摘要：
PROCESS FOR THE PRODUCTION OF A PREPARATION FOR A SOLID SODIUM DIFORMATE, AND USE OF A PREPARATION FOR A SOLID SODIUM DIFORMIATE. The present invention relates to a process for producing a solid sodium diformate preparation having a formic acid content of at least 35% by weight based on the total weight of the sodium diformate preparation, wherein at elevated temperature , an aqueous solution (E) is produced comprising sodium formate and formic acid in a molar ratio of HCOOH: HCOONa greater than 1.5: 1 and having a molar ratio of HCOOH: H ~ 2 ~ O of At least 1.1: 1, the aqueous solution (E) is crystallized to obtain a solid phase (F) and a mother liquor (G) and the solid phase (F) is separated from the mother liquor (G), ( (i) the mother liquor (G) being fed to a distillation apparatus (DV)； (ii) the mother liquor (G) in the distillation apparatus (DV) being mixed with a base comprising sodium (A) to obtain a mixture (B) comprising sodium formate and formic acid； (iii) mixing the mixture (B) obtained from step (ii) with formic acid (D) to obtain an aqueous solution (E) and (iv) excess water (C) being essentially ejected only by removing the distillation apparatus (DV) and also the use of a solid sodium diformate preparation obtainable by the inventive process as a feed additive for animal feed, in particular for monogastric animal feed and especially for pig and animal feed. / or poultry.PROCESSO PARA A PRODUÇçO DE UMA PREPARAÇçO DE DIFORMIATO DE SàDIO SàLIDA, E, USO DE UMA PREPARAÇçO DE DIFORMIATO DE SàDIO SàLIDA. A presente invenção diz respeito a um processo para a produção de uma preparação de diformiato de sódio sólida tendo um teor de ácido fórmico de pelo menos 35 % em peso com base no peso total de preparação de diformiato de sódio, em que, em temperatura elevada, uma solução aquosa (E) é produzida, que compreende, formiato de sódio e ácido fórmico em uma razão molar de HCOOH:HCOONa maior do que 1,5:1 e que tem uma razão molar de HCOOH:H~ 2~O de pelo menos 1
