    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: Propionic acid-containing composition (A) in solid and preferably pure form, comprises at least a metal compound (I). Propionic acid-containing composition (A) in solid and preferably pure form, comprises at least a metal compound (I) of formula ((M(n+))(H +>) x(CH 3CH 2C(O)O ->) (n+x)). M(n+) : n-valent alkalimetal- or alkaline earth metal cation; n : 1 or 2; and x : 0.25-5. Provided that when M(n+) is potassium, then x is not equal to 0.75-1.75. An independent claim is also included for the preparations of (A) comprising: either heating a neutral alkalimetal- and/or alkaline earth metal propionate and propionic acid in a molar ratio of 1:0.25 to 1:5 to give a homogeneous mixture and partially solidifying the homogeneous mixture, where the homogeneous mixture contains less than 1 wt.% of water; or heating a neutral alkalimetal- and/or alkaline earth metal propionate and propionic acid in a molar ratio of 1:0.25 to 1:5 to give a homogeneous mixture and crystallizing the homogeneous mixture, where the homogeneous mixture contains 1-15 wt.% of water and the molar ratio of the neutral alkali metal- and/or alkaline earth metal propionate to propionic acid is 1:0.75 to 1:1.75 if M(n+) is potassium.

    Abstract: 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:H2O 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), (i) the mother liquor (G) being fed to a distillation apparatus (DV); (ii) the mother liquor (G) in the distillation apparatus (DV) being admixed with a so- dium-comprising base (A) to obtain a mixture (B) comprising sodium formate and formic acid; (iii) admixing the mixture (B) obtained from step (ii) with formic acid (D) to obtain the aqueous solution (E); and (iv) excess water (C) essentially being ejected only by withdrawal from the distillation apparatus (DV); and also to the use of a solid sodium diformate preparation obtainable by the inventive process as feed additive for animal feed, in particular for monogastric animal feed and especially for animal feed for hogs and/or poultry.

    Abstract: Preparation of a solid sodium formate preparation comprises (i) preparing an aqueous solution, which exhibits formic acid, sodium formate and water; (ii) subjecting the aqueous solution to crystallization and separating a solid phase from mother liquor; (iii) supplying the mother liquor during the production of the aqueous solution, to a distilling device; (iv) mixing the mother liquor with a sodium-containing base to form a mixture containing sodium formate and formic acid; (v) mixing the mixture with formic acid; and (vi) removing the water by withdrawing from the distilling device. Preparation of a solid sodium formate preparation with a content of at least 35 wt.% of formic acid, comprises: (i) at increased temperature, preparing an aqueous solution, which exhibits a molar ratio of formic acid and sodium formate of more than 1.5:1 and a molar ratio of formic acid and water of at least 1.1:1; (ii) subjecting the aqueous solution to crystallization and separating a solid phase from mother liquor; (iii) supplying the mother liquor, optionally after removal of a partial quantity of the mother liquor, during the production of the aqueous solution, to a distilling device; (iv) mixing the mother liquor with a sodium-containing base to form a mixture containing sodium formate and formic acid; (v) mixing the mixture with formic acid under receipt of the aqueous solution; and (vi) removing the water that is not needed for the production of the aqueous solution, by withdrawing from the distilling device.
