Le. Roy et al., Thermodynamics of mobile order theory. Part 4. Comparison of experimental and predicted solubilities for trans-stilbene, PHYS CHEM L, 38(3), 2000, pp. 333-343
Experimental solubilities are reported for trans-stilbene dissolved in sixt
een organic solvents at 25.0 degrees C Solvents studied contained chloro-,
cyano-, hydroxy-, fluoro-, and ether-functional groups. Results of these me
asurements, combined with previously published solubility data, are used to
test the applications and limitations of expressions derived from Mobile O
rder theory. For the 34 solvents for which predictions could be made comput
ations show that Mobile Order theory does provide fairly reasonable (althou
gh by no means perfect) estimates of the saturation mole fraction solubilit
ies. The average absolute deviation between predicted and observed values i
s circa 20%. The deviation increases significantly to 1,210% when ideal sol
ution behavior is assumed.
