摘　　要：对氢化松节油的减压精馏工艺进行了研究 ,考察了压强、温度、回流比、填料等因素对分离效果的影响 ;并对精馏操作工艺条件进行了优化 ,结果 ,蒎烷浓度达 96 % ;二次精馏后收率达73.0 6 %。The rectifying technology of hydrogenated turpentine under vacuum was studied. The effects of vacuum, temperature, reflux ratio, kind of fillers on the separation were investigated and the optimum technological conditions of rectifying operation were determined. Finally, the concentration of pinane reached 96%; the yield after 2 rectifications was 73.06%.
