Abstract

"PROCESSO PARA A OBTENçãO DE áCIDO FóRMICO ANIDRO OU SUBSTANCIALMENTE ANIDRO, USO DE UM FLUXO DE VAPOR EM UM PROCESSO, E, APARELHO PARA REALIZAR UM PROCESSO". A invenção diz respeito a um método para a obtenção de ácido fórmico que seja completamente isento de água ou isento de água em um grau grande. O ácido fórmico aquoso é produzido primeiro pela hidrólise do formiato de metila e depois liberado da água em reprocessamento subseq ente. O método da invenção é caracterizado em que o vapor d'água que é usado para a hidrólise do formiato de metila e para aquecer uma coluna de destilação usada para o reprocessamento também é usado como vapor de separação para retirar por separação a água residual. A água residual separada é produzida durante o reprocessamento.
