Default ? on acetone

Is it possible to loose pseudo in acetone? I mean, a lot of pseudo? And why would after cleaning, the methyl look so very cloudy?

hmm, need a bit more information,,,,if you cleaned the psuedo with acetone before the A/B then sometimes because the psuedo hasnt uncleaved from the additives in the pill, these additives drag the psuedo into the acetone,,,often this is caused by the pills not being ground to fine dust or an incorrect pill cleaning regimen another possible reason for loss is you have not dried your acetone and stored it in the freezer for a number of hours before use,,,,,if you cleaned it after the A/B, then psuedo ephedrine freebase is soluble in acetone-----you say your meth is very cloudy,,,usually this is caused by impurities in the meth not being removed by cleaning,,but if your smoking it then its usually obvious as it taste is very unattractive---try cleaning it with some DRY COLD acetone

When you say methyl, I assume you are referring to methyl alcohol. Like kirby says, water is the problem when acetone is being dissolved by your "dry" acetone. Pseudo hcl is soluble in acetone at the rate of 1mg/liter. This is pretty darn insignificant. You'll spill more than that. I did not know that pseudo freebase was soluble in acetone. I thought I had heard that someone insisted on rinsing their pseudo one more time immediately prior to the reaction. I also thought that this same thing was brought up by someone else who adopted the practice stating that it worked well for either hcl or freebase. I could be wrong though. Can anyone confirm this?

Oh yeah, if it is methyl alcohol you are referring to, then your pseudo is just not clean yet.

Hey kirby--

What is it with the fucking punks today? Constantly trying to shitcan me. Sometimes I wonder why I even come here, then I think "I'm here BECAUSE of the little punks." There are a few here who actually get satisfaction when someone "succeeds" in their endeavors. The punks don't really care, they come here to laugh at oversimplified answers to elementary questions and argue.

Anyway...........

When you said tryp said so, I had to go and confirm with another trusted source. (you know. People make mistakes, typos and such)

So, true it is. When using acetone to do a final cleanup on freebase pseudo, you dissolve it in naptha or acetone, then put it in the freezer to precipitate the crystals. I really want to find the post that speaks of what my memory distorted to make sure it doesn't happen again.

It really is good to have you here, kirby. There used to be more of them than there were of us, and I'm always an easy sucker for a fight.

Why not remove the psuedo(chiral centre?)

to gain Ephedrine H-cl? What alcohol or beta-plex kind of alcohol would remove this chirality to gain Ephedrine H-cl?

OR is psuedo not removable by means of alcohols,ketones,acetones like ethyl acetone?

Can you not get some pretty nice crystals formations from this removal of chirality.

Why are you insisting that everybody uses psuedo?

its unclear who your actually asking froggy,,,nor can i answer the majority of your questions,,nor do i see where anyone is insisting on the use of psuedo,,but i can say that psuedo is more commonly used as it is the easiest to acquire
