Abstract
PROCESSO PARA A PRODUÇÃO E PURIFICAÇÃO DE FASES AQUOSAS. A presente invenção refere-se a um processo para a purificação de uma fase não purificada contendo um produto-alvo, preferivelmente ácido (met)acrílico, água e pelo uma impureza diferente do produto-alvo e da água, para uma fase purificada, apresentando um estágio de processo, o qual contém as seguintes etapas do processo: a) o produto-alvo e a água são separados por cristalização da fase não purificada formando uma suspensão, contendo uma lixívia-mãe e cristais, sendo que essa separação por cristalização é efetuada a uma temperatura T1 na faixa de Te 15ºC (menor ou igual) T1 (menor ou igual) Te + 3ºC (Te = temperatura eutéctica da fase não purificada); b) os cristais são separados pelo menos parcialmente da lixívia-mãe; c) pelo menos uma parte dos cristais separados é fundida para uma massa em fusão, sendo que essa fusão é efetuada a uma temperatura T2 na faixa de T1 < T2 (menor ou igual) T2 + 20ºC; e d) pelo menos uma parte da massa em fusão é reconduzida à etapa b), sendo que a parte da massa em fusão não reconduzida está presente como uma fase purificada. A invenção refere-se também a um processo para a produção de uma fase purificada contendo um produto-alvo e água, uma fase purificada contendo um produto-alvo e água, um processo para a produção de um polímero à base de ácido (met)acrílico, polímeros, obteníveis por esse processo, produtos químicos, tais como, por exemplo, fibras ou artigos conformados, bem como o uso de polímeros.
