
