Mizuno, N Suh, DJ Han, W Kudo, T 2024-01-21T19:07:22Z 2024-01-21T19:07:22Z 2022-01-11 1996-12-23 1381-1169 https://pubs.kist.re.kr/handle/201004/144196 Keggin-type 12-molybdophosphates have been found to catalyze the selective oxidation of isobutane, propane, and ethane into methacrylic acid, acrylic acid, and ethene, respectively, with molecular oxygen. Cs+-, Fe3+-, or Ni2+-substitution for H+ and V5+-substitution for Mo6+ in H3PMo12O40 enhanced the catalytic activity for the oxidation of propane. Among the catalysts tested Cs2.5Fe0.08H1.26PVMo11O40 gave the highest yield of acrylic acid: 13%. It was suggested by IR, XRD, TG-DTA data that the Keggin structure was maintained during the oxidation.
