For dmt, I always go the path of STB + mini-A/B (with
back-salting/titration) + re-x. Initial pulls are with toluene.
You can try to hit "Search" and find my posts containing word "heptane". It can find some of my posts where is described what to do (like
this one)
In fact you only need to understand
back-salting/titration, it is quite simple procedure.
I wouldn't use evaporation for the solvent (toluene). It is much better to use freeze-precip with naphtha or back-salting for toluene/xylene.
Acceptance of the fact that our reality is not real doesn't in fact mean it is not real. It just leads to better understanding what real means.
