FIELD: chemistry.SUBSTANCE: claimed invention relates to a method of obtaining a (meth)akrylate monomer. Described is the method of obtaining the (meth)akrylate monomer of the general formula (I):in which Rstands for hydrogen or a methyl group, X stands for oxygen, Rstands for a residue of an alkyl group with 3-6 carbon atoms and one aldehyde group, characterised by the fact that an initial product of formula (III):in which Rstands for hydrogen or a methyl group, X stands for oxygen and Rstands for an unsaturated alkyl residue with, at least, one double bond and 3-6 carbon atoms, is subjected to interaction with a carbon monoxide and hydrogen in the presence of a catalyst, which represents a complex, containing rhodium, iridium, palladium and/or cobalt and a phosphorus-containing compound as a ligand, with a ratio of a metal to the ligand preferably constituting from 1:1 to 1:1000, especially preferably from 1:2 to 1:200.EFFECT: obtaining the (meth)akrylate monomer by the method, characterised by the higher efficiency, high selectivity, inconsiderable content of byproducts.8 cl, 1 tbl, 24 ex |
