Product Description

Product Description

Nature
At room temperature and pressure, it is a colorless transparent volatile liquid. Volatile, can be miscible with ethanol, ether, acetone, chloroform, glacial acetic acid, carbon disulfide, carbon tetrachloride and oil and other organic solvents. Soluble in water: 23.5ºC, 0.188%cw/w). Benzene is a compound that does not break down easily. Its vapor can form an explosive mixture with air. Encountering high heat or open flame is extremely easy to cause combustion and explosion. Easy to generate and accumulate static electricity. Intense reaction in contact with oxidant.
Use
A standard sample for the determination of refractive index. It can be used as a solvent and cleaning agent for precision optical instruments, electronics industry, organic synthesis, etc.

Can release toxic vapor. Benzene is a compound that is not easy to decompose. When it reacts with other chemical substances, its basic structure is unchanged, only the hydrogen atom in the benzene ring is replaced by other groups. The vapor of benzene can form an explosive mixture with air. Liquid Benzene is lighter than water, but its vapor is heavier than air. It is very easy to cause combustion and explosion in the face of high heat or open fire. Benzene vapor can diffuse far, meet the ignition source on the ignition, and the flame along the flow back. Benzene is prone to the generation and accumulation of static electricity. The reaction of benzene in contact with oxidant is intense. Benzene is insoluble in water, but soluble in alcohol, ether, acetone, chloroform, gasoline, carbon disulfide and other organic solvents.
Use	Basic chemical raw materials, used as solvents and synthetic benzene derivatives, spices, dyes, plastics, pharmaceuticals, explosives, rubber, etc.
