Abstract

"PURIFICAçãO DE CORRENTE DE SUBPRODUTO NA PREPARAçãO DE POLI (TEREFTALATO DE TRIMETILENO)" A presente invenção refere-se a um processo para preparar poli (tereftalato de trimetileno) a partir de 1, 3-propano diol e tereftalato de dimetila, em que uma corrente de subproduto contendo carbonila é purificada por tratamento com um catalisador ácido. O processo de preparação de poli (tereftalato de trimetileno) envolve reagir 1,3-propanodiol e tereftalato de dimetila sob condições de reação de transesterificação e destilar e condensar as correntes de subproduto metanol e 1,3-propanodiol contendo compostos de carbonila tal como acroleína. A corrente de subproduto condensada é tratada com um catalisador ácido como um resina de troca iónica ácida para reduzir o teor de carbonila da corrente.
