Abstract: In order to study process conditions of separating high-quality linalool, and investigate the relationship between purity of linalool and energy consumption, the equilibrium relationship of linalool and the other main components in Cinnamomum camphora leaf essential at the pressures of 1 kPa was analyzed by Aspen Plus software, separating models of single-tower and double-tower were established, and separating process of linalool from C. camphora leaf essential oil was simulated. The productions with 95.4%and 99%of linalool were obtained, and heat duty of double-tower distillation was 2.6 times as much as that of single-tower distillation. The results showed that camphor content in linalool products was the key factor affecting the distillation process parameters.
