2-甲基丙烯醛上游产品

2-甲基丙烯醛下游产品

1.制备异丁烯醛的方法，将异丁烯和叔丁醇中的至少一种，用含分子氧的气体在氧化催化剂组合物Ｍｏ₁₂Bi_aCe_bK_cFe_dA_eB_fO_g存在下进行气相催化氧化，Ａ是指单独的钴，或者镁与钴的原子比不大于０．７的钴和镁的混合物，Ｂ是指铷、铯或其混合物，并且a、b、c、d、e、f和g分别是相应于钼的１２个原子的铋、铈、钾、铁、Ａ、Ｂ和氧的原子比。通过本发明的方法，采用一种氧化催化剂组合物，可以稳定地生产高产量的异丁烯醛，这种氧化催化剂组合物具有比较简单的结合组成，并因此可以简单地制备，而且它不仅具有由于优良的热稳定性和抗还原性而延长了的催化剂寿命，而且具有对异丁烯醛优良的选择性，其中这种催化剂组合物以特定量和特定相对比例含有铋、铈、铁和钾，而不包括那些产生环境污染和毒害问题的成分，制备原料也不必采用在水中溶解度低的化合物，如钨、锑和铌化合物，它们通常用于获得所需的催化性能，但是其使用由于难以获得均相催化剂组合物而是不利的。
