Versuchsvorschrift

400 ml of methanol is slowly added with stirring to a mixture of 3 mols of 2,2-bis-(3-allyl-4-hydroxyphenyl)-propane (A1) and potassium hydroxide pellets. The mixture is afterwards carefully heated to 110° C. with the distilling off of 116 ml of methanol. The reaction solution is subsequently held, with reflux cooling, for a further 6 hours at 110° C. The reaction solution is then cooled, neutralised with conc. HCl, and extracted with methylene chloride. The extract is dried, and completely evaporated to dryness to thus yield essentially pure 2,2-bis-[3-(1-propenyl)-4-hydroxyphenyl]-propane (A2), which at room temperature is a very highly viscous yellow liquid. The structural formula A2 is confirmed by microanalysis and H-NMR, MS and UV spectroscopy, as well as by means of gel-permeation chromatography.
