Abstract

Efficient one-step oxidation of isobutylene to methacrylic acid was achieved over a Mo-V-Te-Cs catalyst. Mo-O-V as "asymmetric lattice oxygen" brings high activity. Te and Cs provide a suitable medium acidity to enhance the selectivity. A record single-step yield of 65% for methacrylic acid was obtained from isobutylene oxidation.
