Ok, I sped the drying process up in the oven, fan oven, set below 100 deg C. (looked like about 80).
I am left with 168mg of a dirty yellow/white residue - slightly waxy in texture.
If this was pure 2C-B then that would mean my yield is 16.8mg per tablet (advertised at 20mg) which would be pretty decent yield of 84%.
I have no doubt that this is not pure 2C-B though so my yield is definitely lower but a fun exercise non-the-less.
As it is slightly waxy, my desire to insufflate this is not going to be all that good, so I will dissolve all 168mg into 5ml of 0.9% saline and place into a nasal spray. As it dissolves with no problem this should be an easy administration method.
My nasal pumps give me 30 actuation's per 5ml, so at 168mg, this would give me 5.6mg of this 2C-B residue. 2 pumps should be a very decent dosage.
Second image is after adding the 5ml 0.9% saline - thw water has gone a slightly off white milky colour and there is sediment floating in it. This is start contrast to the clear water that went into the evaporating stage.
So, either the heat was too intense and I cooked something in the oven, or the evap/drying process has mucked with some of the adulterants/binders that were soluble in water and they have now come out or something in this didn't like saline solution. Granted, the clear water was over 100ml and this saline is only 5ml, but even during drying the water didn't change colour, so something definitely up.
I may sacrifice another 10 pills to trying this again and changing a few things.
1. teflon tray for drying
2. dissolve the tablets after crushing and allow to settle before filtering, stopping before sediment gets to filter.
3. Each successive wash would be allowed to settle.
4. use smaller amounts of water (30ml per wash not 50ml)
5. Allow for a slower natural evaporation (until I can get my hands on something to speed that up...)
Anyway - that is today's exercise in filtration and evaporation
