You have prepared a solution of water-soluble polymer, and wish to isolate the polymer from the water by freeze drying it. This process involves two steps
The temperature of the solution is dropped at ambient pressure to a temperature below water’s triple point.
The pressure of the frozen solution is reduced until water spontaneously leaves the system
With this above in mind, sketch a phase diagram of water showing regions of stability in its solid, liquid, and vapor phases. Then, on top of the phase diagram, draw a curve showing the temperature and pressure of the system as steps are carried out.

(1) Additives added to ethanol will have the same effect on boiling point as the same amount of additives added to water Ethanol changes its solution boiling point with additive mass fraction of 0.15 more than water changes its boiling point with a mass fraction of 0.25 If the activity coefficient of solute A in a solution is equal to 1, A has little to no preference to other molecules around it in solution It is likely that flavors...

For this problem, you are separating ethanol (more volatile) from water in three flash separators. The feed solution contains 100 mol/s with 30% ethanol by mole.The first flash unit is operated at 87 °F. The mole fractions of ethanol in the vapor phase and liquid phase are 0.42 and 0.09, respectively. The vapor stream leaving the first flash is then fed to a 2nd flash and the temperature is decreased to 83 °F.The mole fractions of the ethanol in the...

4. Construct a flow chart describing the separation of the mixture and the isolation of each compound in this experiment. A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction...

Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...

Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...
