抄録

Vapor-phase catalytic dehydration of 1,2-propanediol was investigated over several solid acid catalysts, such as alumina, silica–alumina, HY zeolite, and β-zeolite. These acids catalyzed the dehydration of 1,2-propanediol to produce propanal (Figure 1Figure 1. Dehydration of 1,2-propanediol to propanal.), while zeolites were particularly deactivated because of deposition of carbonaceous species. An amorphous silica–alumina was modified with metals such as Ag and Cu to stabilize the catalytic activity under hydrogen flow conditions. Ag-modified silica–alumina is a promising catalyst for the production of propanal from 1,2-propanediol.
