METHOD OF REGULATING THE WATER CONTENT IN A CONTINUOUS METHOD FOR PRODUCING METHACROLEIN

摘要

The invention concerns the regulating of the water content in a method for producing methacrolein. Methacrolein is used in chemical synthesis, in particular as an intermediate product for producing methacrylic acid, methylmethacrylate or also active substances, odorous substances or flavourings. The present invention concerns in particular the regulating of the water content in a method for producing methacrolein from formaldehyde and propionaldehyde by means of Mannich condensation.
