SpwnX: And what machine would you use for that ? The Chemical Reactor ? Does it releases energy ? The Idea is to make my suggestions having recipies as well, aka content 
Chemical reactor. I think we need a better chemical reactor (aka more slots), to allow us to have reactions with more than 2 reagents and more than one product.
Methane (CH4) + chlorine (Cl2) = chloroform (CHCl3) + HCl (Hydrochloric Acid)
Chloroform + spray can = "stun spray" , gives slowness 10 for 5 minutes, blindness 5 for the same duration and poison for 10 seconds.
Hydrochloric acid (HCl) + Nitric acid (HNO3) can be used to make "aqua regia".
Aqua regia can be used to increase yield from gold and platinum ores. (Aqua regia will dissolve only gold and platinum from ores, separating them from byproducts)
Aqua regia + gold ore = "Aqua regia - Dissolved gold" + byproducts
Aqua regia + platinum ore (sheldonite) = "Aqua regia - Dissolved Platinum" + byproducts (iridium/osmium)
Aqua regia - Dissolved metal can be electrolyzed for metal (more than other process) + aqua regia (less than initial)
