To phenol (35.3 g, 0.37 moles) was added 10.6 g of zirconium n-propoxide in n-propanol consisting of 21.6% zirconium (0.025 mole) and 10.8% free n-propanol. The mixture was distilled at atmospheric pressure removing n-propanol. Ethyl disulfide (30.6 g, 0.25 moles) was added, and the mixture was heated under nitrogen while ethyl mercaptan was removed continuously by distillation. Heating was continued for a total of 6.5 hours during which temperature slowly increased to 200° C. Distillation of the mixture at 0.5 mm mercury to a maximum head temperature of 84° C. yielded 31.7 g of distillate. GC analysis indicated the distillate contained 12.4 g of phenol (35% recovered) and 15.9 g of ortho-(ethylthio)phenol (41% yield).
