H2SO4), which is removed in a cracking step. In the first step, methacrolein is produced in the same way as in the direct oxidation process by gas phase catalytic oxidation, is simultaneously oxidized and is esterified in liquid methanol to get MMA directly.[6]. After esterification and dehydration MMA is obtained. In a second set of reactions, MeP is condensed with formaldehyde in a single heterogeneous reaction step to form MMA:[9]. Ethylene is first hydroformylated to give propanal, which is then condensed with formaldehyde to produce methacrolein, The condensation is catalyzed by a secondary amine. methyl methacrylate; methyl 2-methylprop-2-enoate; methyl 2-methylpropenoate CAD - Chemical Agents Directive, Art.
