Product Name: Toluene Level: AR / CP
Implementation of the standards: GB / T 684-1999
Molecular formula: C6H5CH3
Properties: This reagent is colorless transparent liquid, insoluble in water, ethanol, ethyl ether, chloroform and other organic solvents miscible flammable.
Hazardous characteristics: flammable vapor and air can form explosive mixtures case of fire, high-heat combustion caused the explosion. It can react with oxidants. Velocity too fast, easy and accumulation of static electricity. Its vapor is heavier than air and can spread to the lower Department of considerable local, fire source will fire back.
Materials to avoid: flammable or combustible materials, strong reducing agents, copper, iron, iron, zinc, active metal powder.
