FIELD: chemistry.
SUBSTANCE: invention relates to the organic synthesis and concerns an advanced method of obtaining ethers bis-α, β-unsaturated dicarboxylic acid, that consists in that the diakylmaleates are subjected to interactions with cyclic olefins in the presence of the catalyst of metathesis with the temperature from 20°C to 90°C.
EFFECT: it makes it possible to obtain ethers of bis-α, β-unsaturated dicarboxylic acids without the use of acrylates, which are easily polymerised during storage as well as to remove a solvent from the process.
