2,5-Hexanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 CH(OH)CH 3. It is both a glycol and a secondary alcohol. [1] It is a colorless water-soluble viscous liquid. [2] [3] [4] The chemical properties are well understood and have been extensively reported and studied. [5]
Polymerization-induced phase separation (PIPS) is the occurrence of phase separation in a multicomponent mixture induced by the polymerization of one or more components. [1] [2] The increase in molecular weight of the reactive component renders one or more components to be mutually immiscible in one another, resulting in spontaneous phase segregation.
Mixing of liquids A and B and subsequent phase separation When mixed, oil and vinegar will phase-separate A phase diagram for two isotopes of helium, showing at bottom a range of temperatures and ratios at which they will phase-separate. Phase separation is the creation of two distinct phases from a single homogeneous mixture. [1] The most ...
The aqueous phase is being drained into the beaker. A separatory funnel , also known as a separation funnel , separating funnel , or colloquially sep funnel , is a piece of laboratory glassware used in liquid-liquid extractions to separate ( partition ) the components of a mixture into two immiscible solvent phases of different densities . [ 1 ]
This happens because more of the light boiling substances are vaporized than of the high boiling substances and therefore the concentration of the high boilers increase in the liquid phase. A residue curve can also be constructed backwards and then moves to the azeotropic point or pure component with lower temperatures or higher vapor pressure.
The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The curves on the phase diagram show the points where the free energy (and other derived properties) becomes non-analytic: their derivatives with respect to the coordinates (temperature and ...
A theoretical plate in many separation processes is a hypothetical zone or stage in which two phases, such as the liquid and vapor phases of a substance, establish an equilibrium with each other. Such equilibrium stages may also be referred to as an equilibrium stage , ideal stage , or a theoretical tray .
However, when > /, there is separation into two coexisting phases, one richer in polymer but poorer in solvent, than the other. The unusual feature of the liquid/liquid phase separation is that it is highly asymmetric: the volume fraction of monomers at the critical point is approximately N − 1 / 2 {\displaystyle N^{-1/2}} , which is very ...
