With the purpose of establishing an application method,studies on the catalytic transformation of 3-carene were carried out. The results indicated that metal catalysts,especially the platinum,had excellent ability to promote the ring opening and dehydrogenation of three-membered ring in 3-carene. With platinum-catalysis,the selectivity of dehydrogenation product cymene exceeded 90% and the mass ratio of m-cymene to p-cymene was nearly 7 ∶ 2. The ring opening and dehydrogenation of 3-carene could be similarl...
