Khaira performed the synthesis of ester X. Liquid-liquid extraction is needed to extract compound X from the aqueous reaction mixture. Given the solubility of ester X in the following solvents. Solvent Solubility of Compound X (g/mL solvent) at 25°C water 0.278 ethanol 1.027 acetone 1.309 dichloromethane 0.891 diethyl ether 0.759 a. Which solvent must she use to extract compound X? b. Calculate the KD. c. She transferred all of the aqueous reaction mixture in a separatory funnel, and she added 100 mL of the BEST solvent (from question a). If the total volume of the reaction mixture is 100 mL, calculate the g of compound X that will be extracted. (Based on literature; 5.0 g of the product will be synthesized from the amount of starting material she used.)
Khaira performed the synthesis of ester X. Liquid-liquid extraction is needed to extract compound X from
the aqueous reaction mixture. Given the solubility of ester X in the following solvents.
Solvent | Solubility of Compound X (g/mL solvent) at 25°C |
water | 0.278 |
ethanol | 1.027 |
acetone | 1.309 |
dichloromethane | 0.891 |
diethyl ether | 0.759 |
a. Which solvent must she use to extract compound X?
b. Calculate the KD.
c. She transferred all of the aqueous reaction mixture in a separatory funnel, and she added 100 mL of the
BEST solvent (from question a). If the total volume of the reaction mixture is 100 mL, calculate the g of
compound X that will be extracted. (Based on literature; 5.0 g of the product will be synthesized from the
amount of starting material she used.)
d. Her partner, Jane, repeated the same experiment but this time, she performed the liquid-liquid extraction twice
using 50 mL of the BEST solvent (from question a). Calculate the g of compound X that will be extracted.
