Analogous with Example 1, a homogeneous solution of 5.6 grams (0.08 moles) of isoprene and 10 milliliters of a 75 volume percent aqueous acetic acid solution was reacted at 40° C. in the presence of 5 grams of a cation exchanger sold under the trademark Lewatit SPC 118 (mole ratio of acetic acid to isoprene 15.6 to 8.7; mole ratio of water to isoprene=17.3). After stirring at 40° C. for 6 hours, the reaction was 73 percent complete. There was obtained 2-methyl-3-butene-2-ol with a yield of 48 percent, Prenol with a yield of 2 percent, and prenylacetate with a yield of 30 percent.
