METHACRYLIC ACID RECOVERY

In the recovery and purification of methacrylic acid produced by the vapor phase catalytic oxydehydrogenation of isobutyric acid the problem of downstream plugging is avoided by the inclusion of a small amount of surfactant in the gaseous effluent at or near the point of its condensation.
