| abstract | The present invention relates to the dehydration of gases obtained by catalytic oxidation and containing methacrolein. According to the invention, a gaseous effluent is treated, containing methacrolein and obtained by catalytic oxidation of isobutylene or tertiary butyl alcohol, and the water is removed therefrom by sudden cooling in an aqueous liquid, in several cooling stages. , under gradually increasing pressure. Methacrolein is a synthetic intermediate; by oxidation, it gives methacrylic acid making it possible to obtain various polymers. |
