titleOfInvention | Process for preparation of methyl methacrylate by esterification during oxidation |
abstract | The invention relates to a process for preparation of methacrylic acid, comprising the steps: a) providing a feed composition comprising a main compound selected from isobutylene and tert-butyl alcohol and at least one co-compound selected from the group consisting of methanol, dimethyl ether and formaldehyde; b) subjecting the feed composition provided in step a) with at least a first part of said at least one co-compound to a catalytic reaction zone and obtaining an oxidation phase comprising methyl methacrylate and methacrylic acid. The invention also relates a process for preparation of methyl methacrylate, further comprising the step of: c) esterification of at least a part of the oxidation phase obtained in step b), to an apparatus for preparation of methacrylic acid, to an apparatus for preparation of methyl methacrylate, to a process carried out in the apparatus, to methacrylic acid, to methyl methacrylate, to methacrylate esters, to a process for preparation of a polymer comprising at least one methacrylic acid, methyl methacrylate and/or methacrylate ester monomer unit, to a polymer comprising at least one methacrylic acid, methyl methacrylate and/or methacrylate ester monomer, to a process for preparation of a composition, to a composition, to chemical products, and to the use of at least one of methacrylic acid, methyl methacrylate, methacrylate ester, a polymer and/or a composition in chemical products. |
