A method for producing dipentene is given whereby a pinene-containing feed is isomerized at high temperatures in the presence of a small amount of a molecular sieve zeolite catalyst of the 13X-type which can be represented as follows: 1.0+/-0.2 M2O : Al2O3 : 2.5+/-0.5 SiO2 : y H2O wherein M is an alkali metal and y is a value from 0 to 8.
