To a clean, dry stirred tank pressure vessel with nitrogen inlet is charged 1434.05 g (9.95 moles) of 2-Naphthol and 1445 mLs of Toluene. The vessel is purged with nitrogen and a catalytic amount (4.97 g) of BF3/Etherate Solution is charged. The temperature is raised to 110° C. and 2310.86 g (39.79 moles) of Propylene Oxide is added at a constant rate to keep the pressure inside the vessel below 50 psig. After all Propylene Oxide is added, the reaction mixture is allowed to react for an additional 3 hours after which the temperature is raised to 150° C. and the toluene is distilled off under nitrogen sparge. After the distillation of Toluene, the temperature is cooled to 110° C. and vacuum is applied for 1 hour.
