Nitric acid at room temperature can react with all metals except gold, platinum and titanium to produce the corresponding nitrates. Both concentrated and dilute nitric acid can react with copper at room temperature in a way that hydrochloric acid and sulfuric acid cannot. Nitric acid manufacturer shares with you some basic chemical properties about sulfuric acid and how it is manufactured.
Also nitric acid is a planar molecule with a sp2 hybridized central atom N atom. The molecule is planar because the hydrogen atom on the hydroxyl group forms a hydrogen bond with another oxygen atom, and all three bonds of N are of different lengths. one of the p-orbitals of the N atom perpendicular to the molecular plane is full, and it is conjugated to the p-orbitals of the two oxygen atoms not attached to H, forming large π-bonds. Intramolecular hydrogen bonding is also responsible for the lower boiling point of nitric acid.
The structure of nitric acid with one hydrogen atom removed is nitrate, which generally carries a negative charge (nitrate ion). Nitrate has a symmetrical planar equilateral triangular structure with four atoms forming a large π-bond and one extra electron in an off-domain π-bond.
Nitric acid, as the highest valence (+5) hydride of nitrogen, is very acidic and aqueous solutions of nitric acid are generally considered to be completely ionized. Nitric acid can undergo esterification reactions with alcohols, as in the preparation of nitroglycerine. Only when mixed with concentrated sulfuric acid, nitric acid can produce large amounts of NO2+, which is the essence of the nitration reaction that can be carried out.
The aqueous solution of nitric acid is highly oxidizing and corrosive regardless of its concentration, and the more concentrated the solution, the stronger its oxidizing properties. Nitric acid decomposes into water, NO2 and O2 under light conditions, so it must be stored in brown bottles and kept in a cool place. Nitric acid can dissolve many kinds of metals (silver can be dissolved), producing salt, water and nitrogen oxides.
There are two main methods of producing nitric acid by nitric acid manufacturers
The air passes through the water washing tower and filter in turn through the blower to remove mechanical impurities and dust, enters the mixer to mix with the filtered ammonia, and then enters the oxidation furnace to react to produce high temperature nitrogen oxide process gas. The process gas is cooled down to 40℃ by boiler and cooler, pressurized to 0.35Mpa by compressor, and lowered to 40℃ by heat exchange to enter the bottom of absorption tower and react with the water added at the top of the tower, and the dilute acid is discharged from the bottom of the tower into the bleaching tower and sent to the acid tank after bleaching, and the tail gas from the top of the absorption tower enters the alkali absorption tower. The exhaust gas is discharged into the atmosphere after alkali absorption.
