Methanol → Methacrolein

Participants

Reaction Steps

Liquid mixture (IV): a liquid mixture containing liquid methacrolein and liquid methanol, which, in the method of the present invention, is obtained by separation from a reaction mixture (containing methyl methacrylate, water, methacrolein and methanol) produced by the above-mentioned oxidative esterification reaction (the direct ML-to-MMA synthesis reaction). This liquid mixture (IV) can be recycled and introduced into the dehydration tower at an upper portion thereof as the above-mentioned liquid mixture (I) and/or into the absorption tower at an upper portion thereof as the above-mentioned liquid mixture (II).
