| titleOfInvention | Stabilization of aqueous solution of calcium nitrite |
| abstract | PURPOSE: To easily stabilize an aqueous solution of calcium nitrite in high efficiency by absorbing NO and NO 2 in an aqueous slurry of slaked lime, separating the remaining slaked lime by filtration and adding nitric acid to the aqueous solution to adjust the content of calcium hydroxide within a specific range. n CONSTITUTION: A gas containing nitrogen monoxide and nitrogen dioxide at an NO/NO 2 molar ratio of ≥1 is absorbed in an aqueous slurry of slaked lime and the remaining suspended slaked lime is removed from the slurry by filtration. The obtained aqueous solution of calcium nitrite having a concentration of 20W40wt.% can be stabilized by the following process. The amount of calcium hydroxide in the aqueous solution is adjusted to 0.08W0.02wt.% by the addition of nitric acid to the aqueous solution. The nitric acid used in the above process is preferably an aqueous solution having a concentration of about 10W55wt.%. The addition of the nitric acid is preferably carried out while stirring the aqueous solution of calcium nitrite. n COPYRIGHT: (C)1989,JPO&Japio |
