Abstract
"PROCESSO PARA PREPARAR ALDEìDOS, áCIDOS CARBOXìLICOS E/OU ANIDRIDOS DE áCIDO CARBOXìLICO". é descrito um método para produzir aldeídos, ácidos carboxílicos, e/ou anidridos de ácido carboxílico, especialmente anidrido ftálico. De acordo com o citado método, uma corrente gasosa compreendendo um hidrocarboneto aromático e oxigênio molecular é direcionada pelo menos através de um leito de um primeiro catalisador e de um leito de um segundo catalisador em uma temperatura alta, o segundo catalisador estando localizado a jusante do primeiro catalisador na direção do fluxo da corrente gasosa e possuindo uma atividade maior do que a do primeiro catalisador. O material cataliticamente ativo do primeiro catalisador contém pelo menos óxido de vanádio, óxido de titânio, e óxido de antimónio, a razão entre vanádio, que é calculado como V~ 2~O~ 5~, para antimónio, que é calculado como Sb~ 2~O~ 3~, no primeiro catalisador variando entre 3,5:1 e 5: 1. Preferivelmente, trióxido de antimónio particulado possuindo um tamanho de partícula médio de 0,5 <109>m a 5 <109>m é usado como a fonte de óxido de antimónio no primeiro catalisador. O método da invenção permite que sejam obtidos produtos de oxidação desejados com rendimento grande durante períodos de tempo prolongados.
