Acetic acid - Names and Identifiers
|
ntroduction | acetic acid is commonly known as acetic acid (AcOH), which is named because it is the main component of vinegar, as one of the most important fatty acids. In nature, it is generally found in many plants in free or ester form. Formula CH3COOH. Vinegar has been brewed and used for thousands of years. There is a record of vinegar in ancient China. However, concentrated acetic acid was successfully developed by Stahl in 1700. Pure acetic acid is a colorless liquid with a stimulating taste. Melting point 16.6 ºC, boiling point 117.9 ºC, relative density 1. 049 (20/4 ºC). Soluble in water, ethanol, glycerol, ethyl ether and carbon tetrachloride; Insoluble in carbon disulfide. Anhydrous acetic acid solidifies into ice-like at low temperature, commonly known as glacial acetic acid. Corrosive. It is a weak organic acid, which has the ability of acid, and can be esterified with alcohol. |
harmful effects and symptoms | acetic acid (AcOH) is corrosive and irritating to the eyes, respiratory tract, esophagus, stomach, ingestion can cause Vomit, Diarrhea, circulatory system paralysis, and even acidosis, uremia and hematuria, eventually leading to death. Acetic acid is soluble in lipids, so it can be absorbed through the skin, and the penetration of the cells is almost completely absorbed by the human body. Therefore, the damage of acetic acid to the eye mucosa and teeth can be clearly seen. The vapor can irritate eyes, nose, throat and lungs. Inhalation of concentrated vapor can cause severe damage to the nasal, throat and lung membranes. Exposure to concentrated acetic acid can cause serious damage to the skin and eyes, and even cause blindness. Repeated or prolonged exposure to acetic acid irritates the skin, causes darkening, corrodes anterior teeth, and may cause chronic inflammation of the nose, throat, and bronchi. acute overexposure can cause bronchopneumonia and pulmonary edema. Chronic exposure can cause pharyngitis and catarrhal bronchitis. Although intake in industrial production is unlikely, but if taken by mistake, may cause esophageal perforation, hematemesis, Diarrhea, Shock, hemolysis and uremia, if not treated in time, will lead to death. |
