Abstract
"PROCESSO PARA A PREPARAçãO DE UM COMPOSTO CONTENDO UM ANEL BENZENO 2,4,6- TRIIODADO". A invenção proporciona um processo melhorado para a preparação de um composto contendo um anel benzeno 2,4,6- triiodado, compreendendo esse mencionado processo reagir um ácido 5-aminobenzóico 2,4,6-não substituído ou um derivado do mesmo com um agente de iodação de halogeneto de iodo, em um meio aquoso de reação, caracterizado pelo fato de que o agente de iodação é adicionado a um meio aquoso contendo o ácido 5-amino benzóico, ou um seu derivado, em duas diferentes faixas de temperatura: (A) uma ou mais primeiras porções do agente são adicionadas a uma temperatura na faixa de 40 a 70° C e em seguida uma ou mais segundas porções do agente são adicionadas a uma temperatura na faixa de 75 a 95° C ou, (B) uma ou mais primeiras porções do agente são adicionadas a uma temperatura na faixa de 75 a 95° C e em seguida uma ou mais segundas porções do agente são adicionadas a uma temperatura de 60 a 70° C.
