WebDec 8, 2024 · 4. Phase diagrams. The phase diagram shows the domains occupied by the different phases of a system, the boundaries that separate these regions and the special points of the system, as a function of two independent variables. A practical choice of these variables is that of pressure (P) and temperature (T), which can be measured … WebJun 15, 2001 · The distinct features of the phase diagram for the polyimide/DMSO/water system are: (1) extremely narrow miscibility gap, (2) close gelation point to the binodal curve, and (3) almost parallel tie-line passing through the gelation point to the polymer–solvent axis. These properties hinder the phase separation process to proceed … frederick bailey and huldah mcconnell

WebApr 22, 2016 · Rasmussen and MacKenzie reported a phase diagram of temperature and composition ratio for the DMSO/water system [18] . This phase diagram was further investigated in more detail by a number of authors experimentally as well as by computer analysis in order to elucidate the lower-temperature region below about −60˚C [19] - [28] … WebBecause of the relative volatilities of a DMSO-water system, distillation losses in a well-designed system should not exceed 1% of the DMSO feed. The overall recovery of DMSO will depend on the character and quantity of impurities present but should exceed 95-99% of the feed. A typical recovery system is shown in the adjacent diagram (Figure 3). frederick baird
