Versuchsvorschrift

A 100 g quantity of 4-hydroxybenzophenone was added to 500 ml of water containing 22.0 g of sodium hydroxide. The solution was stirred until all of the benzophenone had dissolved. After the solution had cooled to 5°-10° C., there was added 45.5 g of acrylyl chloride over a period of 30 minutes, to yield a white solid which was recovered by filtration after the solution had been stirred for 2 hours at 5°-10° C. and an additional hour at room temperature. The white solid was recrystallized from ethanol and found to have m.p. 44°-46° C. Infrared and NMR spectra confirmed the structure of 4-acryloxybenzophenone.
