Abstract

"PROCESSO DE FABRICAçãO DE ACETATO DE CELULOSE". A invenção fornece um processo para fabricar acetato de celulose a baixo custo, o qual é útil como um plástico biodegradável, usando farinha de milho de espiga de milho que tem sido desperdiçada até o momento como um material bruto. Mais especificamente, a invenção fornece um processo para fabricar acetato de celulose, que compreende as etapas de: vaporização da farinha de milho de espiga de milho a uma temperatura de 150 a 250<198>C e uma pressão de 20 a 29 MPa; filtração da farinha de milho de espiga de milho vaporizada para obter um produto sólido; e desidratação e acetilação pela adição de anidrido acético e ácido sulfúrico ao produto sólido. A vaporização é realizada pelo uso de um vaso de pressão e a filtração é realizada pelo uso de um dispositivo de filtração.
