主要产物

As mentioned earlier, elastinolysiss thought to be an essential component of emphysema.3 This is supported by both pathophysiologic and biochemical investigations, which show reduced lung elastic recoil, disrupted elastic tissue structure, higher circulating levels of elastin peptide breakdown products, and higher levels of desmosine in urine and lung secretions.3 Of the macrophage-derived MMPs identified in emphysematous and COPD tissue, the gelatinases MMP2 and MMP9 are elastinolytic.

正如早些时候提及的，elastinolysiss被认为是肺气肿的主要成份之一。这可以由病理生理研究与生化研究所证实，这两项研究同时提示肺弹性活力的降低，弹性组织结构的断裂，弹力蛋白肽分解产物循环水平的增高，以及尿与肺脏分泌物中锁链素水平的增高。在气肿型或COPD组织中，经确定的巨噬细胞源性的金属蛋白酶中，elastinoly的MMP2与 MMP9是elastinolytic。

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。
