Methylcyclohexane is a seven-carbon saturated hydrocarbon like heptane but with one end bent round and joined onto the penultimate carbon of the chain to form a six-membered ring - hence
cyclo[ring]-
hex[six carbon]-
ane[saturated hydrocarbon]. The remaining carbon atom, the methyl group, pokes out from this ring. Toluene is also a seven-carbon hydrocarbon but it is 'aromatic' - which means it contains a ring of alternating double bonds (at least formally). It's like methylcyclohexane minus six hydrogen atoms.
Products containing stuff like toluene or xylene will not be conducive to freeze precipitation. DMT is simply too soluble in them, even at low temperatures.
βThere 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-Γ -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."
