You only need one acid pull on the toluene, if the pH after the pull is still 3 to max 5 you are set. You can do a second one for peace of mind but not really necessary I think.
Evaporating such acid water is preferred over evaporating pure toluene.
Your acid water will smell like toluene but now it is traces of toluene only.
Evap volume down til oily, add new plain water + mix, evap down, add maybe some ethanol if you have, evap down, ..., till there is no more toluene smell.
If muriatic acid is used then also the excess acid will evaporate in the process and in the end pH will normalize after a few evaps to 5 or so, thus safe.
This process is used on chaliponga leaves with good result, and yes it stays a bit sticky and will hold some none active components but you do have full spectrum actives.
Then you can indeed base with sodcarb and pull with ethanol as you say. Expect no dry result, chances are you will get something sticky but potent. It will be full spectrum!
If you pulled with naphtha instead of ethanol you get the nn-dmt, but be careful with heat as very warm naphtha does take dmt oxide in it!
Then pulling with ethanol for the rest, prolly dmt oxide, just as potent.
Fresh wood will be a less oily result than old wood. I've seen wood with near none dmt oxide, and old wood with 50% nn-dmt and 50 % dmt oxide (long time open air stored somewhere?). It was reduce-able with zinc so really pointing to dmt oxide.
...So is burnt's suggestion to use a stronger solvent like toluene and cleaning it up with naphtha outdated or is it just too difficult and messy?
Now if you have 1.6 to 2% readily with naphtha pulls alone on the wood, I recon there's no use to hunt for the oxides and consider toluene pulls as unnecessary. But if your naphtha pulls on the wood give like 1% yield, chances are you have old wood with just as much dmt oxide waiting to be ignored or pulled with toluene.
1- the mini ab step is incorporating a cleaning up step;
2- the toluene pulls very powerful on the wood and needs no warmth at all, room temp is OK.
