What is nitric oxide? What are the physical properties of nitric oxide?

It is an oxide of nitrogen, in which nitrogen is +2 valence, which can be prepared by oxidizing ammonia with oxygen, and needs to be catalyzed by PT, oxygen should be a little less, otherwise oxygen will oxidize nitric oxide into nitrogen dioxide, and the collection of NO should avoid contact with air (oxygen), which can be collected by drainage. All right.

Storage and transportation

Shipping precautions.

Precautions for transportation: Railway transportation must be reported to the railway bureau for trial operation, and the trial operation period is two years. After the trial operation, write the trial operation report and submit it to the Ministry of Railways to officially announce the transportation conditions.

The helmet on the cylinder must be worn when transporting the cylinder. The cylinder is generally placed flat, and the bottle mouth should be facing the same direction, not crossed; The height shall not exceed the protective fence of the vehicle, and it shall be clamped with a triangular wooden mat to prevent rolling. It is strictly forbidden to mix and transport with flammable or combustible materials, halogens, edible chemicals, etc.

In summer, it should be transported in the morning and evening to prevent sun exposure. When transporting by road, it is necessary to drive according to the prescribed route, and it is forbidden to stay in residential areas and densely populated areas. It is forbidden to slip when transporting by rail.

Operational precautions.

Tightly sealed, providing adequate local ventilation and full ventilation. Operators must be specially trained and strictly follow operating procedures. It is recommended that the operator wear a self-priming filtering gas mask (half mask), wear chemical safety glasses, a breathable gas protective suit, and wear chemical gloves.

Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Prevent gas leakage into the workplace air.

Avoid contact with halogens. Light loading and unloading during handling to prevent damage to cylinders and accessories. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment.

Precautions for storage.

Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30. It should be stored separately from flammable (combustible) materials, halogens, and edible chemicals, and should not be mixed. The storage area should be equipped with leakage emergency treatment equipment.

Nitric oxide is a diatomic molecule with a linear molecular configuration. In nitric oxide, a bond is formed between nitrogen and oxygen, a 2-electron bond, and a 3-electron bond. The bond between nitrogen and oxygen is that nitrogen and oxygen each have a lone pair of electrons.

With 11 valence electrons, it is an odd electron molecule and is paramagnetic. The inverse bond orbital (2p*)1 is susceptible to loss to form nitrosyl cation NO.

Use. 1. It is used in oxidation and chemical vapor deposition processes in semiconductor production, and is used as a standard mixture for atmospheric monitoring. It is also used in the manufacture of nitric acid and silicone oxide film and carbonyl nitrosyl. It can also be used as a bleaching agent for rayon and a stabilizer for propylene and dimethyl ether.

Supercritical solvents. It is used in the manufacture of nitric acid, nitrosocarboxyl compounds, and bleaching of rayon. It is used as a stabilizer for auxiliary diagnosis and organic reaction in medical clinical experiments.

2. Stabilizing agent for nitric acid, rayon bleach, propylene and dimethyl ether.

Nitric oxideThe chemical formula of の.

Nitric oxide is a nitrogen oxide with the chemical formula NO, relative molecular weight.

Valency of nitrogen.

for 2. It is a colorless and odorless gas, a toxic gas that is difficult to dissolve in water.

Since nitric oxide carries free radicals.

This makes it chemically very lively. When it reacts with oxygen, it forms a corrosive gas, nitrogen dioxide.

NO2), nitrogen dioxide can react with water to form nitric acid.

The equation is: 3NO2+H2O==2HNO3+NO.

Relative to the molecular mass, the valency of nitrogen is +2. It is a colorless and odorless gas, a toxic gas that is difficult to dissolve in water.

Nitric oxide carries free radicals, which makes it chemically very reactive. When it reacts with oxygen, it forms a corrosive gas, nitrogen dioxide (NO2), which reacts with water to form nitric acid. The equation is:

3no2+h2o==2hno3+no。

NO has less solubility in water and does not react with water. At room temperature, NO is easily oxidized to nitrogen dioxide, and can also react with halogens to form halogenated nitrosyl (NOx), such as 2NO+Cl2=2NOCl.

But NO and O2 can react with water, and the chemical equation is 4NO+3O2+2H2O=4HNO3.

Nitric oxide is an inorganic compound with the chemical formula NO, it is a nitrogen oxide with a valency of +2 for nitrogen. It is a colorless gas at room temperature and pressure, slightly soluble in water, soluble in ethanol and carbon disulfide. In the air, it reacts with oxygen to form nitrogen dioxide.
