This invention discloses a method for separating terpinene from camphor oil. The method utilizes the byproducts after separating eucalyptol from camphor oil. Camphor oil is subjected to vacuum distillation to release components, yielding passivated eucalyptol liquid and byproducts. The passivated eucalyptol liquid is then crystallized using a melt crystallization method to obtain more passivated eucalyptol and byproducts.
