The results of in situ DRIFTS on propylene oxidation show that the allyl species originated from α-H abstraction of propylene were located at the wavenumbers of 1454 cm~(-1) and 1427 cm~(-1). The rate-determining step is the abstraction of an α-H abstraction from a lattice oxygen linked to a bismuth ion to form a π-allyl intermediate coordinated to a molybdenum ion. The metal-oxo group then attacks the allyl intermediate forming a σ-bonded oxygen-allyl species, which is in a rapid equilibrium with the π- bonded species. The σ-bonded species then transforms to acrolein by further abstraction of α-H. Such species as formate, carboxylate, carbonate transform to deep oxidation products. The acetone was derived from propylene by an enolic species at lower temperatures.

丙烯氧化反应体系的原位漫反射红外光谱研究结果表明，由丙烯脱氢生成的烯丙基中间物种吸收峰在1454cm~(-1)和1427cm~(-1)处；基于此提出了较完整的丙烯氧化反应网络：丙烯选择氧化生成丙烯醛主要经历丙烯脱除甲基上的一个H，生成烯丙基物种，该物种嵌氧生成σ-O络合物，脱氢得到丙烯醛前驱体，脱附生成丙烯醛；完全氧化产物是由催化剂表面上生成甲酸盐、羧酸盐、碳酸盐等形式的中间物种转化而成；较低反应温度下丙烯氧化生成丙酮，通过烯醇式中间物种氧化生成丙酮前驱体得到。
