Abstract: The calculation of the above balance shows that the division of stream (5) into the streams (5a) and (5b) used here leads to the fact that in the neutralization stage no excess sodium formate is produced, so that any ejection can be omitted. Furthermore, the water content of the stream (14) comprising sodium formate recirculated to the first crystallization stage in this case can be set to a very low value.

Abstract: The invention relates to a method for producing a solid sodium diformate preparation having a minimum formic acid concentration of 35 percent by weight relative to the total weight of the sodium diformate preparation. According to said method, an aqueous solution having a molar ratio HCOOH: HCOONa of more than 1.5:1 and a molar ratio HCOOH: H2O of at least 1.1:1 is produced from sodium formate and at least 74 percent by weight of formic acid at an elevated temperature, the aqueous solution is crystallized, and the solid phase is separated from the mother liquor. (i) A partial amount (A) of the mother liquor is used during the production of the aqueous solution while (ii) a partial amount (B) of the mother liquor is mixed with a sodium-containing base and the obtained sodium formate-containing mixture is also used during the production of the aqueous solution, optionally after separating a portion of the same and optionally after concentrating the same, the partial amounts (A) and (B) of the mother liquor amounting to 100 percent by weight.
