Question 1: Do you smell toxic ethyl acetate every day? Ethyl acetate is toxic It is a colorless and transparent liquid. It smells like fruit. Changeable. Sensitive to air. It can absorb water, and water can make it decompose slowly, showing an acidic reaction. It is miscible with chloroform, ethanol, acetone and ether and soluble in water (10%ml/ml). Can dissolve some metal salts (such as lithium chloride, cobalt chloride, zinc chloride, ferric chloride, etc. ). The relative density is 0.902. Melting point -83℃. The boiling point is 77℃. The refractive index is 1.35438+09. The flash point is 7.2℃ (open cup). Flammable. Steam can form an explosive mixture with air. The median lethal dose (oral) of rats was 1 1.3ml/kg. Have * * * sex.

Emergency treatment

Inhalation: leave the scene quickly and go to a place with fresh air. Keep the respiratory tract unobstructed. If you have difficulty breathing, give oxygen. If breathing stops, give artificial respiration immediately. See a doctor. Eating by mistake: drink plenty of warm water, induce vomiting and seek medical attention. Skin contact: take off contaminated clothes and rinse skin thoroughly with soapy water and clean water. Eye contact: Lift eyelids and rinse with running water or normal saline. See a doctor.

Matters needing attention

1. Health hazard: it has * * effects on eyes, nose and throat. High concentration inhalation can be used for anesthesia, acute pulmonary edema and liver and kidney injury. Continuous inhalation in large quantities can cause respiratory paralysis. People who take it by mistake may have symptoms such as nausea, vomiting, abdominal pain and diarrhea. Sensitization, gingival bleeding caused by vascular nerve disorder; Can cause eczema-like dermatitis. Chronic effects: Long-term exposure to this product sometimes leads to corneal opacity, secondary anemia and leukocytosis. 2. Explosion hazard: This product is flammable, sensitive and allergic.

Question 2: Is ethyl acetate poisonous? Toluene and health hazards.

Invasion route: inhalation, ingestion and percutaneous absorption.

Health hazards: toxic to skin and mucous membrane, and anesthetic to central nervous system.

Acute poisoning: Inhalation of high concentration of this product in a short time can cause obvious eye and upper respiratory symptoms, conjunctival and pharyngeal congestion, dizziness, headache, nausea, vomiting, chest tightness, limb weakness, gait staggering and confusion. In severe cases, restlessness, convulsions and coma may occur.

Question 3: Is ethyl acetate poisonous? Is it edible? What is the lethal dose? A small amount of ethyl acetate is non-toxic and can be used as a food additive with a fruity taste.

Too much will be harmful to your health.

Health hazard: it has * * effects on eyes, nose and throat. High concentration inhalation can cause progressive anesthesia, acute pulmonary edema and liver and kidney damage. Continuous inhalation in large quantities can cause respiratory paralysis. People who take it by mistake may have symptoms such as nausea, vomiting, abdominal pain and diarrhea. Sensitization, gingival bleeding caused by vascular nerve disorder; Can cause eczema-like dermatitis. Chronic effects: Long-term exposure to this product sometimes leads to corneal opacity, secondary anemia and leukocytosis.

Question 4: How toxic is ethyl acetate to people? Belonging to the category of low toxicity.

Acute toxicity: LD50: 5620 mg/kg (taken orally by rats); 4940mg/kg (taken orally by rabbits); LC50:5760/m3 for 8h (inhaled by rats); Inhalation of 2000ppm×60 minutes by human causes serious poisoning reaction; People inhale 800ppm and have symptoms; People inhale 400ppm for a short time, and there are * * * in eyes, nose and throat.

Subacute and chronic toxicity: guinea pigs inhaled 2000ppm, or 7.2g/m3, and 65% of them were exposed, which had no obvious effect; Rabbits inhaled 16000mg/m3× 1 hour/day× 40 days, anemia, leukocytosis, organ edema and steatosis.

In addition, ethyl acetate is flammable and explosive. Its steam can form an explosive mixture with air. Fire and high temperature can cause combustion and explosion. A violent reaction will occur when it comes into contact with oxidant. In a fire, the heated container is in danger of explosion. Its vapor is heavier than air, and it can spread to a considerable distance at a lower place, which will lead to tempering when it meets an open flame.
