How do you dissolve anthracene?
Since anthracene is an aromatic hydrocarbon, I would suggest to try toluene as solvent, which is also an aromatic hydrocarbon solvent. According to the Wikipedia entry cited below, the solubility of anthracene in toluene is about 10 times higher than that in ethanol.
Why is methanol used for recrystallization?
Both ethanol and methanol are water like solvents (by virtue of the hydroxyl group); for this reason, and on the principle that like dissolves like, organic solutes should not have great solubilities in the cold solvent! Both alcohols are also cheap.
Is acetone a good solvent for recrystallization?
Acetone tends to be a good solvent at all temperatures; stuff will go up in it, and be reluctant to crystallize.
Why Is ethanol good for recrystallization?
Ethanol/water combinations are commonly used because ethanol has good dissolving ability for many organics, but is also infinitely co-soluble with water. Addition of water can rapidly and dramatically reduce the solubility of many organics and thus induce crystallization.
Is anthracene soluble in acetone?
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar….Anthracene.

Is anthracene soluble in ethanol?
Anthracene is insoluble in water but is quite soluble in carbon disulfide and somewhat soluble in ethanol, methanol, benzene, chloroform, and other organic solvents.
What is a recrystallization solvent?
Recrystallization is the most important method of purifying nonvolatile organic solids. Recrystallization involves dissolving the material to be purified (the solute) in an appropriate hot solvent. As the solvent cools, the solution becomes saturated with the solute and the solute crystallizes out (reforms a solid).
How do you choose a solvent pair for recrystallization?
For a two-solvent recrystallization, you should have one solvent (solvent #1) in which your desired compound is soluble at the boiling point. The second solvent (solvent #2) should induce crystallization when added to a saturated solution of your compound in the primary solvent.
What is the best solvent?
Water has the ability to dissolve a large variety of substances. This is the reason why it is regarded as a good solvent. Furthermore, water is often referred to as the “universal solvent” because it is known to dissolve more substances than all other liquid solvents.
