Procédé de préparation de dérivés méthacryliques. Ce procédé consiste à soumettre à une oxydation ou ammoxydation un composé comportant un groupement butyle tertiaire, par passage du mélange réactionnel sur un catalyseur ayant pour formule : The present invention relates to a process for the conversion of tertiary-butyl-containing compounds to methacrylic derivatives, and more particularly to a process for the conversion of tertiary-butyl-containing compounds selected from the group consisting of alkyl tertiary-butyl ethers, tertiary-butyl alcohol, isobutylene dimer (2,2,4-trimethylpentene) and isobutylene trimer, to methacrolein, methacrylic acid or methacrylonitrile.
