Uses
Mainly used as solvents, anesthetics and chemical reagents
3.6-6.5% of the ether can lead to coma, anesthesia
7-10% of the ether can lead to respiratory arrest
More than 10% of the ether will lead to human death
Formula C4H10O, structural formula CH3CH2-O-CH2CH3 is a colorless volatile liquid with a special smell, use should be avoided sources of ignition, pay attention to safety.
Ether is slightly soluble in water, can dissolve a variety of organic matter is a good organic solvent. Pure ether is used as a general anesthetic for surgery. Industrial ether can be obtained by intermolecular dehydration of ethanol:
With the development of the petroleum industry, ether can also be obtained from petrochemical products ethylene, the method is to use sulfuric acid to absorb ethylene, the formation of ethyl sulfate, and then hydrolyzed to get ethanol and ether. By changing the temperature and reagent concentration
, the proportion of alcohol and ether can be controlled.
To purchase anhydrous ether, you need to apply for a purchase license from your local public security office.
Ether is slightly soluble in water, and anhydrous ether is different. Ether is a toxic substance, long breathing ether gas can make the respiratory organs are stimulated, inflammation, memory loss, produce decadent mood. Drinking 30-60 ml of ether can kill you. When burning, ether produces poison, which can make people unconscious and even die. Ether acute poisoning shows excitement in the early stage, then causes anesthesia, vomiting, and then cyanosis, body temperature drops, cold limbs, sometimes it will suddenly stop breathing, pulse is weak, pupils are dilated, but it will not die, so it is less dangerous to be used as anesthetics. Severe acute poisoning will cause vomiting, coughing, weakness, and often complicate nephritis, bronchitis and pneumonia. Poisoned persons should be evacuated from the scene, moved to fresh air, pay attention to patient insulation, oxygen transfusion, extended medical treatment. Production equipment should be strictly sealed and the site should be well ventilated. Operators should wear good protective gear and undergo regular medical checkups. The maximum permissible concentration in the air is 1200mg/L.
