The result shows that for catalyst CT-4A acrolein is a middle product and acrylonitrile, acetonitrile, carbon dioxide and carbon monoxide could be treated as parallel products.
The poor acrolein selectivity of this catalyst was improved by continuous use in the catalytic oxidation for making the particle size of the dispersed bismuth molybdate larger.
我们还发现，在催化氧化环境中连续使用的钼酸铋粒径会越来越长，对丙烯醛的选择性会相应提高。

However, due to the chemical stability of propane and the activity of acrolein, this reaction required a multiple functional catalyst and no great progress was made in this field.
