Versuchsvorschrift

In 300 ml of toluene, 83.1 g (0.5 mol) of p-cyclohexylphenol was dissolved, and then 150 g of 2-chloroethyl vinyl ether, 25 g of sodium hydroxide, 5 g of tetrabutylammonium bromide and 60 g of triethylamine were added thereto, followed by a reaction at 120° C. for 5 hours. The reaction solution was washed with water, and excess chloroethyl vinyl ether and toluene were removed by distillation. The resulting oil was purified by distillation under reduced pressure to obtain 4-cyclohexylphenoxyethyl vinyl ether.
