Well, since people have been talking about turning Morphine into Heroin with acetic anhydride I thought I would post about something similar that may interest the chemically inclined. This post may be useless but it seemed interesting to me and it could possibly help out some people who want to experiment with a substance that is an opiate and more potent than Heroin.
I was searching Wikipedia looking at different opiates and I came upon this one called Dipropanoylmorphine. Now you are probably asking yourself, "What the fuck is that?" and I will tell you what it is. This is from Wikipedia and not in my words but it explains what this substance is.
is the 3,6-dipropanoyl ester of morphine, CAS number 10589-79-4. It was developed in the 1970s as an analgesic.  It is rarely used in some countries for the relief of strong pain such as that caused by terminal cancer, as an alternative to diamorphine (heroin).
So.....we have this substance that is more potent than Morphine, and is an alternative to Diamorphine and more potent than that also. It is rarely used and supposedly has effects similar to or better than Diamorphine (Heroin).
So, when you create Heroin out of Morphine you have to get your hands on Acetic Anhydride, this is not really easy, as it's a watched chemical because it's used to make Heroin out of Morphine. So it's not really realistic to order some online, as you will probably end up with DEA agents breaking down your door.
So to make this opiate that is MORE POTENT THAN HEROIN! You need to do the same thing as what you do to make Heroin out of Morphine. Now you will probably say, well how the fuck can I do that if acetic anhydride is a restricted chemical, and my answer to you is...... YOU DON'T NEED A RESTRICTED CHEMICAL TO MAKE THIS OPIATE FROM MORPHINE! You need a chemical that ISN'T WATCHED. The name of this lovely chemical is PROPANOIC ANHYDRIDE.
So, get yourself some of this propanoic anhydride and get your Morphine and react the Morphine with the propanoic anhydride and BOOM SHAKALAKA! You have DIPROPANOYLMORPHINE.
So now you have a relatively easy way to make a drug that is said to be stronger than Morphine and Heroin.
I hope you enjoyed my writing and that this opens some doors for some people. I'm not telling you to go out and do this. I have not tried the product of this synthesis and I doubt many other people have. This is a rare drug and I don't know what effects it has on liver or kidneys or anything but from the literature I read, it's supposedly safe for human use and stronger than Heroin. And the potential for a better buzz is there. Even if the buzz doesn't beat Heroin, i'm sure it will beat a Morphine buzz. This DIPROPANOYLMORPHINE is also highly lipophilic, even more than Heroin.
Disclaimer: I am not responsible for any deaths or injuries/illnesses caused by someone making this drug. I am simply writing this to broaden peoples knowledge on other opiates and for my own personal amusement. I don't want you to try this, and I'm not responsible if you do try this. Nor is this website, Opiophile.org. If you do it, you are responsible. I do not approve of it and I don't think it's a good idea to make this drug. Be smart and don't do anything stupid. This is strictly for the chemically inclined who know their shit and who won't blow themselves up. I am not RESPONSIBLE for YOU or your friends dying or getting hurt so don't fucking blame me or opiophile.org. Peace
