| titleOfInvention | A PROCEDURE FOR THE CONTINUOUS MANUFACTURE OF METHACRYLIC ACID. |
| abstract | A process for the continuous manufacture of methacrylic acid from the reaction mixture obtained in the oxidation of isobutylene with dinitrogen tetraoxide in the presence of nitric acid and containing α -hydroxyisobutyric acid and its derivatives, characterized in that it is extracted from The reaction mixture is free nitric acid and the residue is heated, dissolved in acetic acid, in a polar organic reaction medium, heated to temperatures of at least 160º C and whose boiling point is higher than 160º C, continuously being extracted from the medium. reaction methacrylic acid formed.
