计算溶解度、活度系数时,混合溶剂超过5种怎么办?

可以先设置5种混合溶剂,File → Save as保存作业,然后File → Save runfile得到一个*.run文件,里面类似有如下关于溶质、溶剂的描述(可以看到总共6物质,不过下面列出了8种物质,七种为溶剂、一种为溶质):

Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/1-Hexene.coskf" 
  frac1 0.1 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/Vinylacetonitrile.coskf" 
  frac1 0.1 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/1,2-Benzene_dicarboxylic_acid,_heptyl,_undecyl_ester.coskf" 
  frac1 0.1 
  nring 6 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/1,1,2,2-Tetrachloroethane.coskf" 
  frac1 0.3 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/1,2-Epoxy-3-phenoxypropane.coskf" 
  frac1 0.2 
  nring 9 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/1-Hexanol.coskf" 
  frac1 0.1 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/Benzene.coskf" 
  nring 6 
End 
Compound "D:/AMS2024.101/Packages/AMS2024.1.packages/adfcrs-gs907vlr/content/ADFCRS-2018/Water.coskf" 
  frac1 0.1 
End 

这里是将溶质、溶剂一起列出来的:

  • 每种物质以Compound开头,以End结尾
  • frac1描述混合溶剂的摩尔比,没有frac1 数据的,则为溶质(因为这里采用的是无限稀释模型)
  • nring描述物质的芳香环数量。这个值在COSMO-RS主窗口 → Compounds → List of all added compounds 的化合物列表中,点击每种物质,右侧的Nring栏目,后面有Generate选项,点击即可生成
  • 注意修改溶剂的摩尔比到合适的值,溶质摩尔比加和为1.0

修改完毕,保存,然后在AMSJobs窗口,可以选中该作业,然后Job → Run运行之。结果在SCM → output打开的*.out文件中,类似如下内容:

其中DENSITY这一行可以忽略不看,component列显示7表示7种溶剂混合。
