The invention relates to a method for continuously separating alpha-pinene and beta-pinene from turpentine. The method comprises the following steps: raw materials are subjected to a preheating treatment; a packed tower vacuum rectification process is carried out; alpha-pinene is collected with a reflux ratio of 8:1-10:1; a middle fraction is slowly collected with a reflux ratio of 20:1-30:1; beta-pinene is collected with a reflux ratio of 8:1-15:1; and when distillation is finished, while the rectification tower is not cooled and the vacuum state is not relieved, discharge is realized through the pressure difference between a tower kettle and a residual liquid tank. Therefore, intermittent distillation continuous operation is realized. With the method provided by the invention, the content of obtained alpha-pinene can be 98%, and the content of obtained beta-pinene can be 95%.
