| Description | Ammonia, also known as anhydrous ammonia is a colorless liquid with a strong pungent odor. Ammonia as an important chemical raw material, for transport and storage facilities, gaseous ammonia is usually obtained by pressurized liquid ammonia or cooling. Ammonia soluble in water, soluble in water to form an ammonium ion NH4 +, hydroxide ions OH-, alkaline alkaline solution. Multi-pressure liquid ammonia storage in cylinders or steel tank, and can not coexist with acetaldehyde, acrolein, boron and other substances. Ammonia is widely used in industry, corrosive and volatile, so its high chemical accidents. |
| Usage | Ammonia mainly for the production of nitric acid, urea and other chemical fertilizers, also used as a raw material medicine and pesticide. In the defense industry, rockets, missile propellant used in the manufacture. Ammoniated organic chemical products used as raw material, because ammonia into the air after the vaporization of ammonia, can absorb a lot of heat, known as "refrigerants" while ammonia has a bactericidal effect, so in poultry in the industry, is used for sterilization and cooling refrigeration. Satin Liquid ammonia can also be used in textile finishing. |
| Precautions | 1, irritating ammonia is reliable harmful concentration alarm signal. However, due to olfactory fatigue after long-term exposure to low concentrations of ammonia will be difficult to detect. Mild inhalation of ammonia poisoning manifestations of rhinitis, pharyngitis, tracheitis, bronchitis, acute inhalation of ammonia poisoning occurs by many as the pipe rupture accident, caused by a valve burst. Acute ammonia poisoning mainly for respiratory tract irritation and burns. Severe inhalation poisoning can occur laryngeal edema, glottis and respiratory mucosa narrow loss, can cause airway obstruction, causing suffocation. 2, the eye and low concentrations of ammonia in the wet skin can rapidly produce a stimulating effect. Moist skin or eye exposure to high concentrations of ammonia can cause severe chemical burns. High concentrations of vapor has a strong irritant to the eyes, can cause pain and burns, cause significant inflammation and edema may occur, epithelial tissue damage, corneal opacity and iris inflammation. |
