Can isobutyl oleate crystalize out of a solution, at -18 degrees celcius? if so, which solvent?
Accepted Answer
Isobutyl oleate's crystallization behavior at -18°C depends on the solvent. Here's how to approach this question:
1. Solubility: Isobutyl oleate is likely soluble in organic solvents like hexane, diethyl ether, or toluene. Its solubility in water is very low. To crystallize it, you need a solvent in which it is less soluble at -18°C than at room temperature.
2. Solvent Choice: A solvent like hexane would likely be suitable. Hexane is nonpolar and isobutyl oleate is nonpolar, leading to a higher solubility. However, as temperature drops, the solubility of isobutyl oleate in hexane would decrease, potentially leading to crystallization.
3. Crystallization Process: To crystallize isobutyl oleate, you could dissolve it in hexane at room temperature and then slowly cool the solution to -18°C. The decreased solubility would cause the isobutyl oleate to precipitate out as crystals. You could then separate the crystals from the solvent by filtration.
