It was observed that the temperature shifts follow precisely the same Hofmeister series for anions that was originally found for salting-in and salting-out effects for protein solutions. The results are similar to the observations found for mixtures of water with non-ionic surfactants. In the case of dipropylene glycol propyl ether mixtures with water, temperature dependent phase diagrams in the presence of one salting-in (NaSCN) and one salting-out (Na2SO4) salt were measured at a fixed salt concentration in water of 0.041M. The results can be qualitatively understood by assuming a different hydrophobicity for both types of salts. They further hint at a strong degree of solute determined cooperative water structure. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Bauduin Pierre aut Wattebled Laurent aut Touraud Didier aut Kunz Werner aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/6/2004(2004-06-01), 631-641 0942-9352 218:6/2004<631 2004 218 zpch https://doi.org/10.1524/zpch.218.6.631.33453 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.6.631.33453 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Bauduin Pierre aut NATIONALLICENCE 700 1- Wattebled Laurent aut NATIONALLICENCE 700 1- Touraud Didier aut NATIONALLICENCE 700 1- Kunz Werner aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/6/2004(2004-06-01), 631-641 0942-9352 218:6/2004<631 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
