Abstract

a presente invenção se relaciona a um processo para preparar anidrido ftálico por oxidação de fase gasosa de hidrocarbonetos aromáticos, em que uma corrente de gás compreendendo pelo menos um hidrocarboneto aromático e oxigênio molecular é continuamente passada por um catalisador termorregulado e o fornecimento do pelo menos um hidrocarboneto aromático ao catalisador é temporariamente interrompido após colocar o catalisador na corrente.
