Abstract: 저온과 대기압에서 높은 수율로 알파-베타 불포화 카르복실산을 제조하는 방법은 분자 산소와 올레핀의 두 단계 촉매 증기상 산화를 포함한다. 제 1 단계에서, 올레핀은 알파-베타 불포화 알데히드를 함유하는 제1 단계 생성물을 생성하기 위해 다음 화학식의 조성을 갖는 촉매 A를 사용하여 산화한다: Mo a Pd b Bi c Fe d X 1   e X 2   f X 3   g O z , 여기서 X 1 =Co, Ni, V, Pt, Rh 중 하나 이상; X 2 =Al, Ga, Ge, Mn, Nb, Zn, Ag, P, Si, W 중 하나 이상; X 3 =K, Mg, Rb, Ca, Sr, Ba, Na 중 하나 이상; O는 산소. 제2단계에서, 제1 단계 생성물의 알파-베타 불포화알데히드는 아래 화학식의 조성을 갖는 촉매 B를 사용하여 주로 알파-베타 불포화 카르복실산을 생성하기 위해 산화된다: Mo a V b Al c X d Y e O z , 여기서, X=W 또는 Mn 또는 둘다; Y=Pd, Sb, Ca, P, Ga, Ge, Si, Mg, Nb, K 중 적어도 하나 이상; O는 다른 원소들의 원자가를 만족시키는 산소. 산소의 일부는 제1 단계와 제2 단계 사이 또는 다단계에서 반응 스트림에 도입된다. 특히 본 발명은 아크릴산 또는 메타아크릴산을 수득하기 위해 프로필렌 또는 이소부틸렌의 두 단계 촉매 산화방법에 관한 것이다.
