  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
