실험 절차

To a clean, dry stirred tank pressure vessel with nitrogen inlet is charged 952.71 g (6.61 moles) of 2-Naphthol and 1445 mLs of Toluene. The vessel is purged with nitrogen and a catalytic amount (4.96 g) of BF3/Etherate Solution is charged. The temperature is raised to 110° C. and a mixture of 1919.03 g (33.04 moles) of Propylene Oxide and 873.28 g (19.82 moles) of Ethylene Oxide is added at a constant rate to keep the pressure inside the vessel below 50 psig. After all Propylene Oxide/Ethylene 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.
