Abstract
Patente de Invenção: <B>"MéTODO DE PURIFICAçãO DE PRECURSORES éSTERES DE CARBAZOL DO áCIDO 6-CLORO-ALFA-METIL-CARBAZOL-2-ACéTICO"<D>. Um processo de purificação de um éster de di(alquila C~ 1~-C~ 6~) do ácido (6-cloro-2-carbozolil)metil-malónico de Fórmula (I): em que R~ a~ e R~ b~ devem ser o mesmo e são selecionados do grupo constituído por alquila C~ 1~-C~ 6~; compreende a separação de fases de uma ou mais impurezas do referido éster de carbazol pelo menos uma vez, e que o solvente usado para realizar a referida separação de fases é o ácido acético. Em uma modalidade preferida, o referido ácido acético é ácido acético glacial o qual é mantido a uma temperatura desde cerca de 30°C até cerca de 110°C e o referido éster de carbazol é obtido numa pureza de pelo menos 99,90% em peso, de maneira que a quantidade de impurezas nele presente é de 0,10% ou menos em peso. Em uma modalidade mais preferida do referido processo, a referida temperatura é desde cerca de 50°C até cerca de 70°C e a referida separação de fases é realizada apenas uma vez.
