Benzene 99.9%
Benzene 99.9% is a high-purity aromatic hydrocarbon, critical as a basic building block in the chemical industry.
Description
Benzene (CAS 71-43-2, chemical formula C6H6) is a fundamental organic chemical belonging to the aromatic hydrocarbons. In its 99.9% purity grade, it is a clear, colorless, highly flammable liquid with a characteristic sweet odor. Its unique conjugated ring structure, consisting of six carbon atoms joined in a ring with one hydrogen atom attached to each, confers exceptional stability and reactivity beneficial for various industrial syntheses. Benzene serves as an indispensable precursor for multitudinous downstream chemicals, polymers, and other materials. The high purity ensures consistent performance in applications where minimal impurities are critical. Its industrial production primarily involves catalytic reforming of petroleum fractions and the disproportionation of toluene. Strict quality control measures ensure the stringent purity requirements are met for demanding chemical manufacturing processes.
Applications
Benzene is a cornerstone chemical in the petrochemical industry, primarily used as an intermediate in the synthesis of numerous commercial products. Major applications include the production of ethylbenzene, a precursor to styrene (used in polystyrene and synthetic rubber); cumene, for phenol and acetone production (utilized in resins, plastics, and solvents); and cyclohexane, essential for nylon manufacturing (fibers, engineering plastics). It is also a feedstock for maleic anhydride, chlorobenzenes, and alkylbenzenes, which find use in detergents, pesticides, pharmaceuticals, and dyes. Its role as a solvent is diminishing due to health concerns, but it remains a vital chemical building block.
Storage & Handling
Store in cool, well-ventilated areas away from direct sunlight, heat sources, and incompatibles. Keep containers tightly closed. Benzene is highly flammable; take measures to prevent static charge. Handling requires personal protective equipment and local exhaust ventilation to minimize exposure.
Danger
