Abstract
"PROCESSO PARA A PREPARAçãO DE UM áCIDO DICARBOXìLICO". é descrito um processo para a preparação de um ácido dicarboxílico de fórmula (I) H-OOC-(n-C~ 4~H~ x~)-COO-H, na qual x representa 6 ou 8, a partir de ácido acrílico. O citado processo é caracterizado pelo fato de que a) um diéster de ácido dicarboxílico de fórmula (II) R^ 1^-OOC-(n-c~ 4~H~ x~)-COO-R^ 2^ na qual x representa 6 ou 8 e R^ 1^, R^ 2^ independentemente representam C~ 1~-, C~ 2~-, C~ 3~-, C~ 4~-alquila, arila, heteroarila e podem ser idênticos ou diferentes, é reagido com ácido acrílico de modo a obter um ácido dicarboxílico de fórmula (I) e uma mistura de ésteres de ácido acrílico de fórmulas C~ 2~H~ 3~-COOR^ 1^ e C~ 2~H~ 3~-COOR^ 2^, nas quais R^ 1^ e R^ 2^ possuem os significados mencionados acima; b) o ácido dicarboxílico de fórmula(I) obtido na etapa (a) é separado da mistura reacional obtida na etapa (a); C) O C~ 2~H~ 3~-COOR^ 1^, C~ 2~H~ 3~-COOR^ 2^, ou as misturas dos mesmos obtidos na etapa (a) são dimerizados de maneira a obter um diéster de ácido n-buteno-dicarboxílico; e d) o diéster de ácido dicarboxílico obtido na etapa (c) é clivado para o correspondente ácido dicarboxílico de fórmula (I).
