Swim previously posted a table comparing in detail the ingredients of OC's with the ingredients of OP's, along with a suggestion for a full extraction procedure that does not use dangerous solvents like acetone or MEK
Because this site does not support either the TABLE bbcode or HTML, swim is including a link to that post:

Here is the post without the table:
If the chimp swim's friend met on the way to the Bronx Zoo was correct, the reason that the microwave/freezer process works well for some people but not as well for others may have to do with how different microwave ovens act upon the combination of BHT and oxidizable components of the OP. Getting rid of the BHT may make the process more deterministic. A workable procedure might look like:
- Mix powdered pills into a volatile liquid fat, and mix thoroughly.
- Let the solids separate out.
- Drain the fat, which should now contain the dissolved BHT (drain just the fat, not the remaining solids)
- Let any volatile fat remaining in the solids evaporate (maybe hurrying it along with heat)
- Oxidize, either using heat or with hydrogen peroxide. If the latter, let it evaporate.
Some people may consider themselves done at this point. Others may continue as described here:
The remaining powder should (thoretically) no longer gel up, and all of the oxy should now easily dissolve in water. The result of evaporating such a solution after solids are removed from it may be significantly smaller than with OC's, as there is no longer any lactose to be dissolved together with the oxy, so it may be even more important than before to use an "open-air siphon" rather than filters to separate out the solids from such a solution.
- Mix remaining solids with hot water, stirring thoroughly. (Don't worry about the heat. The melting point of oxycodone is much higher than water's boiling point.) Cool to a bit above freezing, and either remove the liquid from the solids with an open-air siphon (preferred), or pour what's left through a filter
Neither Swim nor Swim's friend have any OP's to try this out with (we just don't want to see people turning to heroin), so please use this info to brainstorm and/or report results of experimenting with it.

Update: A google search shows that BHT dissolves in Limonene, the main component of both lemon oil and orange oil, and Amazon sells quarts of "Erath Earth" brand orange oil for a very reasonable price. They also have "aromatherapy" lemon and orange oils for not-so-reasonable prices.
Orange oil is sold as both a cleaning solvent and as a "non-toxic insecticide". In pure form, it is a skin irritant, so it should probably be handled with gloves.
Note: Stated briefly, an "open air siphon" is basically a string with good capillary action that permits liquids to travel upward from one container and then downward into another container without also transporting any solids that may have been loosely suspended in the source container - the five inch long central portion of an Oral-B "superfloss" string works great for this -- it's more efficient than using a filter, there is less waste than with a filter, and unlike a filter it doesn't get clogged, and in fact can be re-used many times!
