Codeine Extraction from Perduretas

[mrbigsexy]

I was wondering if anybody had any specific information on codeine extraction from Perduretas specifically. If anybody is familiar with them, they contain only codeine as the active ingredient. So you don't have to deal with APAP solubility. Also, most of the other ingredients and binders seem to be fairly insoluble (It uses arabic gum, or something like that as the time release mechanism).

Anyway, does anybody have any specific experience with Perduretas? It should be simpler, if not, easier than the tylenol extraction, but I just wanted to check with others for advice and any other unforseen problems.

if your intent is codiene for oral use, toss all the pills in a beaker, cover with boiling water, allow the pills to dissolve, heat if necessary.

put beaker in fridge/freezer to cool to just above freezing, filter.

reduce volume by boiling. pour reduced liquid onto plate, evaporate under a small fan.

If you want codiene as a precursor, you will have to do an acid base extraction, and then preferably do a recrystalization or two

Theres no other active ingredient in that stuff but codeine. why do that. U cant shoot codeine even if u wanted too itl kill ya

It seems to me that the reason for doing this would be to defeat the time release mechanism.
Also, to prevent the same shit from being discussed yet again, i should mention that although there is no good reason to shoot codiene, some here have done so before with no ill effects

Just chew them and that will defeat the time release.

Does anyone know, if you extract the codeine and have pure codeine, can that be readily used as a precursor?

superman, if I did the acid/base extraction, wouldn't I just end up with the same product as I would with a cold water extraction? Just a little purer probably?

a cold water extraction will simply extract anything that's water soluble. not good enough for use as a precursor.

after you extract into cold water, and after you remove ALL the caffiene, there will still be contaminents.

So, dissolve your codeine in water, basify, add a non-polar solvent (something that dissolves codeine freebase readily), shake like a motherfucker, let sit for 15 minutes, separate the non-polar and save. repeat with fresh non-polar (NP), this time half as much. repeat again with fresh NP, this time 1/4 of the original.

now you have to freebase reay to be recovered fromt he non polar. how you recover it depends on the solvent you choose. don't use xylene or toluene because they don't evaporate so easily. you should confirm it, but if you use just the right amount of naptha (VM&P brand ONLY), such that at room temperature the naptha is near saturation by the codiene, you should be able to put the solution in the freezer for a day and since the lower temperature reduces the amount of material the solvent can hold, you will have codiene freebase that can be easily filtered out. (when filtering, always saturate the filter paper with the same solvent as being filtered. so in this case you would wet the filter with clean naptha. after wetting, put the filter+ receiving vessel in the freezer so as to reach the same low temperature at the solution you are filtering).

The above is one type of recrystallization proceedure, possibly one of the quickest and easiest there is. this method is ideal because it does two things for you at once; it lets you recover the freebase without evaporating a large volume of solvent, and it removes impurities by leaving them behind in the naptha.

now you can boil the naptha down a bit to reduce the volume, and freeze it again to recover some more codeine. there will in the end be some codeine left in the naptha. this is good though, because if you try to recover all of the codeine, you will end up pulling contaminants with it, and considering how cheap codeine is, you're better off with the minute drop in yeild in order to have a higher purity precursor

and that's one way of doing an acid base extraction! any more Q's feel free to ask

Why wouldnt a standard CWE work?

[superman]

because a cold water extraction doesn't remove certain inactives such as talc

So what your saying is that it wouldnt give you a relatively pure extraction? Like if you wanted to sniff them it wouldnt be a good idea cause of the talc. But it would till remove most of the APAP or Tylenol and basically give you a strong solution to drink? Ahhh damn...What im asking is if you use a standard CWE would you still retain most of the Codeine?

[superman]

CWE is sufficient if you're just going to use it, but he said "can that be readily used as a precursor?" and for that purpose, you have to remove all the garbage.

but ya, if you're just gonna use the codiene, don't sweat it, CWE is plenty

EDIT:

if you use a standard CWE would you still retain most of the Codeine?

yes, you should have damn near the theoretical maximum of the codiene.
