The catalytic isomerization reaction of α‐pinene to camphene over a clinoptilolite catalyst was investigated in a batch reactor open to the atmosphere between 130 and 155°C. The catalyst was selective to the isomerization of α‐pinene to camphene. The effects of several variables, such as reaction temperature, amount of catalyst, stirring speed and catalyst particle size, on the conversion of α‐pinene and selectivity to camphene were determined. The reaction fits a first‐order parallel reaction with rate constants of k 1 = 3.020·10 −2 e −33381.6/ RT for the production of camphene and of k 2 = 1.576·10 −2 e −31096.53/ RT for the production of limonene.
