Molecular formula
Product Name
Sodium hydroxide; caustic soda; caustic soda; caustic soda; Sodium hydroxide; CAS: 1310-73-2
Physicochemical properties
Molecular formula NaOH. The molecular weight is 40.01. The relative density is 2.13. The melting point is 318. Rapidly absorbing water from the air also absorbs carbon dioxide rapidly. It is soluble in water, ethanol and glycerin. A large amount of heat is produced when dissolving. These solutions also produce large amounts of heat when mixed with acids.
Contact opportunity
It is widely used as a neutralizer. It is used to make various kinds of sodium salt, soap, cellophane, viscose fiber and rubber products.
The main manufacturers in China: Qilu Petrochemical Industries Co chlor alkali plant, Shanghai chlor alkali plant, Shanghai electric plant, Shanghai Tianyuan Chemical Plant, Tianjin chemical plant, Beijing chemical plant, Shenyang chemical plant, Dagu chemical plant, Jinxi Chemical General Plant, Fuzhou second chemical plant, Zhuzhou Chemical Plant, Quzhou chemical plant, electric chemical plant, Wuhan Gedian Chemical plant, Chongqing Tianyuan Chemical Plant, Guangzhou chemical plant, Qingdao chemical plant, Xi'an chemical plant, Taiyuan chemical plant, Changzhou chemical plant, Siping chemical plant, Nanning chemical plant, Jilin tourmaline plant, Yibin chemical plant, Jiujiang chemical plant, Nanjing chemical plant, longevity Chemical Plant, Guizhou Zunyi alkali factory, Guizhou chemical plant, Yunnan chemical plant
Intrusion pathway
Invasion of the respiratory tract, the digestive tract and the skin.
A brief introduction to toxicology
LD50: 40 mg/kg in the abdominal cavity of mice. The rabbit was LDLo: 500 mg/kg through the mouth.
It has a dissolving effect on protein and strong corrosiveness. It has strong stimulation and corrosiveness to skin and mucosa. Corneal injury can be caused by dropping 0.02% solution into rabbit eyes.
Clinical manifestation
Inhalation of sodium hydroxide dust or smoke can cause chemical upper respiratory tract inflammation.
Skin contact can cause burns.
After oral administration, burns, pain, colic, vomiting, bloody stomach contents and bloody diarrhea are seen in the mouth, esophagus and stomach. Sometimes there is hoarseness, dysphagia, shock, and perforation of the digestive tract. Gastrointestinal tract stenosis may occur at the later stage.
Sodium hydroxide splashes into the eyes, causing conjunctivitis, conjunctival edema, conjunctiva and corneal necrosis. A serious person can cause blindness.
Skin pollution can be rinsed thoroughly with clean water. When splashing into the eye, quickly rinse with a large amount of water. It is not neutralized with acid liquid.
See "treatment of chemical skin burns" and "chemical eye burns".
Patients with oral poisoning should be given vinegar, 3 to 5% acetic acid or 5% diluted hydrochloric acid, a large amount of orange juice or lemon juice. Later, egg white, olive oil, or other vegetable oils. Taboos emetic and gastric lavage. Appropriate infusion to correct dehydration, electrolyte imbalance and shock. Esophageal stricture should be prevented. Esophagus dilatation should be done as soon as possible after the risk period of perforation.
