Abstract
eliminação do formaldeído em águas usadas por um tratamento de oxidação. a presente invenção refere-se a um processo de tratamento das águas residuais contendo formaldeído. em particular, a invenção refere-se a um processo de tratamento de efluentes líquidos resultantes da fabricação de ácido acrílico ou de acroleína, visando a eliminar o formaldeído presente nesses efluentes. a invenção refere-se, enfim, ao uso da solução aquosa purificada assim obtida em um processo de produção de ácido acrílico por oxidação catalítica de propileno e/ou propano.
