BENZENE
BENZENE
Chemical Formula: C?H?
Molecular Weight: 78.11 g/mol
Description:
Benzene is a clear, colorless, highly flammable aromatic hydrocarbon liquid with a characteristic sweet odor. It is one of the most important petrochemical intermediates, used extensively in the production of numerous industrial chemicals. Benzene serves as a starting material for a wide range of products such as styrene, phenol, aniline, and cyclohexane.
Applications:
-
Chemical Intermediate: Used in the manufacture of styrene, cumene, aniline, alkylbenzenes, and cyclohexane.
-
Solvent: Employed as an industrial solvent in paints, resins, oils, and waxes (limited due to toxicity).
-
Pharmaceuticals: Precursor for various intermediates and active ingredients.
-
Rubber & Plastics: Used in the synthesis of synthetic rubber and plastic resins.
-
Laboratory Reagent: Utilized as a reagent and solvent in research and analytical chemistry.
