Melting Point of pure heroin

[RangerXLT8]

So SWIM has a connect for H, that well is unlike any H SWIM has come across. Living 20 minutes from camden, NO DOPE SWIM has ever scored has come close to this. SWIM is curious to see how pure this is and am willing to melt a a bump or so. At what temperature does pure heroin melt?

Pure H doesn't need cooking.It will dissolve in water.

If you really wanna cook it you can,but why bother?


Oh and pleased you've got something good.........Take care and enjoy.

Well see we don't know if it is pure. IT has to be > 90%. It looks like the stuff when the DEA cracks a brick open.

[nick]

If it's over 90% it IS pure........just be careful.

Oh and PLEASE don't waste it trying to find out how "pure" it is.

Just enjoy and TAKE CARE.

Nick: Ever see that movie blow with johnny depp? They cook the coke to see its melting point.

OP: the problem with that is that there are cutting agents that could melt well above or below the melting point of dope, so you really have no way of testing it via that method.

Be careful :)

I've seen the movie,which is fine morlity tale.I was just pointing out that if I had some great dope,I wouldn't waste any trying to figure out how pure it was..........unless,like Mr Jung in Blow,you have multiple kilos.

and if you do have multiple kilos....... the parties at your place.

[southernbelle]

I thought we were having the party at your place, Nick.

Sure party at my place........bring your own dope and I'll provide all the sausage rolls you guys can eat.

The melting point of pure H is 229 - 233 deg. celcius.

If you have one pack it into a glass pipett and rubber band it
to a lab thermometer. A pipett dosent use any more than a 1/4
of a bump. Nice Score !!:D:D:D

Oh I forgot, Check out this web site www.unodc.org (http://www.unodc.org) .
It tells you how different cuts and percent of cut will effect the melting point.

That's an interesting website, but if you'e looking at the same report I am, it's from 1958!!!! Sounds just like the government to have the oldest information possible.

Several sites such as OSHA are saying pure heroin melts at 173 degrees celsius or 343 degress farenheit. That sounds more accurate to me.

Well now, that's pretty weird... So what if the info is old? The damn melting point isn't about to change - I guarantee that pure H melted at the same temperature in the 50s as it does today. Shouldn't be to hard to find out the real numbers. And no, you don't need much of a sample to test the MP, not if you have the right equipment. I remember back in the coke era they used to make a piece of paraphernalia called a hotbox. This was a gadget designed specifically to test MPs of street drugs. Taking a MP with a hotbox-like device is about the best way to determine a street sample's purity, to do any better you'd have to have access to a full modern testing lab.

That said, I know some people who can discern purity to an uncanny accuracy just by doing a little of the substance in question... In fact, if you send me some samps I'll see that you get a full report. ;)

[RangerXLT8]

HEy thanks for the info everyone. I have a thermometer capable of measuring up to 2000F so I will have to convert into C...

Another note: a day after SWIM sniffed, his nose was like burnt on the inside, and on the outside(where the tip of the straw touched), and by burnt I meant a scab formed.... I have heard this is from acid used to manufacture illicit heroin..

[pharmboy]

Shit Ranger ! Get some PH papers. If it comes out acid add baking soda if it
comes out alkili add vitiman C. I still stand by the melting point of 229-233C

hahahahahaha YOU WISH. lol

But seriously SWIM has done some dope in his day, all kinds from Camden NJ...And NOTHING compares.

I know the melting point of heroin isn't going to change. After reading the article I wasn't convinced they were working with PURE heroin. Here's the copy directly from OSHA'S website.

Can anyone settle this debate? :p

I pulled this out of the United Nations web site from the 50s.











Hey Z-Man could you post instructions on how to build a Hotbox? That would be cool.

Well, if I remember correctly the device was basically a tiny hot plate with an attached thermometer. You crushed the sample and sandwiched it under glass in a slide, placed the slide on the hot plate, and then you watched to see when the sample started to melt, keeping track of the exact temperature when the sample both starts to melt and also when it's completely melted. You needed to know the MP of all the potential cuts to make sense of the result. I'm not any kind of a chemist, and I don't remember the exact details... But I bet there's plenty of instructions on the web as to how you would build a basic melting point apparatus. Hell, I think we had to make one in junior high lab class, it's not all that complicated. You can probably get everything you need from an educational lab supply company.

Maybe someone who's more knowledgeable than me can post a better description of exactly what you would need to build a home-made melting point apparatus. Also, I'm assuming that you can no longer just go out and buy a hotbox, but maybe you still can. They used to cost about $100 or so.

[RangerXLT8]

So PURE heroin is oderless..... So if it stinks, it's cut.

WAIT: How do they know it's oderless, have they ever taken a bump?

[pharmboy]

Most Heroin smells like vinager because the chemists dont take the time
or the money to wash all the acetic acid out of it.

The melting point of heroin HCl is 229-233 while the melting point of heroin (base) is around 170. Hope this helps....

[robojunkie]

From Merck: Diacetylmorphine (base) mp=173 C, diacetylmorphine HCl monohydrate (common street form) mp=243-244 C. And pure H (by pure I mean >99%) is white and does not burn whether shot or sniffed. And it should not smell like vinegar if pure and clean. This is a sign of a half assed work up or the H hydrolyzing with time to the 6-MAM or even morphine itself.

If you do have a decent thermometer and any type of thin glass capillary tube you can get a good mp using less than 3 or 4 milligrams. Worth the shit if you are really curious, in fact less material is better for an accurate mp. Just remember its only qualitative though. If it contains soluble impurities even a few percent will depress and broaden the mp. One thing that virtually never happens though is an impurity (in small amount) increase mp. So if you find mp=275 C or some shit, you be lookin' at some synthetic who knows what. Just use the thermometer/capillary method already mentioned and an oil bath to heat it in. If you know what you're doing you could try to recrystallize it from ethanol/hexanes (as in lighter fluid). And that would be cold recrystallization. The HCl salt is soluble in 11 parts ethanol and essentially insoluble in hexanes. So dissolving in ethanol first doesn't dissolve everything in a reasonable amount/time, the shit left is impurity. Conversely, washing with hexanes would remove any oily impurities.

[RangerXLT8]

Well SWIM got his hands on some more of this. I am not going to do a mp test right now because I do not have the means. The shit does slightly smell like vinegar.

The next thing that happened was new to me. The diesel is off white, and looks kind of crystalline. When preparing a shot in a spoon, the solution is practically clear, every other time SWIM cooked a shot of dope the water was brownnnn. I hear this in itself is a sign of good diesel...

Peaceout,
Ranger

Pure H is pure white and crystaline.It dissolves in cold water and doesn't smell of vinegar.
