Ethanol (ethanol), organic compound, molecular formula C2H6O, structural formula CH3CH2OH or C2H5OH, commonly known as alcohol.
Ethanol has a wide range of uses. Ethanol can be used to make acetic acid, beverages, flavors, dyes, fuel, etc. Medically, ethanol with a volume fraction of 70% to 75% is also commonly used as a disinfectant, etc., which has a wide range of uses in defense chemical industry, medical and health, food industry, industrial and agricultural production
70% to 75% alcohol is used for disinfection. This is because too high a concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria and making it difficult to kill the bacteria completely. If the alcohol concentration is too low, although it can enter the bacteria, it cannot coagulate the protein in the body, nor can it completely kill the bacteria. Among them, 75% alcohol has the best disinfection effect.
Hazard: Ethanol is flammable and irritating. The vapor and air can form an explosive mixture, which can cause combustion and explosion in case of open flames and high heat energy. Contact with oxidant to cause chemical reaction or cause combustion. In a fire, a heated container is in danger of explosion. Its vapor is heavier than air, and can spread to a relatively far place in the lower place.
Health hazards: This product is a central nervous system inhibitor. First cause excitement, then suppress.
Route of invasion: inhalation, ingestion, percutaneous absorption.
Acute poisoning: Acute poisoning occurs mostly by oral administration. Generally, it can be divided into four stages: excitement, hypnosis, anesthesia and asphyxia. The patient entered the third or fourth stage with loss of consciousness, dilated pupils, irregular breathing, shock, heart failure and respiratory arrest.
Chronic effects: Long-term exposure to high concentrations of this product during production can cause irritation of the nose, eyes, and mucous membranes, as well as headache, dizziness, fatigue, irritability, tremor, and nausea. Long-term alcoholism can cause polyneuropathy, chronic gastritis, fatty liver, liver cirrhosis, myocardial damage, organic psychosis, etc. Long-term skin contact can cause dryness, scaling, chapping and dermatitis.
