Where can I find allyl alcohol?

Other methods. In principle, allyl alcohol can be obtained by dehydrogenation of propanol. In the laboratory, it has been prepared by the reaction of glycerol with oxalic or formic acids. Allyl alcohols in general can be prepared by allylic oxidation of allyl compounds by selenium dioxide.

What is the structure of allyl alcohol?

What is vinyl and allyl alcohol?

Both allyl and vinyl groups have slightly similar structures with a small variation. … The key difference between these two structural components is the number of carbon and hydrogen atoms. Allyl groups have three carbon atoms and five hydrogen atoms whereas vinyl groups have two carbon atoms and three hydrogen atoms.
