The invention relates to a method for producing and using a solid sodium diformate having a high formic acid content, to the use thereof in animal foods in the form of an acidifier, preservatives, ensilage auxiliary agents, fertilizers, and a growth and productivity-stimulating agent and the inventive animal food additives containing sodium diformate.

Sodium diformate production and use

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 sodium diformate preparation, in which, at elevated temperature, an aqueous solution (E) is produced which comprises sodium formate and formic acid in a molar ratio of HCOOH:HCOONa of greater than 1.5:1 and which has a molar ratio of HCOOH:HO of at least 1.1:1, the aqueous solution (E) is brought to crystallization to obtain a solid phase (F) and a mother liquor (G), and the solid phase (F) is separated off from the mother liquor (G),
