Author	Topic: Difference between Ephedrine and Psudoephedrine?
Kirt NewBee	posted 12-22-1999 06:48 AM I am a beginner to the chemistry field and could someone tell me the difference between Ephedrine and Psudoephedrine? Can a person extract the E needed out of ephedrine as well as he/she can from psudoephedrine? What ingrediants need I look for that I do not want?? Someone, Please? Also, here is a dumb one, what is H2O2? ------------------ I'm out! The Captain
hypo Hive Bee	posted 12-22-1999 09:59 AM E differs from P by configuration on the carbon bearing the OH-group. Since OH group is probably what you want to remove, P is as good as E. H2O2 is hydrogen peroxide. I suggest that you do not proceed to the experimentation level until you get some chemistry intro.
Kirt NewBee	posted 12-22-1999 01:18 PM Hey Hypo, I know my questions sound dumb but I already had a dream and it was a beautiful one! The yeild could use a little improving but the dream was sweet! I just ain't to hip on all the chemcal terms! WHich would be very helpful if I were! So one can extract good e from ephedrine just as well as psudoephidrine? I was told awhile back that the ephedrine pills were not what I wanted! It was the psudo only! Anyone help me understand Y this would be true? ------------------ I'm out! The Captain
Android Hive Bee	posted 12-23-1999 04:47 AM The only difference that's important to me between the two, is psuedo's readily available where I live. That, and I don't care for the high the Ephedrine reduced meth gives me. Leans more towards the adrenaline and not enough euphoria. Chemically, they're mirror images of each other. Kinda like a newbee and a gnat. ------------------ "ARROGANT & CYNICAL" (Ticklish,too!)
mrr pyrex Hive Bee	posted 12-23-1999 05:32 AM Good one Android!! Gnat and Newbee....Rollin on the floor, pissin uncontrollably :-) Pyrex out of piss
hypo Hive Bee	posted 12-24-1999 08:02 AM E and P are NOT mirror images, damnit! They are epimers, it means they differ in only one stereocenter.
Xtract Hive Bee	posted 12-24-1999 08:26 AM Droid I respect youre opinion are you saying there is a differance in highs? Ive thought for a long time they maybeee way differant. You noticed they took Ephedrine off the market? Why???? Psudo is Psudo i.e. not th.... same not mirror images, Phuck I hate when I cant seee what Ive typed. Do any of you know what they really look like? Xmenot
Android Hive Bee	posted 12-24-1999 03:32 PM I see no argument with the newbee/gnat theory, wypo. Not certain of you facts, maybe? Xgnat. Brown nosing will only attract flies. What I'm saying is of no importance. Ask anyone! ------------------ "ARROGANT & CYNICAL" (Ticklish,too!)
dextram Hive Bee	posted 12-24-1999 03:50 PM That sounds like pretty reputable talk the real question would of course be though will in fact due to the difference in the chirality of the epicentrical OH group will this in fact cause slightly different reactions such that possibly during workup maybe pseudo goes through transition upon the c2 spot and that ephedrine would go through trabsition in the c5 spot irregardless of these activities how many might agree that this in fact is a cyclization event in the benzene ring??? I have some reliable pictures of pseudo and the structure problem is the citation is not so specific in the dfination of the diagrams it appears pseudo forms a bit of a different ester, that the ster is in fact not a benzene ring strugture I dont know enough about different esters to really explain presently but these esters concerned might possibly be esters from that umm stuff a while back umm something explosive it is um found in asprin apparently can be got from asprin, used to make colored crystals to check for MDMA apparently is a process for eluting chemical physical charesterics um posed within the last month I belive, I think polymerization is a real posibility with and strange products whith these methods including many possible amphetamine like substances not all of course should be defined as meth.

Sky Hive Bee	posted 01-11-2000 10:22 PM I've got DL psudoephadrine from DR. that made much better meth than the OTC shit you can get I know its been Discussed in here I think there are different Isomers in both psudo and Ephadrine. and the shit you get OTC is not going too be the good stuff.
Methamphibian man Hive Bee	posted 01-12-2000 03:04 AM Just an observation: sudafed 12 hour is a pill that has ONLY psudeoephedrine in it with a thin outside coating that is easily scraped and peeled or washed off. it is the cheapest price too!
Yman Hive Bee	posted 01-12-2000 03:50 AM Hey wow,...Android did not really flame us ! and in his own way really did answer our questions. Thanks Wo.... An. Did you see the way Worlock trashed that guy the other day? POor NewBee> Seeyaa.
Xaja Hive Bee	posted 01-12-2000 03:50 AM Yeah but it's got binder shit in it that can make life very difficult. Although you can dissolve it in cold water, filter real quick with a buckner, then heat it. Whole lotta jelly shit comes out. But now the bitch: it won't filter anymore. Jelly shit clogs filters. But for small quantities, heat it in an enamel dish and the jelly shit seems to stick to the enamel. But it really is a bitch. Avoid them if you can.
Snotbrain Hive Bee	posted 01-12-2000 02:49 PM Anhydrous, please explain further your reflux routine. ?? You reflux what, how, to get what?? H2O2 is what it takes to make you blonder, kirt!
Snotbrain Hive Bee	posted 01-12-2000 03:44 PM I wonder if the reflux accomplishes the same thing as the heating and pressurization referred to in the dwarfer "nickel" thread? (By readyeddie) do you use acid also: or just water?? snodder
Acme Hive Bee	posted 01-12-2000 11:51 PM This came up in the general forum 3 monthes ago posted 10-12-1999 09:03 AM -------------------------------------------------------------------------------- This will seem pathetic, but is the d- or l- isomer the desired one, and how exactly is pseudoephedrine different from ephedrine (just stereochemistry or r they consitutionally different) Also are any of these compounds at all stimulating on there own, or dangerous? (i know of an OTC medicine which is DXM and pseudo, any problems there?) Acme Member posted 10-12-1999 01:58 PM -------------------------------------------------------------------------------- Hoping you can deciper this shorthand They both have the formula C6H5CH[CH(NHCH3)CH3]OH they differ in stereochemistry eph (-) 1R,2S eph (+) 1S,2R psu (-) 1R,2R psu (+) 1S,2S Not sure which is called d- or l- . It would be a wild guess to say (+) is d im just not sure. Hopefully some wiser bee can clue us in on which is d or l and which one would be best (for your cold, of course) CHEM GUY Member posted 10-12-1999 02:00 PM -------------------------------------------------------------------------------- Slappy, where did you get that info? I'm not questioning you but I just want the reference- CHEM GUY Member posted 10-12-1999 09:15 PM -------------------------------------------------------------------------------- From Fornsic science international, 48 (1990), 123-34 "...(-) ephedrine or (+) pseudoephedrine yeilds (+) methamphetamine." From the journal of Forensic science, page 956 "...(-) ephedrine and (+) pseudoephedrine yeild d-methamphetamine" Therefore (+) methamphetamine is d-methamphetamine.
