A process can be used for preparing methyl methacrylate (MMA), by direct oxidative esterification of methacrolein. The MMA and polymers produced therefrom feature a very low yellowness index. A workup of the reactor output from the oxidative esterification of methacrolein allows for particularly discolouring by-products to be removed or degraded without significant MMA losses.
