What is the ideal solvent for Phenanthrene if you're trying to isolate and crystallize it?
what are the properties of an ideal recrystallization solvent?
Extracting Phenanthrene - can't use HCl because Phenanthrene is not soluble in HCl, so what can I use?
1.) What is the ideal solvent volume for heating under reflux?
Why is EtOH not ideal for the Williamson ether synthesis? What would be a better solvent choice? Why isn't the better solvent choice used on a large industrial scale? Consider the cost and waste disposal.
(1) For crystallization in lab, What is the best solvent to use for: Methyl 4-aminobenzoate and Phenanthrene (2) Also, why are the chosen solvents the best for their crystallization? My lab only has methanol, water, toluene, hexane, methylene chloride, or ethanol. could you choose the best from these?
1) what is the benefit to performing a recrystallization to isolate a product as opposed to simply evaporating the solvent and recovering the product? 2) what shoul melting point always be reported as a range rather than as a single temperature?
Generally, what is the ideal Rf value of the analyte when using TLC to choose a solvent for column chromatography?
3. Instead of trying to isolate the more soluble (S)-aminium-(S)-malate diastereomers from the mixture of diastereomeric salts, what would be a better way of ensuring that the (S)-(-)-amine diastereomeric salt crystallizes preferentially as the less soluble crystals? Hint: What is the enantiomer of the (R)-aminium-(S)-malate diastereomer and how could it be formed?
