Question 6 (10 pts) Steam distillation can be run more efficiently in some cases using super-heated steam at 1 atm pressure rather than boiling water. By increasing the temperature of the steam beyond the boiling point of water in a controlled fashion, the oil may still be protected from degradation while increasing its contribution to the vapor composition, making the process more efficient. At 150 °C, linalyl acetate exerts a vapor pressure of 93 torr. If a steam still were...

An experiment performed using solid to liquid extraction, liquid-liquid extraction, heating, and recrystallization to isolate caffeine, was not totally successful due to their being very little to no product of caffeine left when the time came to recrystallize the pure caffeine. During the experiment what could of caused there to be not enough caffeine to recrystallize it? ethyl acetate was used as the organic solvent hexane and acetone was used to recrystallize the crude caffeine, through mixture and boiling. Could...
