2.2 Group 2 - chemrevise

Aug 02, 2016 2. The TiCl4 is purified by fractional distillation in an Ar atmosphere. 3. The Ti is extracted by Mg in an Ar atmosphere at 500 C TiO2 + 2 Cl2 + 2 C TiCl4 + 2 CO TiO2 is converted to TiCl4 as it can be purified by fractional distillation, TiCl4 being molecular (liquid at room temperature) rather than ionic like TiO2 (solid at room temperature).

Distillation - Wikipedia

Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). Dry distillation may involve chemical changes such as destructive distillation or cracking and is …

Membrane Scaling and Wetting in Membrane Distillation ...

Feb 11, 2022 Membrane scaling and wetting severely hinder practical applications of membrane distillation (MD) for hypersaline water/wastewater treatment. In this regard, the effects of feedwater constituents are still not well understood. Herein, we investigated how humic acid (HA) influenced gypsum-induced membrane scaling and wetting during MD desalination. At low …

Furthermore, such an ideal Rayleigh distillation is one where the reactant reservoir is finite and well mixed, and does not re-react with the product (Clark and Fritz, 1997). However, the term Rayleigh fractionation is commonly applied to equilibrium closed systems and kinetic fractionations as well (as described below) because the ...

Vacuum distillation - Wikipedia

Molecular distillation Molecular distillation is vacuum distillation below the pressure of 0.01 torr [21] (1.3 Pa). 0.01 torr is one order of magnitude above high vacuum , where fluids are in the free molecular flow regime, i.e. the mean free path of molecules is comparable to the size of the equipment.
