1) You certainly DO NOT use the books sugested above!
2) Aspen used the REFPROP engine supplied by NIST. Better to go directly to NIST
3) Best is to use REFPROP which is based on reference correlations. For hexane we ha ve developed
Michailidou E.K., Assael M.J., Huber M., Abdulagatov I., and Perkins R. “Reference Correlation of the Viscosity of n-Heptane from the Triple Point to 600 K and up to 248 MPa”, J. Phys. Chem. Ref. Data 43:023103:1-13 (2014)
DOI: 10.1063/1.4875930
You can find values there. If you can not find it contact me ([email protected]) or if you just want two values contact me again. This way you will know that you have the best available data, and not tables of suspicious origin..
If you have thoroughly searched through the literature and could not find data, either experimental or calculated, then you would probably have to calculate yourself using some form of empirical correlation. Sources that I use for empirical correlations are as follows:
Hope this helps.
Other way to calculate these sort of properties is using HYSYS or ASPEN simulator using right property package/equation of state.
I recommend you to use the NIST Chemistry webbook where you can find various properties of compounds, from phase change data to thermochemistry data.

You can use simple software available on the internet named "Physprops", just enter the element or compound and give the desired pressure and temperature and find the required properties.
Experimental density and viscosity data at this temperature are available via the Dortmund Data Bank (www.ddbst.de)
