Abstract

"PROCESSO PARA A OBTENçãO DE áCIDO FóRMICO ANIDRO OU SUBSTANCIALMENTE ANIDRO, USO DE UMA CARBOXAMIDA, E, APARELHO PARA REALIZAR UM PROCESSO". A invenção diz respeito a um método para a produção de ácido fórmico anidro ou substancialmente anidro. O método é caracterizado em que um líquido da fórmula geral (I) que é usado como agente de extração também é usado como líquido de lavagem para o gás de saída produzido durante a implementação do método, em que os radicais R^ 1^ e R^ 2^ representam grupos alquila, cicloalquila, arila ou aralquila ou R^ 1^ e R^ 2^ juntos formam com o átomo N um anel heterocíclico de cinco ou seis membros e em que apenas um dos radicais é um grupo arila e em que R^ 3^ significa hidrogênio ou um grupo alquila C~ 1~-C~ 4~
