InChI: InChI=1/C4H8O/c1-3-4(2)5/h3H2,1-2H3
Product description:
Physicochemical properties Color and odor status: colorless and transparent liquid with acetone-like odor
Toxicity: low toxicity Flammability: flammable
Density: 0.806 Volatility: Volatile
Corrosivity: Corrosive Boiling point: 76.9 ℃
Stability: relatively stable to heat Melting point: -85.9 ℃
Auto-ignition point: 515.6℃ Flash point: -9 ℃ (CC)
Decomposition: Under the action of a strong oxidant, the carbonyl group is oxidized to cut the chain to generate formic acid, propionic acid and acetic acid
Solubility: miscible with ethanol, ether, benzene, chloroform and oil. Soluble in 4 parts of water, but the solubility decreases as the temperature increases, and can form an azeotrope with water
Uses As a solvent and dewaxing agent, it is also used in a variety of organic synthesis, and as a raw material for synthetic fragrances and medicines
Hazard category Flammable liquid with flash point in class 3.2
Fire-fighting measures Fight fire with water spray, dry chemical, foam or carbon dioxide. Avoid using direct-flow water to put out the fire. Direct-flow water may cause the splash of flammable liquids, which may spread the fire. Firefighters must wear air-carrying respirators and full-body fire-fighting suits. To put out the fire in the upwind direction,
move the container from the fire site to an open area as much as possible . Evacuate immediately if the container in the container has discolored or emits sound from the safety pressure relief device
Emergency treatment Skin Contact: Remove contaminated clothing and rinse skin thoroughly with soap and water.
Eye Contact: Lift eyelids and rinse with running water or saline. Get medical attention
Inhalation: Get out of the scene quickly to fresh air. Keep the airway open. If breathing is difficult, give oxygen
, stop breathing, and give artificial respiration immediately. Medical treatment
Ingestion: drink enough warm water, induce vomiting, gastric lavage with water or 1% sodium thiosulfate solution. seek medical treatment
Packaging, storage, transportation Packed in iron drums, 160kg/drum, 800kg/IBC TANK bulk water tanker, stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30℃. Keep the container sealed
Transport: Transport according to the requirements of dangerous goods
This product is a precursor chemical
