Product Name: Methanol Level: AR / CP
Implementation of the standards: GB / T 683-2006
Molecular formula: CH3OH
Properties: This reagent is colorless transparent liquid, miscible with water, alcohols, ethers, etc.
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: acids, anhydrides, strong oxidizing agents, alkali metals.
