Default Lucky D, Chemhead, Another idea on extracting that might me easier!

Sorry Lucky for the long time to respond. I was busy in summer school and work. I would like the full zip of chemhead files and forum if you have them if not...Do you have them acidmelt? Also, can anyone give some research info on long wet reflux just need to compare and contrast. Oh, one more thing, I don't know how well this will work, but when extracting P-fed, from pills, it might be a good idea to get a flask, and but 1 half volume of N.P. solvent, and 1 half water. Kinda like a a/b reaction. Since amine's are polor because of the hydrogen bonding that occurs, the p-fed should be force to the bottom, leaving the crap in the N.P. layer. If you are just using a "nol" methnol, or isopropyl, then you either get junk are not 100% p-fed. So by having a polor layer and a nonpolor layer, you give the shit somewhere to go. Later

ADD kid

P.S. I just realize that water would be no good to use, because peg will mix with water without thinking twice. The key is this... Peg will not mix well with aliphatic compounds, which is anything with carbon that is nonpolar and without a ring. Ex. methanol. The idea is to make two layers or two parts of organic material. One that is aromatic, (organic compound). And a organic compound that does not contain rings. The Peg is dissolve into the aromatic part and the P-fed will flow into the aliphatic part. But the trick is this.... You need to try to get the most polor aliphatic compound. This aliphatic compound should not contain any water. Ex. Methanol would better than isopropyl because the Oxygen can deal with one R-group, anymore than that and the compound becomes more and more nonpolor. So one might use coal fuel for the aromatic part, since it contains many aromatic compounds. Some say only use naphtha or xylene. But it really doesn't matter. However you might want to have a bigger volume of aromatic layer compare to the methanol. If you only have a necessary amount of methanol, the methanol will chose the p-fed over the peg. Overwise to much methanol, and then the methanol invites the peg to the party.

Add kid ....disregard coal fuel, xylene would be better.

P.P.S. By the way I think the orange shit is just when a ph is lowered to much or raised real high. It is a reaction between the peg, and the base, or acid. I think. In previous reactions, I would think that all of your reactions had the stuff in it. But you got lucky and the reaction never happend. The product from the rxn of the peg, and meth, might produce something else, but if the peg does not react, then it doesn't fuck up the meth., that is what is seems like to me. Since some say they see it and some say they don't.

Add kid ....acidmelt please give you input on this.

Yeah Luckky, Switired would also like some info on the Long wet reflux. He's done some reading and looking but has come up with nothing....Thank You
