Here is a basic question that has been bugging me for a while.
Alcohols can be dehydrated with an acid catalyst like phosphoric acid or KHSO4. What if 1,2-propanediol was treated this way? Would the product be
acetone, allyl alcohol or propionaldehyde? Glycerine can yield acrolein

I had this note to myself saved:
Surupa Dimple Abraham, MS Thesis University of Missouri-Columbia
Reactive distillation of propylene glycol can give ~25% 1-propanol
Gas phase tube furnace reactions can give ~50% propionaldehyde
Catalysts are basic alumina and magnesia with sodium compounds

Thanks!!! Just what I was looking for.
He briefly mentions acid catalysts with the product being 65% propionaldehyde. Could be easily oxidized to propionic acid.
