Essential information

Nitric acid is a strong acid with strong oxidizing and corrosive properties, belonging to the category of inorganic strong acids. It is one of the six major inorganic strong acids and an important chemical raw material. It can be used in industry to produce fertilizers, pesticides, explosives, dyes, salts, etc; In organic chemistry, a mixture of concentrated nitric acid and concentrated sulfuric acid is an important nitration reagent, and its aqueous solution is commonly known as nitrate solution or ammonia nitrogen solution. The hazard symbols are O (oxidizing agent) and C (corrosive).

Application area 

Nitric acid is an important chemical raw material, mainly used to manufacture compound fertilizers such as ammonium nitrate, ammonium calcium nitrate, nitrophosphate, nitrogen phosphorus potassium, etc. As an essential raw material for producing nitrate nitrogen fertilizers (such as ammonium nitrate, potassium nitrate, etc.), aqua regia, nitroglycerin, nitrocellulose, nitrobenzene, picric acid, and nitrate esters, it is also used to produce explosives containing nitro groups.
 
Organic industry
Used for manufacturing nitro compounds such as tetranitromethane, nitrohexane, l-nitropropane, and 2,4-dinitrophenyloxyethanol.
  
Dye industry
Used for the synthesis of dye intermediates such as p-nitroanisole, 4,4 '- dinitrodiphenyl ether, p-nitrophenol, and 2,5-dichloronitrobenzene.
 
 
Paint industry
Used for manufacturing nitrocellulose varnish and nitrocellulose enamel.
 
Pharmaceutical industry
Used for manufacturing nitroacetophenone.
 
water treatment
 Nitric acid can be used as a cleaning and rust removal agent for carbon steel and stainless steel equipment, and is used in the oxidation-reduction treatment process of sewage and wastewater. In the biological treatment process of sewage, it can be used as a nitrogen source for microbial nutrients.
 Other functions
Nitric acid, as an oxidant, can oxidize alcohols, aniline, and other chemicals. And it has been used as a propellant for rockets. Nitric acid is also a raw material for the production of nitrates such as calcium, copper, silver, cobalt, and strontium.

Packaging, Storage, Transportation, and Safety

Sealed operation, pay attention to ventilation. Operate as mechanically and automatically as possible. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter type gas masks (full face masks), rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Prevent steam leakage into the workplace air. Avoid contact with reducing agents, bases, alcohols, and alkali metals. Handle with care during transportation to prevent damage to packaging and containers. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances. When diluting or preparing a solution, acid should be added to water to avoid boiling and splashing.
