A method for production of methyl methacrylate by oxidative esterification using a heterogeneous catalyst |
| abstract |
The present invention relates to a process for the preparation of methyl methacrylate from methacrolein and methanol; said method comprises contacting in a reactor a mixture comprising methacrolein, methanol and oxygen with a heterogeneous catalytic catalyst bed comprising a support and a noble metal, the oxygen mass transfer rate in hours. -1 divided by the space-time yield in moles of methyl methacrylate / kg.catalyst hour in the catalyst bed being at least 25 kg of catalyst / mole of methyl methacrylate. |
