Abstract

"PROCESSO DE GERAçãO DE DIóXIDO DE CLORO A BASE DE PERóXIDO DE HIDROGêNIO". Dióxido de cloro é produzido com alta eficiência, em um processo contínuo realizado usando peróxido de hidrogênio como o agente de redução, em um evaporador de vaso único - cristalizador, no ponto de ebulição do meio de reação sob pressão subatmosférica. O meio de reação e mantido sob operação contínua no estado estacionário com uma concentração de cloro residual à medida que não se verificava nenhuma concentração de peróxido de hidrogênio no meio de reação.
