Codeine --> oxycodone Has anyone thought about this going through 14-hydroxydihydrocodeinoneas an intermediate? The process seems pretty easy, the only bad thing being Cr which can be get rid of. I think you could create H gas too with out much hassle...

Theres gotta be a "lab" way to do it....
Dihydrocodeine is basically just a little bit stronger than codeine, and from what a few times, and even when i didn't have much of a habit at all, all they seemed to do was keep me.

This is best done by using a Zippo, or by having someone it it .
DO keep it heated to boiling the entire time.
Keep the flame on the spoon while the pill breaks down.
DO NOT LET THE WATER COOL DOWN.

Ok so in our lab, we were given 8g of a mystery powder. The powder is probably a weak acid.
The tools we have available to determine its identity:
ph paper, ph meter, phenolphthalein, bromocerol purple, bromocerol green.
A buret, graduated cylinders, ...

If the acid is polyprotic I doubt you you will need at least some meaningful change in pH, so keep adding the material until it changes is probably a weak acid.

I'm not even gonna go into plugging when you're confused about PH and chemicals like NAOH and HCL, both of these can be very dangerous.

What I thought: Higher temperatures increase likelyhood of SN1 and E1 reactions because the higher temperature helps stabilize the carbocation.
A passage i'm doing says that higher temps increase likelihood of elimination reactions.

To be in acidic conditions, so even though you're raising the pH, it's hardly like you're in 50% NaOH the pH, it's hardly like you're in 50% NaOH.

According to berkely review:
"a weak base and a strong base of the same concentration require the same moles of acid to be neutralized...because the moles of hydroxide are the same for equimolar bases, regardless of their strengths"
Could someone explain...

If the desired pH is 7 'strength', a stronger base will release more OH- into solution and keep less in reserve, while a weaker base will release less....
Into hydroxide?
Thanks! Neutralization just means acid + base reacting to form a salt .
