I figured it out. I'm just a noob as usual. The valves that control the vacuum just pull in outside air, causing ether to leak.

I believe it should work fine, yes, but oxycodone is not a phenol. I assume you mean oxymorphone. If not, consider this review: Recent advances in ether dealkylation.

Since K2CO3 releases water on protonation, using an excess of acyl halide may increase yield. I have also seen pyridine used: http://www.orgsyn.org/orgsyn/prep.asp?rxntypeid=117&prep=CV9P0507

Aniline and piperidine will be acylated. You need a tertiary amine, if that is the road you choose to travel.

If your goal is to acylate the 6-keto moiety, yielding an enol ester, you should use pyridine if possible, though it's possible carbonate could work with some sacrifice in yield. Better may be to use propionate salts to generate propionic anhydride in situ and also to act as a base.

Abstract

14-Acetoxydihydrocodeinone enol acetate (I) and 3-acetyldihydromorphinone enol acetate (II) were prepared and biotested.

Dried dihydrohydroxycodeinone in Ac2O was refluxed with AcONa at 160-70°C for 2 1/2 hours, cooled, the excess Ac2O removed, the acetylated base precipitated with diluted ammonia with agitation at under 15°C, kept standing, filtered, and recrystallized, giving 88-90% I, mp. 209-10°C (from EtOH); 1 part was soluble in 30 parts of EtOH, 2 of CHCl3, 4 of C6H6, 100 of ligroine, 100 of Et2O, and 50 of Me2CO (at 20°C).

update, dissolved some silver nitrate in ethanol, took time, then added that to small amount of sample, blackish color ppt. I initially thought of disolving the silver nitrate into water, but if a silver halide gets formed, it to would disolve in the water, so changed to dry as poss (non sodium methods) ethanol. Took abit to disolve, but finally did and the black ppt took 20 odd minutes.?

That would be denatonium. 10ppm is intolerably bitter to most.

Xanax, Ambien, and Benadryl are all very bitter, but there's different qualities in the taste.

Why mess about with stuff that has a good purpose like xanax,ambien etc...

As assyl fartrate stated denatnium will do the job like nothing else. In my country its used in anything that you can get drunk/intoxicated with, as ethanol or methanol or any kind of alcohol which are not meant for consuming and sold/taxed by the state (IPA excluded). I think, almost sure, its also used in such a thing as the colourless nail polish you put on kids nails when you want them to learn not to bite them.

Hey guys, I have another vacuum related question, what type of oil goes in to an oil (vacuum) pump fron a lab. I was thinking of using compressor oil.

Refrigeration compressor oil will work quite well, but you really need to start doing your own research:

instead of expecting some one else to do it for you     The end results from the effort applied   

What you choose???

And for Al/Hg, What is the rate of Al/Nitro compound without the famous double bound?? It would be run just in IPA or Methanol instead of AcOH/IPA  like nitroalkenes?

As you were told already in:

you are making a nuisance of yourself    As mentioned in:

https://the-collective.ws/forum/index.php?topic=9679.0

spoonfeeding is contrary to your personal development in learning chemistry    Clandestine Chemistry is simply too dangerous for short cuts    As far as the Christmas reduction:

should have been memorized by now    An old Hive thread about the subject in question has been posted:

https://the-collective.ws/forum/index.php?topic=23176.0

so there had better not be any more questions about this particular subject in this thread    There's no way anyone can choose what's best for you since circumstances can differ greatly  The end results from the effort applied 

I have a question about grignard suited solvents: I want to use DIPE, diisopropyl ether, to substitute diethylether with because it sucks to get the latter as i have to pick it up in person from holland if i want to get more than a quart liter, and without getting pretty much embezzled from the local pharmacys.
I dont think the schlenk equilibrium will lead to a different favored alkylmagnesiumbromide in both solvents, that means they are interchangable there, am I right on this one? Both are monoethers, and Ive seen only triethylamine and dioxane so far giving another formula of alkylmagnesium halide, and both are substantially very different to a monoether like Et2O or DIPE, so thats where i need affirmation please.
I would also likely use another well suited solvent, like THF of course. Has anyone first hand experiences with grignards using other solvents as Et2O? Pyramid, you were meant, chime in and tell!

And I do have another question, how do I keep DCM from giving a small second layer on top of the solution thats getting extracted? It really bothers me all the time it is doing this and salting out doesnt work, in acidic solutions too.
Cooling it very muich also doesnt help.
Maybe adding a bit of a solvent miscible with DCM but less dense than water will collect the tiny upper DCM layer, and will dissolve it in the main portion DCM on the ground?
Also i got a bit carbon monoxide poisoned once I worked with DCM, everybee working with it and does stuff like redistilling large amounts of it without a fume hood should bee aware it gets metabolized into CO which is toxic like HCN, when accidentally inhaled.

Does anyone have idea how to separate DAM aka. heroin from caffeine!?

I stumbled upon source of great quality 50/50 DAM/Caffeine and was promissed to get a free sample if I help
to separate it and get 100% pure DAM.

Now i know that DAM is in freebase form but I am not sure about caffeine.
I know that DAM freebase is not very soluble in water while caffeine is,so this might do a trick.
Shake it in the warm water,caffeine should dissolve leaving DAM to be filtered.

Does anyone have an idea if this will work or what other solvent to use?!

Vice versa or dissolving DAM while leaving caffeine is good idea too if someone knows how to do it.
