Hi I am currently working LIquid Liquid phase equilibrium data for my research work. I need information on binary or mutual solubility data or phase equilibrium data. Is there any method to get solubility between two organic compounds using HYSYS and/or UniSim? Please help on this topic. thanks a lot.

if you are doing a research in phase equilibria area you should consider access to Dechema, DDB or equivalent sources, many universities do offer that link
The softwares which you mention are not particularly powerful in this area, you may consider alternatives.

HI thanks I am doing research in liquid liquid extraction and need solubility data for solving some equations in the same. Is there any way i can get mutual solubility data for organic compounds like methanol, acetates, ketones etc from references or using excel sheets or any other options

As chemdoc said, your best choice for published mutual solubility data is going to be databases like the Dortmund Data Bank (DDB). If you don't have access to those databases, then you can use any databases you can access to search the open literature yourself. Of course, anyone can use internet search engines like Google to see what you can find on the internet, but it can be difficult to extract meaningful results from those searches.

using excel sheets or any other options

If you have interaction parameters for an activity coefficient equation (except Wilson, Wilson equation cannot be solved for two liquid phases), you can build a spreadsheet or other computer program to solve for the mutual solubilities. You should review your phase equilibrium/thermodynamics text for details on how to do this. Of course, the mutual solubilities calculated in this way will only be as good as the measured data on which the equation parameters are based.

If you don't have interaction parameters for an activity coefficient equation, you could use UNIFAC to calculate activity coefficients and phase boundaries, but they probably wouldn't be very accurate.
