If a steam distillation is carried out using 10 grams of caraway seed, what is the typical weight essential oil of caraway that should be expected? (Give a range of weights)
Homework Answers
Caraway fruit usually contain 1-6% of their total weight as essential oils, this means that the least you would get from 10 grams is 1% of 10 grams: 0.1 grams and the maximum would be 6% of 10 g, which is 0.6 g. The expected range would then be:
0.1 - 0.6 g of essential oil.

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...

1. A student carried out a simple distillation on a compound known to boil at 124°C and reported an observed boiling point of 116°-117°C. TLC comparison of the product showed that the compound was pure, and a calibration of the thermometer indicated that it was accurate. What procedural error might the student have made in setting up the distillation apparatus? 2. Which method is better for purifying a mixture of two liquids that boil at nearly the same temperature: simple...
