Here's what I get
Explanation:
1. Requirements for a liquid/liquid extraction solvent
(a) Distribution Coefficient
The solute must be more soluble in the solvent (the extract phase) than in the raffinate phase (the other liquid).
(b) Insolubility
The solvent and the other liquid must be mutually immiscible. This means they will form two layers in the separatory funnel.
(c) Removability
It must be easy to separate the solvent from the solutes. This usually means the solvent must have a much lower boiling point than the solutes.
2. Extract layer
The density of ethyl acetate is 0.920 g/mL.
The density of water is 1.00 g g/mL.
The ethyl acetate layer will be on the top.
3. Separability of mixture
Two miscible liquids must have a boiling point difference of at least 40 °C to be separable by simple distillation.
4. Type of distillation
The boiling point difference is only 30°C, so you must use fractional distillation.
5. Apparatus
Your microscale kit must include an air condenser or a fractionating column.
Perhaps it looked like the fractionating head in the kit in Fig. 1.
The alternate distillation (simple distillation) would use a distillation head like that in Fig. 2.
