3. (eg, Water can be a crystallization solvent between 0-100 o C; hydrocarbon solvents such as hexanes or petroleum ether have a different T range since they can be cooled below 0 degrees but boil below 100 degrees). Posted August 6, 2012. What will be the result of cooling the solution in this manner? The remaining two-component mixture in the ether layer can then be separated and 2- Ethanol, methanol, ethyl acetate, and hexanes are flammable and have moderate volatility, thus these solvents necessitate some different approaches than when using water as the crystallization solvent.
