1.It is the intermediate of fungicide azoxystrobin, azoxystrobin and herbicide Sulfuron methyl.
2.It is used as catalyst, resin crosslinker, resin curing accelerator, resin and rubber additive.
3.It can be used as solvent of cellulose acetate, ink and pigment, additive of gasoline and lubricant, desiccant of paint and varnish.
Solvent: It is used as a solvent in organic synthesis and in the formulation of paints, coatings and adhesives.
Reagents in organic chemistry: Acetylacetone is commonly used as a reagent in organic synthesis, especially in the formation of metal complexes, and as a ligand in coordination chemistry.
Synthetic Precursor: It is a precursor for the synthesis of various organic compounds, including drugs and agrochemicals.
PH indicator: Acetylacetone can act as a pH indicator in certain chemical reactions.
Flavoring: Due to its sweet, fruity aroma, it is sometimes used in flavoring and spice formulations.
Analytical Chemistry: Used in analytical chemistry to determine certain metal ions through complexation.
It can be mixed with ethanol, ether, chloroform, acetone, glacial acetic acid and other organic solvents, soluble in water.
1. Keep away from open flames and strong oxidants, and keep in a cool place.
2. Fireproof and moisture-proof, stored in dangerous goods warehouse.
Store and transport in accordance with hazardous chemicals regulations.
Container: Use airtight containers made of glass or compatible plastic to prevent contamination and evaporation.
Temperature: Store acetylacetone in a cool, dry place away from direct sunlight and heat sources. Ideally, it should be kept at room temperature.
Ventilation: Make sure the storage area is well ventilated to avoid vapor accumulation.
Incompatibility: Acetylacetone should be kept away from strong oxidants, acids and bases as it may react with these substances.
Label: Clearly label containers with the chemical name, concentration, and any relevant hazard information.
1. Properties: Acetylacetone is a colorless or slightly yellow flammable liquid. Boiling point is 135-137℃, flash point is 34℃, melting point is -23℃. The relative density is 0.976, and the refractive index is n20D1.4512. 1g of acetylacetone is soluble in 8g of water, and is miscible with ethanol, benzene, chloroform, ether, acetone and glacial acetic acid, and decomposes into acetone and acetic acid in lye. It is easy to cause combustion when exposed to high heat, open flames and strong oxidants. It is unstable in water and is easily hydrolyzed into acetic acid and acetone.
2. Moderate toxicity. It can irritate the skin and mucous membranes. When the human body stays for a long time under (150~300)*10-6, it can be harmed. Symptoms such as headache, nausea, vomiting, dizziness, and dullness will appear, but it will be affected when the concentration is 75*10-6. No danger. The production should adopt vacuum sealing device. Ventilation should be strengthened at the operation site to minimize running, leaking, dripping and leakage. In case of poisoning, leave the scene as soon as possible and breathe fresh air. Operators should wear protective gear and conduct regular occupational disease inspections.
Yes, acetylacetone can be considered a hazardous material. Here are some key points about its hazards:
1. Flammability: Acetylacetone is flammable and may present a fire hazard if exposed to heat, sparks or open flame.
2. Health Hazard: It is irritating to the skin, eyes, and respiratory system. Inhalation of vapor may cause respiratory irritation. Long-term or repeated contact may cause more serious harm to health.
3. Toxicity: Although acetylacetone is not a highly toxic substance, it still needs to be handled with care. Ingestion or high-level exposure may cause adverse health effects.
4. Environmental Hazards: Acetylacetone may be harmful to aquatic life and should be handled properly to minimize impact on the environment.
When working with acetylacetone, always use appropriate personal protective equipment (PPE), such as gloves and goggles, and work in a well-ventilated area or under a fume hood. Always refer to the Material Safety Data Sheet (MSDS) for specific safety information and handling instructions.
1. Packaging: Use appropriate containers that are compatible with acetylacetone. The container should be tightly sealed to prevent leakage and evaporation. Use a secondary containment device (such as a spill pan) to catch any potential leaks.
2. Label: Clearly label all containers with the chemical name, hazard symbol and any relevant safety information. Ensure labeling complies with local and international regulations.
3. Transportation Regulations: Comply with all applicable regulations for the transportation of dangerous goods. This may include following guidelines established for air transportation by organizations such as the U.S. Department of Transportation (DOT) or the International Air Transport Association (IATA).
4. Temperature Control: During transportation, acetylacetone should be kept away from heat sources and direct sunlight. It should be stored in a cool and dry place to minimize the risk of flammability.
5. Avoid Mixing: Do not transport acetylacetone together with incompatible materials (such as strong oxidizers or acids) to prevent dangerous reactions.
6. Personal Protective Equipment (PPE): Ensure that personnel responsible for transporting acetylacetone wear appropriate PPE, including gloves, goggles, and protective clothing.
7. Emergency Procedures: Have emergency procedures in place in case a spill or leak occurs during transport. This includes having a spill kit ready at all times and ensuring personnel are trained in emergency response.
