Abstract: Acrylates and methacrylates were obtained by oxidative esterufucation of propylene or isobutylene (I) in the presence of O and C2H4 or an alc., in a single fluidized bed reactor contg. oxidn. catalysts at 200-600≦̸C. A reactor was charged with 80% 50:50 mixt. of Ni2.5Co4.5Fe3BiPO.5/0.5Mo12Ox and SiO2 and 20% 62:38 mixt. of V3W1.2Mo12Ox and SiO2.Air-I-MeOH(10:1:2) was fed to the reactor at 355oC and 1 atm. and after contact time 5 s the product yield was methyl methacrylate 30.0, I 53.0, acrolein 1.0, and methacrolein 2.0 mol. percent with a trace of methacrylic acid.

Abstract: The production of acrylates and methacrylates, made by the oxidative esterification of propylene or isobutylene wherein gaseous reactants are contacted with one or more catalysts and ethylene or an alcohol can be advantageously conducted in a single fluid bed reactor to obtain the desired ester.
