摘　　要：粗硫酸盐松节油是硫酸盐法制浆生产的副产品，因其含有许多硫化物故有恶臭味和较深的颜色，不能直接使用．为扩大其用途，须对其进行精制．本文通过正交实验得出：先用多种酸进行预处理后。Raw sulfate turpentine is by-product of kraft pulp mill,. which has some kinds of sulfides in it. Owing to its yellow color and its stink odor, it cannot be used directly . To expand its application, it must be refined to deodor and decolor. Based on orthogonal experimental program, the optimum process and technic condition are obtained in this study.The optimum process is as follows: firstly treat it with mixed acids , then treat it with peroxide hydrogen (4%), finally distillate it with steam .
