Versuchsvorschrift

33 parts of eugenol, 50 parts of dimethyl carbonate and 2 parts of tri-n-butylphosphine are kept for 15 hours at 190° C. Working up takes place as described in Example 24. 31 parts (88% of theory, based on converted eugenol) of eugenol methyl ether of boiling point 69°-70° C./0.13 mbar are obtained. The conversion is virtually quantitative.
