Dr. Sereda, what are desirable characteristics of solvents for recrystallization (Higher solubility at higher temperatures and lower solubility at lower temperatures, non-reactivity with the compound, ease of removal, but other scenarios are possible. - GS). and extraction? (Higher solubility of the desired compound and lower solubility of non-desired compounds, immiscibility with the liquid you are extracting from, non-reactivity with the compound, ease of removal. - GS)
