Versuchsvorschrift

p-Cyclohexylphenol (83.1 g) (0.5 mol) was dissolved in 300 ml of toluene. Subsequently, 150 g of 2-chloroethyl vinyl ether, 25 g of sodium hydroxide, 5 g of tetrabutylammonium bromide, and 60 g of triethylamine were added to the above solution and the solution was allowed to react at 120° C. for 5 hours. The reaction solution was washed with water and the excess amounts of chloroethyl vinyl ether and toluene were distilled off. The obtained oil was purified by distillation under reduced pressure, thereby 4-cyclohexylphenoxyethyl vinyl ether was obtained.
