HCID 14489Prenyl acetate

Procedure

Although the addition of acetic acid to isoprene in the presence of a catalytic amount of phosphoric acid will occur slowly at room temperature to yield prenyl acetate (systematically named as 3-methyl-2-buten-1-yl acetate), gentle heating of the reaction mixture in a pressure vessel at temperatures of approximately 40° C. to 100° C. is preferred if one wishes to conduct the process in several hours.
