Product Name: ethanol (ethanol) Level: AR / CP
Implementation of the standards: GB / T 678-2002
Molecular formula: CH3CH2OH
Properties: This reagent is colorless transparent liquid, volatile, with mixed water, chloroform, ether, etc., easy to absorb water.
Hazardous characteristics: flammable vapor and air can form explosive mixtures case of fire, high-heat combustion caused the explosion. Contact with the oxidant chemical reaction or cause a fire. 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, acids, acid anhydrides, alkali metals, amines.
