Versuchsvorschrift

11.0 Parts of resorcinol, 10.0 parts of citronellyl acetate and 0.5 parts of p-toluene sulphonic acid are heated at 115° C. for 45 hours. The reaction mixture is then taken up in ether, washed with sodium bicarbonate solution, water, and evaporated. The residual oil is distilled and yields 3.9 parts of 7-(2',4'-dihydroxyphenyl)-3,7-dimethyloct-1-yl acetate b0.2 215° C. with the following percentage composition by weight:
