6. a. A mixture of 60 mol % n-propy!cyclohexane and 40 mol % n-propylbenzene is distilled through a simple distillation apparatus; assume that no fractionation occurs during the distillation. The boiling temperature is found to be 157。C (760 torr) as the first small amount of distillate is collected. The standard vapor pressures of n-propylcyclohexane and n-propylbenzene are known to be 769 torr and 725 torr, respectively, at 1573 °C Calculate the percentage of cach of the two...
can you please help me to calculate volume percent of methanol for simple and fractional distillation. please, show me how you calculated. Simple distillation: mixture of 1.5 ml of ethanol and 6 ml of isopropanol. refractive index of mixture before distillation 1.368, after distillation 1.3533 fractional distillation: mixture 1.5 ml ethanol and 6 ml of isopropanol refractive index of mixture before distillation 1.368, after distillation 1.3455
Isolation of eugenol lab by extraction and simple distillation 20ml of dichloromethane (1g clove oil / 10ml dichloromethane) solution I'm supposed to calculate the percent recovery of Eugenol in this mixture . However imnnot sure how I'm supposed to go on about it. Initial weight of flask(empty) was 39.8g Final weight of flask (with eugenol) 40.4g How am I supposed to calculate the percent of eugenol obtained if I don't know how much clove oil I obtained as well. Am...
Pre-lab questions 1. What is the basis for separation of compounds using distillation? Why is it possible to separate ethanol from water using distillation? 2. What is the difference between simple and fractional distillation? Why does fractional distillation give a much better separation of substances? 3. When is vacuum distillation used, and why is it used? 4. What is an azeotrope? How does this apply to the separation we are doing in this experiment? 5. What intermolecular forces are being...
Why does fractional distillation result in more pure products but lower yields? Can simple or fractional distillation result in distillation of pure ethanol? Explain.
In a simple distillation of brewed coffee, what can we expect the distillate to smell like? Why?
2. Explain why the vacuum distillation has more advantage than the simple distillation? 3. Give two examples of materials that can be purified by steam distillation. 4. What are the first and second yellow solids in this experiment?
