Product Name: ether Level: AR / CP
Implementation of the standards: GB / T 12591-2002
Molecular formula: (CH3CH2) 2O
This reagent is transparent colorless volatile liquid, flammable, narcotic. In the case of light or air oxidized to peroxide. Mixing the organic solvent with an alcohol, benzene, chloroform, etc., having a boiling point of 35 ℃
Hazardous characteristics: its vapor and air can form explosive mixtures case of fire, explosion fever burns easily. It can react with oxidants. In the air long after the home can generate explosive peroxides. In the scene, heating containers risk of explosion. Its vapor is heavier than air and can spread to the lower Department of considerable local, fire source will fire back.
Incompatibility: Strong oxidizing agents, oxygen, chlorine, perchlorate.
