Witryna11 paź 2010 · Therefore, it is very important to identify any possible hydrate form (s) in the early phases of the drug development process. Water is frequently present in the manufacturing environment of pharmaceuticals, for example atmospheric water cannot be avoided and aqueous processing solutions are needed. WitrynaStudents remove the water of crystallisation from hydrated copper(II) sulfate by heating. Condensing the vapour produced in a second test tube collects the water. The white anhydrous copper(II) sulfate is then rehydrated and the blue colour returns. This experiment can be carried out in pairs by students. It should take no more than 30–40 ...
Witryna16 kwi 2012 · CO2 hydrate formation and dissociation is crucial for hydrate-based CO2 capture and storage. Experimental and calculated phase equilibrium conditions of carbon dioxide (CO2) hydrate in porous medium were investigated in this study. Glass beads were used to form the porous medium. The experimental data were generated using a … WitrynaSubstances that spontaneously absorb water from the air to form hydrates are known as hygroscopic or deliquescent, whereas hydrates that lose so-called water of hydration …
