Abstract

processo para obter ácido fórmico. a invenção refere-se a um método para obter ácido fórmico pela separação térmica de um fluxo contendo ácido fórmico e uma amina terciária (i), em que um fluxo líquido que contém ácido fórmico e uma amina terciária (i) em uma proporção molar de 0,5 a 5 é produzido pela combinação de amina terciária (i) e uma fonte de ácido fórmico, 10% a 100% em peso dos componentes secundários contidos em dito fluxo são separados, e ácido fórmico é removido por destilação do fluxo de líquido resultante em um dispositivo de destilação em uma temperatura de fundo de 100ºc a 300º c e uma pressão de 30 hpa abs a 3.000 hpa abs, em que o produto de fundo do dispositivo de destilação é separado em duas fases líquidas e a fase líquida superior é retornada para a fonte de ácido fórmico e a fase líquida inferior é retornada para separação dos componentes secundários e/ou para o dispositivo de destilação.process to obtain formic acid. The invention relates to a method for obtaining formic acid by thermally separating a flux containing formic acid and a tertiary amine (i), wherein a liquid stream containing formic acid and a tertiary amine (i) in a molar ratio of 0.5 to 5 is produced by the combination of tertiary amine (i) and a formic acid source, 10% to 100% by weight of the secondary components contained in said stream are separated, and formic acid is distilled off from the liquid stream. resulting in a distillation device at a background temperature of 100 ° C to 300 ° C and a pressure of 30 hpa abs to 3,000 hpa abs, wherein the background product of the distillation device is separated into two liquid phases and the upper liquid phase is returned. for the formic acid source and the lower liquid phase is returned for separation of the secondary components and / or for the distillation device.
