    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.
