“…6 Glycerol does not change the controlling mechanism for mass transfer. For air stripping of toluene, though the addition of glycerol decreases the infinite dilution activity coefficient of toluene, it will still be well above 100 at the highest proposed glycerol concentration, 7,8 which ensures liquid film control. For the reactive system, the effect of physical liquid film mass transfer (i.e., surface depletion of alkalinity) has been corrected in the kinetic model and is believed not to be an issue for the packed column experiments considering the relatively low CO 2 concentration and flux.…”

“…In our previous works [21,22] motivated by the problem of chemical denaturation and stabilization of proteins, the effect of six of the present additives (glucose, sucrose, ethylene glycol, glycerol, urea, and guanidine hydrochloride) on infinite dilution activity coefficient of aqueous toluene has been studied. It is interesting that also for this much more hydrophobic solute at subambient temperatures each of these additives exhibited a qualitatively same effect (salting-out or salting-in) as that observed for the two esters in this work.…”

“…7 However, the effects of these stabilizers vary among different proteins. With a view to enhancing the stability of therapeutic peptides and proteins, many studies have focused on the use of such drug-delivery systems as microspheres, nanoparticles, liposomal systems, and traditional emulsions.…”
