FIELD: chemistry.
SUBSTANCE: method of producing saturated carboxylic acids of general formula
includes hydrogenation of unsaturated carboxylic acids with hydrazine hydrate in the presence of a nickel catalyst while heating in aqueous sodium hydroxide solution for 3-4 hours. The unsaturated carboxylic acids to be hydrogenated are selected from: methacrylic acid, norbornene carboxylic acid and trans-cinnamic acid; the catalyst used is nickel nanoparticles obtained by reducing nickel (II) chloride hexahydrate with hydrazine hydrate in an aqueous alkaline medium in situ, and the process is carried out in molar ratio NaOH: unsaturated carboxylic acid of 1.3-1.5:1 at 60°C.
EFFECT: simple method of producing compounds of the disclosed structural formula.
