反応手順
In 1970, Richmond et al ('641 supra) reacted phosphate rock with phosphoric acid and then with sulfuric acid. The resulting acidulate was subsequently neutralized with anhydrous ammonia to produce a 7-21-0 (N--P2O5 --K2O) grade slurrey fertilizer. In later investigations Pottgiesser et al ('162 supra) produced a 13.5-6-0 (N--P2O5K2O) grade slurry by reacting nitric acid with phosphate rock and subsequently feeding the resulting slurry into a body of preneutralized solution maintained at pH 7-10 by addition thereto of aqua ammonia.
