基于分子蒸馏的丙硫醚提纯工艺研究

Study on Purification and Purity of Propyl Sulfide by Molecular Distillation

采用分子蒸馏技术对市售的丙硫醚进行了分离提纯,考察了分离提纯的刮膜速度、蒸馏温度和蒸馏压力对丙硫醚纯度的影响,经过单因素分析,通过设计L_(9)(3^(4))正交实验,得到了分子蒸馏分离提纯丙硫醚的最佳工艺参数。

This paper the market propyl sulfide was concented by molecular distillation technology,The effects of scraping speed,distillation temperature and distillation pressure on the purity were investigated.Through single factor analysis and design of L_(9)(3^(4))orthogonal test,the optimal process parameters of molecular distillation separation and purification of propyl sulfide were obtained.
