| titleOfInvention | Method for production of acrolein and acrylic acid |
| abstract | In the production of acrolein and acrylic acid by the catalytic gas phase oxidation of propylene with a molecular oxygen-containing gas, a method is provided which enables acrolein and acrylic acid to be stably produced with a high yield for a long time from propylene by effectively repressing such secondary reactions as are responsible for the formation of organic acids, high boiling compounds, and tarry compounds, the deposition of carbonized materials, and the deterioration of the quality of products. The content of unsaturated hydrocarbons (excluding propylene) of 2 to 5 carbon atoms in the raw material for propylene is kept below 500 ppm (by weight). Particularly, it is proper to use a raw material for propylene which has a content of unsaturated hydrocarbons (excluding propylene) of 2 to 5 carbon atoms of not more than 200 ppm (by weight) and a total content of diene and acetylenic compounds of 2 to 5 carbon atoms of not more than 200 ppm (by weight). |
