I'm trying to find some literature on the subject of precipitating compounds that have been converted to a salt after being protonated with a strong acid (such as HCl, for example). I seem to be running into a wall once the salt is in the solution. I've tried searching via Google and Wikipedia, but I must not be searching for the correct terms because the majority of what I find covers precipitating proteins from solution, and don't seem to be relevant. The one document I found that seems to be decent is this PDF, which in the first sentence states:
I have undertaken a few experiments on the precipitation of salts from aqueous solutions by alcohol or acetone.
So that is a nice little bit of information - alcohol or acetone can be used to precipitate salts out of aqueous solutions. Unfortunately, the rest of the PDF isn't publicly available. And searching for using alcohol or acetone to extract salts from liquids seems to go back to the protein related results I mentioned above.
I don't have a specific compound or reaction in mind here, but rather a general inquiry on extracting salts that are the result of a base being protonated with HCl.
Question: Once a compound has been protonated with HCl and converted to a salt, what's the ideal way to precipitate said salt from the aqueous solution? Is acetone or alcohol the most sufficient route? Any links to some literature on the topic would be appreciated.
P.S. I'm not a trained chemist by any means (obviously). I'm a software engineer by trade, but I enjoy learning about organic chemistry as a hobby on the side.
