molar mass determinationWe intend to divulge an easy experiment that permits the determination of molar masses of various compounds by cryoscopy. The major advantage of this is the use of the tert-butyl alcohol as a solvent, which requires simple apparatus and easy procedures. The melting point ...

It was observed a displacement of the binodal towards lower polymer concentrations when PEG molecular weights increased. On the other hand, the variation of pH did not promote significant alterations on the binodal. In the tie lines, it was not possible to stabilize the values of compositions ...
