Sb-Re composite oxide catalyst for lower alkane selective oxidation reaction

摘要

PROBLEM TO BE SOLVED: To provide a catalyst for selective oxidation reaction, which is composed of a new Sb-Re complex oxide and capable of catalyzing the selective oxidation to an alkene such as isobutylene and/or an oxygen containing compound such as methacrolein in the presence of an excess amount of oxygen and to provide a method for producing the alkene such as isobutylene and/or the oxygen containing compound such as methacrolein from isobutane or the like using the catalyst for the selective oxidation reaction, which is composed of the Sb-Re complex oxide. ;SOLUTION: An alkene such as isobutylene or an oxygen containing compound such as methacrolein corresponding to a lower alkane is produced by subjecting the lower alkane such as isobutane to vapor phase catalytic oxidation at 400 to 600°C in the presence of gaseous molecular oxygen of 30 to 60 kPa by using a Sb-Re complex oxide catalyst such as SbRe2O6 or Sb4Re2O13.;COPYRIGHT: (C)2001,JPO
