In organic chem lab (steam distillation), the eugenol and water distillate you collect is apt to be cloudy, particularly the first part of this distillate. Please explain why.

Also, why does the eugenol move from the water layer to the dichloromethane layer during extraction?

Answer #1

The first fraction of the distillation will be water and the second fraction will be eugenol. It is because water (100 °C) is having the lower boiling point in comparison with eugenol (254 °C). In the first fraction, that compound will come which will have the lower boiling point.

As know, the solubility of water in the organic compound is significant. Since dichloromethane is an organic polar solvent so eugenol will transfer from water portion to it during extraction. It will because of more miscibility of eugenol in dichloromethane which may be due to like dissolve like principle.

Suppose you have discovered a new organic molecule and it is somewhat soluble in water even though it is more soluble in dichloromethane or ether solvents. If you do a single extraction, you get only 60% of your material to transfer from the water to the organic layer. How many washes would it take to extract over 90% of your organic material from the water layer. Explain.

In organic lab, we did a steam distillation of the essential oil of caraway oil. In the post questions it asks for some calculation I don't understand how to get. First ---> calculate the percent of essential oil based on the mass of caraway oil used (caraway oil used was 2.038 grams) Second ----> assuming the reaction is quantitative, the amount of carvone originally in the extracted oil can be calculated. The amount of limonene in the oil can then...
