Web1 nov. 2005 · The function of amphiphiles is based on the need to hide their hydrophobic parts from the hydrophilic solvent. Low concentrations of surfactant dissolve into water as monomers and coat the surfaces of the container, but above a certain concentration called the critical micellar concentration (CMC), aggregates start to form. WebIn this context, a new class of solvents is emerging: switchable solvents. Switchable solvents (SSs), first reported by Jessop and Liotta, are liquids that can be converted from a nonpolar form to a polar form and vice versa. The switching of the solvent in the hydrophilic form (switch forward) is done by bubbling CO 2 through the solvent.

Weball deep eutectic solvents are hydrophilic and are limited in applications that require high basicity and low water content such as liquid–liquid extraction (LLE). The concept of DES in extraction is still in its infancy [20] compared to ionic liquids, nonetheless, the increasing number of yearly publications make the field very promising. WebIn hydrophilic polymers, water partially crystallizes below 0°C only if its concentration is greater than a critical value, C ∗ . When crystallization occurs, the glass transition, Tg, of the polymer solvent matrix remains constant. This Tg …
