Study of Differences and Similarities between Polymeric and Ionic Liquid Aqueous Solutions in Respect to Salt Effect and Liquid – Liquid Equilibrium

In this paper, salting-out principle was used to produce new types of polymerbasedaqueous biphasic systems (ABS). For this purpose, the process of cloud pointof polypropylene glycol 1000, a temperature sensitive polymer, is in pure water andin aqueous solutions with various molecules of salts ( Na2CO3, Na2SO4,Na3Cit,K3Cit, NaCl DTAB,SDS) and to be investigated hydrophilic andhydrophobic ionic liquids ) with a specific moleality 0.05 ( C2mimBr, C4mimBr,C8mimBr, C8mimCl, C4mimBF4, C4mimPF6)The thermodynamic quantities of the clouding process have been calculated andalso the salt effect of stabilization (salting out/ salting in) has been evaluated usingthe Setschnow equation.Observations indicate that salts (Na2SO4, Na3Cit, K3Cit,Na2CO3) show a reduce clouding temperature [1-3].
