Hey guys,

I have looked this up alot and have yet to find an explanation of what the point in first dissolving your codeine/apap pills into hot water and then lowering the temperature. From the information I have read, APAP has a better solubility in hot water and codeine has a slighly worse solubility in hot water. So why not just dissolve the pills in cold water from the beginning?

I read the table on erowid about solubility. I interpet it as saying that, eg. 1g APAP will dissolve in 150ml 21C water, does this mean that you would need say 300ml 21C water to dissolve 2g APAP?

If anyone KNOWS of any resources that explain the chemistry of the CWE in depth, I would appreciate sharing it with me. I have searched this alot, I'm not asking anyone to do the homework for me, if you don't know the answer to my question or of any websites that do, then no problem.

I was also think of evaping my product so that I may press the powder into pills, or put in capsule as I much prefer the high from pills than drinkjing the solution, anyone done, any thoughts?

Thanks for any help all,
leroche

You want as much of the pill dissolved just to be sure you got all the codeine. You could use room temp. water, but it would take more effort (stirring, waiting, etc) to dissolve the pills.

Yes.

It's basically a recrystalization, wikipedia actually has a pretty good article on it, better than most of their pages. http://en.wikipedia.org/wiki/Recrystallization

That would work fine, but to press a pill you need to mix it with binders and put it in a pill press, too much effort IMO, capsules would be smart though.

Thanks DiamondX,

This is a perfect response. :-)

No problem, also, keep your opiates away from heat if you evaporate, I learned the hard way :(

Does anyone know why codeine is less soluble in a warmer solvent??

I actually found that hot water destroy's the effect and that room temp. water is more effective.

Is it?

The only time I have seen a CWE get evaporated (I didnt see the process just the end product) it was a brown goo.

My friend told me it is maybe because of the caffeine in T3's

Did he use too much heat?

I don't mind codeine at all for recreation, and it is great for pain, and since I am in canada, I can have as much as I want OTC. So, knowing that I can evap to a powder is fucking awesome, I would love to have pure-ish codeine capsules.

Is it?

According to a chart on Erowid:

Codeine
Solubility (31C water) - 1g / 2.3 ml // Solubility (21C water) - 1g / 0.7 ml
Typo or..?

Edit: Also, it's only peculiar for the "Codeine" type of codeine, whatever the fuck that means. Here's the actual link. (http://www.erowid.org/pharms/codeine/codeine_faq.shtml)

I did the evap and the water evaped completely after about 10 hours, after 48 hours it was completely dry (as in no goo or anything). And this is with no heat or light.

Using heat and light is completely unnecessary as previously mentioned. I out in capsuels and swallowed. Within 40 minutes a started to really feel it, and was peaking for about an hour. Good stuff. Doesnt hit you anywhere near as hard or fast as solution, but lasts much longer. I'm doing it again.

I'm not convinced that this is right, though it's repeated on several other sites...

I've had trouble finding an actual value for the solubility, but here is one which (I think!) indicates that the phosphate is more soluble in hot water. (http://tinyurl.com/7e8clz) I assume the ratio indicates the minimum volume of water which 1g is soluble in, though I may be wrong...

I dont believe it either. Would the numbers make more sense if they were they other way around

Well, that varies wildly on a number of conditions, actually. Since we're not driving unbound gases out of solution, we'll focus on what matters - the thermodynamics of dissolution...

I forget which goes what way, but suffice to say, the rest energy of dissolution can be an exothermic, endothermic, or thermodynamically neutral process. The dissolution of ammonium chloride will serve as a mild refrigerant, for instance, and similarly, the precipitation of supersaturated sodium acetate is the basis for many a heat pack, I believe... and despite these charming examples of individual ions, sodium chloride is fairly thermodynamically neutral - and behaves like it.

The thermodynamically neutral highly-polar salts tend to have a flatline dissolution curve. Like I said, I can't recall and don't care for the life of me at the moment which is which, but solute of endothermic and exothermic dissolution will have acending and decending temperature/solubility curves, oddly enough.

As one can imagine, if the gods of physics grant you luck, this can make for truly fuckin' bitchin recrystallizative purification of either acids or bases, if you can find a counterpart ion which gives the target compounds inverse thermodynamics - dissolve in lukewarm solution and collect crystals on both ends. Takes a lot of fuckin' luck, though, since the non-target additive will have to be the same for both compounds.
