    摘要： The method disclosed herein relates to two stage catalytic processes for converting syngas to acetic acid, acrylic acid and/or propylene. More specifically, the method described and claimed herein relate to a method of producing acrylic acid and acetic acid comprising the steps of: a) providing a feedstream comprising syngas; b) contacting the feedstream with a first catalyst to produce a first product stream comprising C2-C3 olefins and/or C2-C3 paraffins; and c) contacting the first product stream with oxygen gas and a second catalyst, thereby producing a second product stream comprising acrylic acid and acetic acid, wherein there is no step for separating the components of the first product stream before the first product stream is contacted with the second catalyst.

    摘要： The aliphatic carboxylic acids, e.g., acetic acid, are selectively prepared, even on an industrial scale, by controlledly oxidizing the corresponding alkanes, e.g., ethane, with a source of oxygen, in the presence of a catalytically effective amount of an advantageously supported heteropolyacid catalyst having the formula (I):[A.sub.a B.sub.b ].sub.f [C.sub.c D.sub.d E.sub.e O.sub.x ].sup.f-(I)in which A is at least one monovalent cation selected from among hydrogen, an alkali metal, or the ammonium ion; B is VO.sup.2 +, VO.sup.3 +, an alkaline earth metal ion, or an ion of a metal of Groups VII A, VIII, I B, IV B and V B of the Periodic Table; C is Mo and/or W; D is phosphorus, arsenic, antimony, silicon, germanium and/or boron; E is vanadium, optionally in combination with at least one metal of Groups V A, VII A and VIII of the Periodic Table or chromium; f=a+.alpha.b wherein .alpha. depends on the charge of the ion B, which is equal to 2, 3 or 4; c is a number ranging from 5 to 20-e; d is a number ranging from 1 to 5; and e is a number ranging from 1 to 9.
