Abstract: TRI-N-BUTYL VANADATE IS PRODUCED IN SIGNIFICANTLY HIGH YIELDS WHEN VANADIUM PENTOXIDE (V2O5) IS REACTED WITH N-BUTANOL IN THE PRESENCE OF TOLUENE. A STOICHIOMETRIC EXCESS OF N-BUTANOL FURTHER ENHANCES THE IMPROVED YIELDS. YIELDS ARE FURTHER IMPROVED IN A PREFEREED EMBODIMENT WHEN CONDENSED VAPORS OF BUTANOL AND TOLUENE PASS THROUGH A QUANTITY OF VANADIUM PENTOXIDE AND ARE RETURNED TO A REFLUXING QUANTITY OF BUTANOL AND TOLUENE.
