CO2 technology processes extraction efficiently as it is a good solvent because it is easy to make it change phases with relatively low temperature and pressure. It can also sublime at 1.01 bar and the triple point is at 5.2 bar and -56.6°C. If the temperature and pressure increase to the critical point at 73.8 bar and 31°C, CO2 exists as a supercritical fluid and has properties of both a liquid and a vapor.
Dry ice sublimes at atmospheric pressure and temperatures above -78°C. If the CO2 is sealed during sublimation, the internal pressure in the vessel increases. After the temperature and pressure have increased, liquid CO2 forms.
what are the properties of liquid co2 that allowed it to extract the limonene from orange...
1. what are the properties of liquid CO2, that allowed it to extract the limonene from orange peel? 2. List four mist abundant complunds in orange oil and their relative amounts. 3. if you were to see a peak in your GC-MS sample with a retention time of 8.00 min, how would the polarity of that compound compare to the polarity of limonene? Explain. 4. what is the purpose of adding the anhydrous sodium sulfate to GC-MS vial and filtering...
what is the purpose of steam distillation and why is it used instead of simple distillation in limonene extraction from orange peel
From a molecular perspective (not from a green chemistry perspective), why is liquid CO2 a good solvent for limonene?
What organic compounds are present in orange peels (other than limonene)?
Limonene smells strongly of oranges and is a liquid at room temperature and pressure. What are the components of the internal energy that would be nonzero for liquid limonene at room temperature? Choose from: translation, rotation, vibration, van der Waals, charge-charge, dipole-dipole, bond, angle and dihedral.
Post lab question help. This lab was about extracting limonene from orange peels. Chemical tests were then done with limonene using Br2 and MnO4. a. A pure sample of (R)-limonene has a specific rotation of +125.6". If a sample had a specific rotation of +80.4º, how much of each enantiomer is present in the sample? Show your work b. Why is a large excess of water used in the distilling flask in the steam distillation of limonene? c. After your...
2. What organic compounds, other than limonene, may bepresent in citrus peel? 3. Write the chemical reaction of limonene with bromine. Show a mechanism and name the principle product(s).
