If you want I could list some? I'm from New Zealand and we use it all the time making heroin over here. I was thinking of putting some up. How would I send it?

Just send it as acetic acid, say, 80%.
And fill the customs form out, no one knows the difference, if they test it there WILL be some acetic acid inside. Just let the container open for 10min!

I get this shit by the milk jug full and have already hooked up a friend on here with it. I don't want to name him but if he feels comfortable, he can come out and say something.

You don't need that. I saw a listing on ebay for acetyl chloride 250 ml. I was gonna buy it myself but i'm too lazy to make my own pure 99.9 percent H. Just dissolve some morphine base in anhydrous pyrdine in a ice bath and add the acetyl chloride dropwise. Acetic anhydride will give a mixture of products. but if you use the wright-beckett process you can produce more of the 6-MAM if that's what you're after.

Lol, about acetyl chloride, we have access to that too but we avoid it. It's carcinogenic and doesn't naturally break down into something safer to ingest on it's own. acetic anhydride -> acetic acid with hydrolysis but AC just stays in you. Btw, that part where you suggest placing morphine in pyridine doesn't sound right to me. Pyridine is what we used for removing the methyl ring from codeine. AA or AC for acetylating. Maybe I'm wrong and this is a method I'm not familiar with but this is something we do every day here. As a heroin user, it's your life.

That would be me, and it's totally legit. Smells strongly of vinegar. It's strong and corrosive though, and should be treated carefully. I'm about to do a cook with it as soon as I get more morphine tabs. The good thing is, a little bit goes a really long way, so you don't need much. You should consider chucking some up on the site methadonia

Yeah, I also agree with Methadonia about Pyridine. Pyridine is used for demethylating codeine into morphine, and then you actetylate the morphine with acetic anhydride to get diacetylmorphine/heroin.

Can you get pyridine methadonia? As you may remember, I can get a fair bit of dihydrocodeine, and I think that using pyridine on it would convert it into dihydromorphine, but I need to do more reading up.

Yeah, can definitely get it but it'll be harder than double to obtain, because these days everyone worth their salt starts with morphine instead of codeine. So demand has heavily decreased and with it, supply. But it is out there. My mates friend whom basically slept on the couch and floor would always be getting rare and useful chems through this kid. He would give or swap us bottles of chloroform, ether, pyri, dub, caustic, hcl acid whatever you wanted really. At the time I wasn't advanced enough to do the larger scale cooks I do know when I can. They were always 1-2 doses at a time. No when I get offered a full card of 100mg eslons I jump on it.

btw, this is a real annoyance to me and I'm not the type to do this (tried once for something related and sorted it myself before anyone helped) but I'm short .26 btc on something I've wanted a while now. Only poinr two six. If someone could help, I can write you a short story of your chosen theme and it goes without saying you'll get it back asap

I'm sorry you have tentative knowledge of the subject that caused your presumption. I'll be more clear. The solvent Pyridine is used to stabilize the nascent transition state in the alcoholysis reaction making it highly favorable and causing the reaction to go to completion. Forming the acetylated product heroin freebase and pyridine hcl. Which can be easily separated via their difference in hydrophobic versus hydrophilic properties in a separatory funnel. The acetic anhydride reaction leaves a mixture of products because it's a very poor reaction. I also disagree with you that acetyl chloride doesn't naturally break down. It forms acetic acid upon exposure to moisture.

Acetylchloride is easy to convert to AA, you just need some water free natriumacetate!
Put both  the acetylchloride and the natriumacetate into the freezer and prepare an icebath.
Then put 1mol of  natriumacetate VERY slowly into 1mol of acetylchloride.
Be very careful, this is a damn strong exothermic reaction!
Later add a little bit more natriumacetate to be sure that the conversion rate is really 100%.
Now you have AA with natriumchloride in it, it is ready to use but if you want, you could distill the AA.
I have done this a long time, but now even acetylchloride is banned in my country.

I NEED SOME!

Touche Janus, pyridine act as a catalyst  ;)

I have around 200g pyridine hydrochloride and A chloride. Thionyl chloride, red phosphorous, iodine, ether, chloroform also available.
Pyridine hcl is solid and few grams per package can be listed.
Liquid chemical would present a shipping problem and I am not sure how to process it.

I am a chemistry consultant.  What are you interested in AA for if you dont mind?

If you are making smack I have a very nice trick I will share with you.  Either way I have a very simple method of making acetic anhydride.

Don't make it harder than it needs to be, talk to a pro.

