You can separate out the NMT derivative by chucking in some dry ice. It will form a self-carbamate which remains insoluble in warm naphtha.
Search the forum for the NMT/dry ice thread.
“There is a way of manipulating matter and energy so as to produce what modern scientists call 'a field of force'. The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
― Jacques Bergier, quoting Fulcanelli
