Question 1.
According to Gay-Lussac's law: PT
i.e. P1/T1 = P2/T2
i.e. 760 mm Hg/(255+273.15) K = 25 m Hg/T2
i.e. The boiling point of Eugenol at 25 mm Hg (T2) = 17.37 K = 17.37-273.15 = -255.78 oC
1. Eugenol (clove oil) has a reported boiling point of 255° C at 760 mm Hg....
2. Aliquid mixture contains two substances whose boiling points are only 10°C apart. Which method of distillation should be utilized to obtain a clean separation of the two substances. Explain. 3. Which of the following pairs of liquids could be separated by simple distillation? Why? a. Ethyl acetate (b.p. 77°C) & Phenol (b.p. 181.7°C) b. Cyclohexane (b.p. 80.7°C) & Toluene (b.p. 111C) C. Hexane (b.p. 69.10C) & Ethylbenzene (b.p. 136°C) 4. What effect would (a) an increase or (b) a...

IlI. Preparation of Synthetic Eugenol (10 pts) Eugenol, the main component of clove oil, can be prepared from heating 2-allyl guaiacol (in the absence of oxygen) to temperatures>205 °C. In practice, however, it is most cost effective to extract eugenol from cloves, its natural source. Given a weight percentage of eugenol in cloves at-15%, calculate the minimum mass of cloves one needs to obtain 1.00 g of eugenol as product? Report your answer below. Show your...
