Versuchsvorschrift

Subsequently, 50 ml of acetonitrile, 0.092 mol of β-phenoxyethyl-p-tosylate, and 0.1 mol of p-ethylphenol were placed in a flask equipped with a stirrer. A 48 wt% aqueous solution of caustic soda (0.12 mol equivalent) was added dropwise at an inner temperature of not more than 75° C. while stirring. The mixture was stirred while refluxing for 2 hours. The reaction mixture was allowed to cool. On pouring the reaction mixture at about 40° C. into a methanol-water mixture, crystals precipitated. These crystals were separated by filtration, and then dried to yield 1-phenoxy-2-p-ethylphenoxyethane (m.p., 107°-108° C.). The yield was 98%.
