应用解离萃取分离合成吡啶产生的3-甲基吡啶(3-MPD)与4-甲基吡啶(4-MPD)的混合物(φ(3-MPD)＝68.472 2%;φ(4-MPD)＝26.517 6%),对影响解离萃取分离的6个因素萃取剂、萃取剂的浓度及投料量、有机溶剂及投料量,以及分离温度进行了研究.选取了各因素的不同水平进行了六因素五水平的正交试验,以有机相两甲基吡啶的体积比为主要考查对象,筛选出了解离萃取分离甲基吡啶混合物的最佳工艺条件:当甲基吡啶的混合物为24 mL时,以浓度为2 mol/L的对甲基苯磺酸为萃取剂,用量为40 mL,正庚烷为溶剂,用量为48 mL,温度为0 ℃时分离效果最好.通过重复性实验,分离效果得到明显提高,说明此法具有工业化潜力.

计算机图形图像领域中,真实感只是计算机辅助人们表达场景的一种表达方式,能满足人的某一方面的需求(产生照片般真实的图像),从这种意义上来说,非真实感可以认为是计算机辅助人们表达场景的表达方式,每一种特定的非真实感风格能够满足人的某一或者某几方面的需求。真实感渲染追求的是逼真的模拟现实场景,而非真实感渲染追求产生一种与艺术家作品相近的艺术效果。
