Concentrated Nitric Acid Market
Items used in coal and metal mining are of particular importance to the explosives business, which paves way for rapid development of the global concentrated nitric acid market in the near future. Nitroglycerine, trinitrotoluene, toluene diisocyanate, nitrobenzene, adipic acid, and ammonium nitrate are all made with concentrated nitric acid.
