I have an unknown mixture of Benzoic acid, Dimethyl Terephthalate, and Naphthalene dissolved in Dichloromethane. I need to separate the mixture to find the composition using some sort of acid base reation and a distillation. How would I do that? I think that I could use steam distillation to remove the naphthalne but im not really sure on that. Any help would be apprectiated. I start with 25mL of the unknown mixture.

4-bromobenzoic acid (1.0 g) is dissolved in 20 ml dichloromethane. After addition to a separatory funnel, the dichloromethane solution is treated with 20 ml 3.0 M NaOH solution. After the layers are separated, which layer(s) will contain an organic compound (non-solvent)? What would happen if the aqueous layer is treated with 20 ml 3.0 M HCl?

The Separation of Three Organic Compounds by Acid, Base Reactions and Liquid, Liquid Extraction. Okay, so we had solid benzoic acid, ethyl 4- aminobenzoate, and 9-fluorenone all dissolved in diethyl ether. We separated the basic component by adding 3M HCl, we separated the acidic component by adding 3M NaOH. I don't understand what happens here. To isolate the acidic solution, we added 6 M NaOH and used the vacuum to recover the solid. To isolate the basic solution we added...
