FIELD: chemistry.
SUBSTANCE: invention relates to a method for synthesis of at least one compound of formula (I) or one of its salts, in which R is a group of COOH, CH2OH or CHO, where but-3-ene-1,2-diol (BDO) is subjected to oxidation in the presence of a catalyst containing an active phase based on at least one noble metal selected from palladium, gold, silver, platinum, rhodium, osmium, ruthenium and iridium, and a substrate containing alkaline sites and selected from hydrotalcites (HT), brucites, hydroxyapatite Ca10(PO4)6(OH)2, tricalcium phosphate Ca3(PO4)2, calcium hydrophosphate CaHPO4(0–2) H2O, calcium diphosphate Ca2P2O7, octaculphosphate Ca8H2(PO4)6.5H2O, tetrapotassium phosphate Ca4(PO4)2O, amorphous calcium phosphates Ca3(PO4)2.nH2O, oxides, hydroxides, carbonates, bicarbonates, phosphates, diphosphates and hydrophosphates of calcium, cesium, lithium, rubidium, potassium, magnesium, barium, cerium, lanthanum, aluminum, zinc, copper and their mixtures.
Formula (I).
EFFECT: invention also relates to use of said reaction for producing bio-accessible methionine compounds used, in particular, for feeding animals.
