oh no! not another pill extraction post

[interested]

This is swim's first post ever after having attempted his first pseudo extraction.  Don't worry, swim has been reading Rhodiums page over and over everyday for three months and constantly UsesTFSE.  Swim decided to try the full turps cure posted by Geezmeister.  At this point swim uderstood what was meant to happen.  Here is what actually happened.

1. Crushed 12hour relief sudafed pills and soaked for 12 hours in turps then decanted cloudy liquid.
2. Boiled pill mass in nonpolar solvent (Petroleum ether) 5 times for five mins each time.
The Petroleum Ether was still cloudy by the fifth boil, swim got worried about wasting solvent so decided to dry the pill mass and perform an alcohol extraction thinking he could wash the crystals later.
5. Extracted 3 times using grade A racing fuel (95% methanol /5% acetone).
Swim realised that some gaak would come with the acetone but thought the gaak could just be expelled with pure acetone later on.
6. Evaporated racing fuel using hairdryer.
Ended up with translucent green goo with a partially formed skin/crust and very few crystals.
7.  Boiled in acetone.
This got rid of the green goo and transformed the dirty partially formed skin/crust into clean white plastic flakes.  Fuck knows what happened to the few crystals swim had.

Questions.
Are these plasic flakes povidone?
Is Petroleum Ether a suitable nonpolar solvent for this purpose?
Swim is thinking of perfoming a waterless A/B extraction instead, can Petroleum Ether be used for dissolving pseudo freebase?

Swim realises this was a complete fuck up and could imagine looking back in six months time and laughing his ass off.

If those 12 hour releif ones are the white ones that are like horse pills, good luck.  Those pills can eventually be cleaned, but in SWIMS experience it is way more trouble than it's worth.  Trust SWIM.  Yeilds on extraction were way low, post rxn workup gave horrifying gunky solids and bad emulsions.  Nothing ever can out a whole lot, so fuck em.  Stick with the red hots or something.  SWIM uses what you could call "white hots".  These only contain antihistamine, and two other binders.  That all, just two binders, being of magnesium stearate (SP?), and microcrystalline cellulose.  No PEG, or povidione, or even waxes!

(deleted/nevermind) Woops.(sorry 'bout that)

How do you find out what binders an waxes are in those, if you go by the ingredients listed underneath pseudophedrine i only got one binder wooo hoooo lol

[amalgum]

Every other box of pills on the shelf has a myriad of inactives, and they all list whether or not things like PEG, povidone, and waxes are present.  These were the only ones that were like this.  SWIM thinks the main deterrent (or what is supposed to be) is the antihistamine, which is cake to remove anyway.  All extracts thereof came out clean.

What about this petroleum ether business?  Is this solvent so nonpolar that some things won't dissolve in it,(ie. gaak or pseudo/meth freebase) or is this utter bullshit.

1. Crushed 12hour relief sudafed pills and soaked for 12 hours in turps then decanted cloudy liquid.

I hope this was mineral turps, aka odorless mineral spirits.  Not the very STINKY GUM turps which is useless.

2. Boiled pill mass in nonpolar solvent (Petroleum ether) 5 times for five mins each time.
The Petroleum Ether was still cloudy by the fifth boil, swim got worried about wasting solvent so decided to dry the pill mass and perform an alcohol extraction thinking he could wash the crystals later.

Probably fine, but this is doing the same thing as mineral turps, aka odorless mineral spirits aka odorless charcoal lighter fluid(usually).

5. Extracted 3 times using grade A racing fuel (95% methanol /5% acetone).
Swim realised that some gaak would come with the acetone but thought the gaak could just be expelled with pure acetone later on.

BAD BAD BAD
Wash with acetone first.  Its better to wask GAK out of ground up pills.  Don't wait to wash until after alcohol extraction, this will lower your yeilds and result in dirtier suzy.

You also need to wash with an aromatic solvent too, xylene.  Do this before the acetone washes.

Also, methanol is not the preferred extraction solvent for gakked pills, dry isopropyl alcohol is better.


What about this petroleum ether business?  Is this solvent so nonpolar that some things won't dissolve in it,(ie. gaak or pseudo/meth freebase) or is this utter bullshit.

In general that is sort of true.  It won't wash out all gakks.  You need additional xylene washes for that.

Good info foxy2. Could kerosene be a substitute for xylene as an aromatic? The kero available contains 98% distillate of liquid hydrocarbons under 300°C / 2% aromatic hydrocarbons. Or would kero be more of a substitute for mineral turpentine which contains more than 98% distillate of liquid hydrocarbons under 300°C / less than 0.5% benzene?
Xylene and toluene are hard to obtain.

Not good as an aromatic.  Plus its very dirty, I doubt you will ever get rid of the Kerosene smell completely. 

Xylene and toluene are hard to obtain.

You sure?
If that is true I'll bet you can get a high aromatics paint thinner or laquer thinner of some sort.  Read the labels of everything at the hardware, look up the msds of products if necessary.

SWIC bought a bottle of "mineral turpentine" today, which contains "100% liquid hydrocarbons". Is this useless for the full turps cure or what? If so, what other sort of "turps" should bee purchased?

Hes thinking of full turps-ing his aussie 120mg 12hr pills, which apparently come out easily in a turps cure.
