Where to get UNIFAC Parameters Table?

  1. Feb 4, 2010 #1
    Hello..I am looking for UNIFAC-VLE Subgroup Parameters Table online but cant find any..where can I get it?

    By the way..how should I categorize C=C compound for example butene and compound like dimethylformamide when using UNIFAC VLE method?

    Thanks for helping...

    You can download an Excel table with parameters from my webpage in:


    That information was obtained from free VLECALC SOFTWARE.

    I need to find VLE data for 1,4,5,6 - tetrahydropyrimidine, 1,3-diaminopropane. For the second compound i can obtain UNIFAC parameters. But for pyrimidine, I dont know where to find it. In the link given www.fsalazar.bizland.com/xls/UNIFAC.xls, pyridine is given, not pyrimidine!

    Please help!

    Thank you very much!
