I notice all the repetition of of where do I get Y OTC, cant get it OTC how can I make Y form X, cant get X, how do I make X from Z, etc, posts. Perhaps we should make a flowchart of all the commonly needed reactants and general chems, showing the "food chain" of reagent/precurs synthesis, not just for those who live on the moon or actually like medieval chemistry, but to give a general overview so one could get a picture of how far back they would theoretically need or be able to go to acquire the necessary materials for a given rxn. Would also illustrate the futility of the laws which oppress us.
No one should need to make EVERYTHING from animals, vegetables and minerals(literally), but it would be nice to see that it IS possible, and to give a quick ref if one suddenly gets cut off from their source of something.
i.e.: MeNh3--hexamine--formaldehyde--hoofs
With branches for the HCl from H2 and Cl from H20 and NaCl sol'n electrolysis...etc
