Abstract: ISOPRENE MAY BE PREPARED IN ONE STEP BY REACTING METHYLAL WITH ISOBUTENE OR BUTENE-2 IN THE VAPOR PHASE IN THE PRESENCE OF A CATALYST COMPRISING BORON PHOSPHATE. THE USE OF THIS CATALYST PROVIDES GOOD YIELDS AND SELECTIVITIES TOGETHER WITH REDUCED AMOUNTS OF ISOPRENE PRECURSORS WHEN COMPARED TO OTHER VAPOR PHASE PROCESSES.
