Thermodynamic Study of One-step Production from Isobutene to Methyl Methacrylate

Methyl methacrylate (MMA) has emerged as an essential industrial monomer. However, the toxic by-production and shortage supply of MMA in global market gained great attention. Herein, a one-step synthesis to produce from isobutene via direct oxidative esterification process been demonstrated curb aforementioned downsides. Thermodynamic analysis Gibbs free energy minimization method proved feasibility this route equilibrium constant. Despite tert-butanol isobutane showed higher constant than isobutene, they should be avoided. Isobutane is highly flammable while precursor exorbitant. Thus, was selected for compositions screening. Isobutene conversion 90% 15% yield at 700 °C IBN: O2: MeOH ratio with 1:7:1. This mainly limited by generation side reactions reaction CH3OH O2. By varying feedstock 1:2:1, increased ~25%.