Have you actually worked with both substances in heroin manufacturing? I take it by your preference for outlandish and unnecessarily complex methods that you don't. I acetylate heroin like most people microwave noodles, so while my knowledge of chemistry is limited, trust me when I say I have cooked heroin using a large variety of methods and there's a reason acetic anhydride is the golden standard. Using pure morphine and another trade secret when cooking it, you'll have a more then satisfactory outcome. Street heroin is a mix of alkaloids not just diacetyl. in fact, most people who end up trying heroin without the 6-MAM, 3-MAM and other alkaloids end up preferring the street / mixed stuff because it has a better hit.

So while you may have read a few different patents and can happily rattle them off to me, they mean zilch if you've never actually set about doing them. I've been cooking heroin for years now and I can tell you, I and everyone else I know who does it will take AA over AC any day of the week. It is nasty, hcl fuming crap.

If I gave you the pepsi challenge with heroin cooked with AC and AA, you'd take the AA.

Instead of using acetic anhydride, try propanoic anhydride.  One extra carbon, makes it more fat soluble, crosses the blood brain barrier easier.  This makes smack that is knock-out active at like 20mg and lasts 12+ hours.  Heres a trade secret: use a tiny amount of sodium acetate as a catalyst to speed up this reaction.

Making both acetic anhydride and propanoic anhydride are a lot easier than it seems.

Get a pyrex and sprinkle it with 1/8" sodium bisulf*A*te, put this right up under your oven heating element set on broil.  Keep going until it bubbles and a thin white film develops on the surface.  If you see white vapor coming off you are heating it too much, although most ovens are perfect.

When this is done let it cool, break it up and blend it into fine powder, leave it in the blender.  This is sodium pyrosulfate.

Calculate an equimolar amount of calcium proprionate (for propanoic anhydride) or calcium ethanoate (aka calcium acetate) (for acetic anhydride).  Toss this in a blender with your sodium pyrosulfate and mix, then quickly pour it into a pyrex boiling flask.

Toss this in a heated sandbath with either a distillation head or a heat-safe tube coming off it.  Your anhydride will distill off easily with no side products.

Ahh good ol Dipropanoylmorphine. I'm familiar with that one Doc, though due to the extra chemicals and steps needed it's not as commonly done. I realise how silly that sounds, considering the ease of production but them's the breaks as they say.

Have you personally tried it?
I can't understand why its not the industry standard, higher bio-activity and more pleasant long lasting effect.
I just want to fly out to the middle east and tell our CIA to start using a better process, those drones will damn near buy themselves.
Title: Re: acetic anhydride
Post by: Methadonia on September 24, 2012, 07:51 am
I've tried it once but never made it myself. It was nice but really didn't feel a whole lot different to one of the many many diamorph/6mam/3mam variations I've had  It'll never be as popular as regular diamorph sadly because the routes of diversion for the AA are well established here and there and everywhere. People generally fear new things.

For the record, if you've ever seen heroin made using acetyl chloride you'd not want to stick it in your arm. When you add it to the morph, it fizzes and bubbles and fumes rise off it.

Good point, iv read the most common human drive is not survival, or even sex.  Its the drive to do whatever is familiar.

Have you seen buffalo soldiers? Anytime I think of large scale smack synthing I think about the scene with all those military guys stuffing meat in their mouths cooking giant smack batches.

I don't even know why im posting this, im a little twisted and am intrigued with your experiences with opiate chemistry.
Title: Re: acetic anhydride
Post by: Methadonia on September 24, 2012, 09:24 am
hehe I can tell you it's nothing like that. It's more like a smelly guys house, shitty cars on the driveway / yard being worked on. Trash and crap everywhere. Anxious junkies standing around watching you cook, anxious to get their taste. Heroin really is simple to make from morphine. It used to be done from codeine since it was otc, before there was real widespread enough availability of morphine tablets to be able to do grams of it. Now most of the skill has gone out of it. Still, I order heroin from here occasionally, just because you get a different ratio blend of the alkaloids.

Easy there, I wasn't trying to hurt your street cred front o' yo homeboys. I'm just telling you the better way to do it since the acetic anhydride reaction may get you 80 percent yields of acetylated alkaloids alot of them useless like pseudomorphine, 3-MAM while mine will get yields in the upward 90s and no degradation. But Hey, all the tar and degradation products will help get the good ol' H up to your brain easier. Far be it from me to judge what you think is getting you high. I guess it's like the Doc says about familiarity not survival that motivates people.

Because, amounts over one gram of propanoic anhydride are a class A felony since it's used in the prep of fentanyl while you can have alot more acetic anhydride. That's just in america. In the middle east, it's more like the death penalty.
