[phantom19]

Hello..I am looking for UNIFAC-VLE Subgroup Parameters Table online but can't 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:

http://www.fsalazar.bizland.com/xls/UNIFAC.xls

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 don't 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!
