What solvent or combination of solvents should I use to recrystallize 1,4-dichlo

Question

What solvent or combination of solvents should I use to recrystallize 1,4-dichlorobenzene and ethyl 4-aminobenzoate? I was thinking hot water and ethanol for 1,4 dichlorobenzene, and just hot water for ethyl 4-aminobenzoate, but would like some reassurance for my lab practical tomorrow. Or maybe I should just use hot ethanol as my solvent for ethyl 4-aminobenzoate. Also if I used hot water AND ethanol as my solvent for 1,4 dichlorobenzoate, what is the ration I would want to use?

Solubility Information (Useful when choosing a solvent for recrystallization) 4-chloroaniline and ethyl 4-aminobenzoate are insoluble in cold water, but somewhat soluble in hot water . 4-chloroaniline and ethyl 4-aminobenzoate are soluble in ethanol 4-chloroaniline is soluble in most common organic solvents Naphthalene is soluble in hot methanol and virtually insoluble in water 1,4-dichlorobenzene is soluble in hot ethanol and virtually insoluble in water

Explanation / Answer

As both 1,4-dichlorobenzene and ethyl 4-aminobenzoate are soluble in hot ethanol and ethanol respectively. So you can use ethanol for their recrystallization. What you need to do is that first dissolve in hot ethanol, once it dissolves, keep it in cold ice immediately. So you will get the crystal, sure.

Yeah as you are thinking hot water for 1,4-dichlorobenzene that's good. but the solubility is not so good. that's why it's better to go with ethanol (Organic Solvents)

Yeah...!!! You can just use hot ethanol as your solvent for ethyl 4-aminobenzoate crystallization.

If you use hot water AND ethanol as a solvent for 1,4 dichlorobenzene, I will suggest you go with ethanol, not hot water. because it is not well soluble in hot water.
