What is the product of a reaction between oleic acid and P2O5, with pyridine as a solvent?
Accepted Answer
The reaction of oleic acid with P2O5 in the presence of pyridine is a classic dehydration reaction. P2O5 acts as a powerful dehydrating agent, removing water molecules from oleic acid to form an unsaturated cyclic anhydride. The exact product will depend on the reaction conditions, but it is likely to be a mixture of various anhydride isomers. Pyridine acts as a base to facilitate the reaction and neutralize the acidic byproducts.
