Gas Description

Ammonia, Ammonia, NH3, colorless gas. Has a strong irritating odor. The density is 0.7710. The relative density is 0.5971 (air = 1.00). Easily liquefied into a colorless liquid. It can be liquefied by pressing at normal temperature (critical temperature 132.4 ° C, critical pressure 11.2 MPa, which is 112.2 atmospheres). Boiling point is -33.5 ° C. It is also easily solidified into a snow-like solid. Melting point -77.75 ° C. Soluble in water, ethanol and ether. At high temperatures, it will decompose into nitrogen and hydrogen, which has a reducing effect. In the presence of a catalyst, it can be oxidized to nitric oxide. Used for making liquid nitrogen, ammonia, nitric acid, ammonium salts and amines. It can be produced by the direct synthesis of nitrogen and hydrogen, which can burn the mucous membranes of the skin, eyes and respiratory organs. Excessive inhalation by humans can cause lung swelling and even death.

Main Application

1. Used in chemical, food, pharmaceutical and other industries.

2. Liquid ammonia, ammonia, nitric acid, ammonium salts and amines.

3. Fertilizer, refrigerant, chemical raw materials, etc.

4. Used for large-scale integrated circuit decompression or plasma CVD to grow silicon dioxide film.

5. Refrigerant and preparation of ammonium salt and nitrogen fertilizer.

6. Quality assurance and quality control in environmental monitoring and analysis testing can also be used for instrument calibration, method verification and technical arbitration.

What is the difference between Liquid Ammonia and Ammonia Water

Liquid Ammonia

also known as anhydrous ammonia, is a colorless liquid. As an important chemical raw material, ammonia is widely used. Liquid ammonia is mainly used in the production of nitric acid, urea and other chemical fertilizers. It can also be used as a raw material for medicine and pesticides. In the defense industry, liquid ammonia is used to make rocket and missile propellants. It can be used as the raw material of ammoniation of organic chemical products, and can also be used as a refrigerant. For the convenience of transportation and storage, liquid ammonia is usually obtained by pressurizing or cooling the gaseous ammonia. Liquid ammonia is widely used in industry, and it is corrosive and volatile, so the incidence of chemical accidents is quite high.

Ammonia Water

is also called “Anshui”. Its main component is NH3 / H2O. It is an aqueous solution of ammonia gas. It is colorless, transparent and has a pungent odor. Melting point -77 ° C, boiling point 36 ° C, density 0.91g / cm ^ 3. Soluble in water and ethanol. It is volatile and has a basic alkali permeability. It is prepared by passing ammonia gas into water. Toxic, irritating and corrosive to eyes, nose, and skin, can cause suffocation. The maximum allowable concentration in the air is 30mg / m ^ 3. Mainly used as fertilizer.

The difference between liquid ammonia and ammonia water is mainly reflected in the composition, applications and characteristics:

Liquid Ammonia Composition: NH3
Ammonia Water Composition: NH3 / H2O, HN3, H2O, NH4 +, OH-, H +

The main applications of Liquid Ammonia in farms are:

  • First, ammonia itself has a certain bactericidal effect, so some farms use it for sterilization.
  • Second, ammonia can reduce farm temperature. The temperature of the farm is generally high, and the ammonia gas can be passed through the pipeline to prevent the heatstroke and cool down.
  • In addition, liquid ammonia can be used as:
    • Production of nitric acid, urea and other chemical fertilizers. It can also be used as raw materials for medicine and pesticides.
    • In the national defense industry, the propellant used to make rockets and missiles.
    • It can be used as raw material of ammoniation of organic chemical products, and can also be used as refrigerant.
    • Liquid ammonia is heated to 800 ~ 850 ℃, and ammonia is decomposed under the action of nickel-based catalyst to obtain a hydrogen-nitrogen mixed gas containing 75% H2 and 25% N2. The gas produced by this method is a good protective gas, which can be widely used in the semiconductor industry, metallurgical industry, and other industries and scientific research that require a protective atmosphere.
  • Ammonia Water Applications:
    • In industry, ammonia gas is used to produce nitric acid through oxidation, and nitric acid is an important chemical raw material.
    • Manufacture fertilizer.
    • Ammonia is an important reagent in the laboratory.
    • As an alkaline disinfectant in the military, it is used for disinfecting sarin-type poisons. The commonly used is 10% concentration of dilute ammonia water (density 0.960), and the winter concentration is 20%.
    • The inorganic industry is used for the preparation and selection of various iron salts.
    • Wool spinning, silk, printing and dyeing and other industries are used for washing wool, woolen cloth, grey cloth, dissolving and adjusting pH, and as dyeing aid. The organic industry is used as an aminating agent and a catalyst for the production of thermosetting phenolic resins.
    • In medicine, dilute ammonia is used to stimulate respiration and circulation, treat fainting and fainting, and be used as skin irritant and disinfectant. It is also used as detergent, neutralizer, alkaloid extractant, and also used in pharmaceutical industry, gauze industry, blueprint, etc.
  • The characteristics of Liquid Ammonia and Ammonia Water:
    Liquid ammonia is liquefied ammonia (Ammonia in Liquid State), which is pure and contains only ammonia molecules. Ammonia Water is formed by dissolving ammonia in water and is a mixture.
