PRODUCTION OF ACIDIC PROPIONATES Russian patent published in 2012 - IPC C07C51/41 A23K1/16 A23K1/175 C07C53/122 

FIELD: chemistry.

SUBSTANCE: invention relates to a solid composition having antifungal action and containing at least one compound which contains propionic acid, selected from a group comprising compounds of formula (I): (Mⁿ⁺)(H⁺)_x(CH₃CH₂C(O)O^-)_(n+x) (I), in which Mⁿ⁺ denotes sodium, wherein n denotes 1, and x denotes a number from 1.8 to 2.2, [NaH₂(CH₃CH₂C(O)O)₃] and [NaH_1.3(CH₃CH₂C(O)O)_2.3], wherein content of said at least one compound containing propionic acid is at least 96 wt % per total weight of the composition; and a method of preparing a solid composition containing at least one compound of formula (I) containing propionic acid, in which Mⁿ⁺ denotes sodium, wherein n denotes 1 and x denotes a number from 0.25 to 5, according to which, from neutral sodium propionate and propionic acid in molar ratio from 1:0.25 to 1:5, while heating, a homogeneous mixture is obtained or at least partial solidification of this mixture is caused, wherein moisture content of the homogeneous mixture is less than 1 wt % per total weight of the mixture or crystallisation of said mixture is caused, wherein moisture content of the homogeneous mixture varies from 1 to 15 wt % per total weight of the mixture.

EFFECT: invention relates to use of the composition as a silo preservative, a preservative, an acidifier, a food additive, feed material or animal feed material additive.
