Sodium hydroxide + Acetaminophen= ?


Recommended Posts

What functional group is R-NH-C(=O)-R?


It undergoes characteristic reactions with strong bases and acids. Google' date=' grasshopper.[/quote']


Oh damn, no need to google this one. :P


Yeah, now that you think of it that way (the non- idiotic way), I'm guessing my products ought be sodium acetate (What could I use that for I wonder :rolleyes:) and p-aminophenol, which could be rather useful. P- Aminophenol would be insoluble, in water (which would be my solvent of choice for the [ce] NaOH [/ce]) so I can remove that to use in various organic syntheses, and then of course, anyone whose played with hot ice knows that it's properties are just plain fun! :D


Out of interest, are there any particularly interesting uses, whether as a reagent for organic synthesis or whatnot, for p- aminophenol?

where did you get a supply of pure acetaminophen?


Just a guess-


Cheapo uncoated off-brand acetaminophen tablets are not hard to come by and it's relatively easy to recrystallize. The fillers and binders are only a small portion of the tablet weight and are generally insoluble in most solvents.


Aspirin can be recrystallized in a similar manner, using hot acetone to extract the tablets. Slow evaporation gives large, transparent crystals in my experience.

Sorry for the late post... but yeah, UC got it right. I'm using tylenol, actually (not the vile suspension, but the tablets), which where I come from is easy to come by, and relatively cheap. Joy.
