I did some quick searches thinking I'd find we produce vastly more iron than chlorine, and we surprised to learn that we only use sixteen times more iron.
Being so reactive I imagine. If chlorine were much much cheaper we would find many more uses.
Big use-case, problem is that in case of fire lots of dioxins are produced.
Yes, and chlorine is the stuff that no one wants, so it's turned into polyvinylchloride, which isn't really useful unless with copious quantities of plasticizer.
For something nobody wants it costs several hundred dollars per ton to buy
The price of chlorine though is much lower still and it has been very stable until recently. How elastic is demand for PVC?
