I have what is maybe a stupid idea but in 1930 the health people outlawed acetyloxymorphone because of its increased potency linking it to heroin. So why couldnt you try using distilled white vinegar added to a little water to dissolve the pill. Does this effectively create acetylbuprenorphone?
Not really.
First of all: It is buprenorphine, not buprenorphone.
Anyway: You know how Mexican black tar heroin differs from "proper" heroin? Basically, "real" heroin (i.e. 3,6-diacetylmorphine, which has two acetyl groups) is made using a substance called acetic anhydride, which is *really* effective at attaching those acetyl groups. Mexican BTH, on the other hand, is made by boiling morphine with glacial (i.e. pure) acetic acid, yet it still mostly contains 6-monoacetylmorphine (as the 6-position is more readily acetylated), whereas the only position to acetylate in buprenorphine would be the 3-position.
As sekio said, white vinegar is only 5% acetic acid, and since you further diluted it with water, and you need to acetylate your bupe at the 3-position, there is basically no way that all but the tiniest trace amounts of acetylbuprenorphine were formed. *If* you were to create acetylbuprenorphine, the best you could hope for would be higher oral/sublingual bioavailability; I wouldn't expect it to make any difference when injected (while both a 3- and a 6-acetyl increase bioavailability, only the 3-acetyl-group also prevents the molecule from binding to the receptor before it is cleaved off).
Also, food for thought: IF successful, wouldn't you also be acetylating the naloxone, thus creating acetylnaloxone? One of the reasons naloxone works as an abuse deterrent in pills is because its oral bioavailability is so much lower than that of most opioids (whereas IV bioavailability for naloxone would be 100%, so you'd suffer precipitated withdrawal when injecting it); however, suboxone has been criticized for not containing enough naloxone to do that: Bupe itself has a pretty low oral bioavailability, and coupled with its strong receptor affinity that means that the relative increase in BA of naloxone over bupe isn't great enough for the naloxone to displace most of the bupe when injected; at best it blunts the initial rush.
Presumably, 3-acetylnaloxone would be a more effective pro-drug for naloxone, so your acetylated suboxone mix could actually be *inferior* (atleast orally/sublingually) to the original.
tl,dr:
No, you're not going to be able to create acetylbupe like that, and even if you did, it might actually suck because you'd also have acetyl-naloxone in it.
Edit: Also, the one banned in 1930 was
acetylmorphone (i.e. 3-acetyl-
hydromorphone, not
acetyloxymorphone).
