Procedure
Analogous with Example 1, a solution of 5.6 grams (0.08 moles) of isoprene and 100 milliliters of a 65 volume percent aqueous propionic acid (mole ratios: water to isoprene=24.3, propionic acid to isoprene=10.7) was reacted in the presence of 5 grams of a cation exchanger sold under the trademark Lewatit SPC 118 at 35° C. After stirring at 35° C. for 6 hours, the reaction was 20 percent complete. There was obtained 2-methyl-3-butene-2-ol with a yield of 57 percent and prenylacetate with a yield of 29 percent.
