FIELD: chemistry.SUBSTANCE: invention relates to improved method of obtaining ethers of (met)acrylic acid, including re-etherification of low-boiling ether of (met)acrylic acid, boiling temperature of which is lower than boiling temperature of ester, formed as a results of re-etherification, with initial alcohol in presence of main ion-exchanging substance as catalyst, and inhibitor of polymerisation, with re-etherification being carried out at temperature within the range from 50°C to 140°C. Obtained product contains insignificant amounts of byproducts and catalyst residues.EFFECT: method is realised without labour-consuming separation of catalyst.20 cl, 8 ex |
