As an Ethyl Acetate Plant, share with you. Ethyl acetate is one of the
simplest carboxylic acid esters. The colorless liquid has a sweet fruity taste,
which most people find very pleasant.
As you might expect, ethyl acetate was first synthesized from ethanol and
acetic acid. This reaction is a classic acid-catalyzed Fischer esterification
reaction, dating back to 1895. This is still the most widely used commercial
synthesis method. Another method is the Tishchenko reaction, in which
acetaldehyde is disproportionated into alcohol and acid in the presence of a
base, and then esterified in situ.
Ethyl Acetate Production Technology
Ethyl acetate is a widely used solvent, especially for paints, varnishes,
varnishes, detergents and perfumes. Just like last week's MOTW, methylene
chloride is used as a solvent for decaffeinated coffee beans. In the laboratory,
ethyl acetate is a common solvent for column chromatography and thin layer
chromatography.
Dangerous characteristics
Flammable, its vapor and air can form an explosive mixture. Exposure to open
flames and high heat can cause combustion and explosion. It will react violently
on contact with oxidants. In the fire scene, the heated container is at risk of
explosion. Its vapor is heavier than air, and can spread to a considerable
distance in a lower place, and it will cause backflame in case of open
flame.
Combustion (decomposition) products: carbon monoxide, carbon dioxide.
On-site emergency monitoring method: gas detection tube method
Laboratory monitoring method: non-pump sampling gas chromatography
(WS/T155-1999, workplace air)
Steam may cause drowsiness and dizziness. Prolonged contact may cause dry and
cracked skin.
Emergency treatment
Inhalation: quickly leave the scene to fresh air. Keep the airway open. If
breathing is difficult, give oxygen. If breathing stops, give artificial
respiration immediately. Seek medical attention.
Ingestion: Drink enough warm water, induce vomiting, and seek medical
attention.
Skin contact: Take off contaminated clothing and wash skin thoroughly with
soap and water.
Eye contact: Lift the eyelid and rinse with running water or saline. Seek
medical attention.
Extinguishing agent: alcohol-resistant foam, carbon dioxide, dry powder,
sandy soil. Extinguishing with water is ineffective.
Precautions for fire fighting: Water can be used to keep the container in the
fire scene cool.
