Abstract
"PROCESSO PARA A PREPARAçãO DE LACTAMAS CìCLICAS". A invenção diz respeito a um método para produzir lactamas cíclicas da fórmula (II), reagindo-se um composto (I) da fórmula (I) com água na presença de um agente de diluição orgânico, líquido na fase líquida. Na fórmula (II), n e m respectivamente podem ter os valores 0, 1, 2, 3, 4, 5, 6, 7, 8 e 9 e a soma de n + m é pelo menos 3, preferivelmente pelo menos 4, R^ 1^ e R^ 2^ representam grupos alquila C~ 1~-C~ 6~, cicloalquila C~ 5~-C~ 7~ ou arila C~ 6~-C~ 12~. Na fórmula (I), R^ 1^, R^ 2^, m e n são definidos como acima e R representa grupos nitrila, amida do ácido carboxílico e de ácido carboxílico. O método da invenção é ainda caracterizado em que a) o composto (1) é reagido com água na fase líquida, na presença de um agente de diluição orgânico líquido (III) para formar uma mistura (IV) contendo uma lactama (II) e a dita mistura (IV) é submetida a um tratamento aquoso para se obter um sistema de fase dupla.
