Abstract

"PROCESSO DE PREPARAçãO DE DIáCIDOS ALIFáTICOS A PARTIR DE áGUAS DE LAVAGEM PROVENIENTES DE UM PROCESSO DE OXIDAçãO DE CICLO-HEXANO E CONTENDO PERóXIDOS". A presente invenção refere-se a um processo de preparação de diácidos ou de misturas de diácidos a partir de soluções aquosas provenientes da lavagem de produtos de oxidação de ciclo-hexano. Mais precisamente, a presente invenção consiste em um processo de preparação de diácidos alifáticos a partir de águas de lavagem provenientes de um processo de oxidação do ciclo-hexano e contendo peróxidos, caracterizado em que se efetua sucessivamente as etapas seguintes: a) desperoxida-se pelo menos parcialmente as referidas águas de lavagem submetendo-se as mesmas a uma hidrogenação catalítica a uma temperatura compreendida entre 0°C e 100°C, em presença de pelo menos um metal escolhido no grupo da platina; b) oxida-se com a ajuda de ácido nítrico os produtos contidos nas águas de lavagem após desperoxidação.
