Benzene

Benzene is an organic compound that is a colorless or light-yellow liquid that has a relatively high melting point. The word benzene derives historically from gum benzoin, sometimes called benjamin. It is highly flammable, has a sweet odor and quickly evaporates into air. Its vapor is heavier than air, which makes it sink into low-lying areas. Benzene dissolves only slightly in water and floats on top of it.Benzene is formed from both natural and man-made processes. Natural sources include volcanoes and forest fires. Benzene is also a natural constituent of crude oil and gasoline. Its most widely-produced derivatives include styrene, which is used to make polymers and plastics, phenol for resins and adhesives and cyclohexane, which is used to manufacture Nylon. About 80% of benzene is consumed in the production of three chemicals, ethylbenzene, cumene, and cyclohexane. Its most widely produced derivative is ethylbenzene, precursor to styrene, which is used to make polymers and plastics.

Benzene Chloride

Benzene chloride is an aromatic organic compound. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals. The major use of chlorobenzene is as an intermediate in the production of commodities such as herbicides, dyestuffs, and rubber. Chlorobenzene is also used as a high-boiling solvent in many industrial applications as well as in the laboratory.

Benzenesulfonic Acid

Benzenesulfonic acid is an organic compound. It is the simplest aromatic sulfonic acid. The alkali metal salt of benzenesulfonic acid is used in the production of phenol and resorcinol. Benzenesulfonic acid is also used as an acidic catalyst in esterification and dehydration reactions. A variety of pharmaceutical drugs are prepared as salts of benzenesulfonic acid and are known as besylates or besilates.

Properties Suppliers
Benzil

Benzil is the organic compound and one of the most common diketones.Its main use is as a photoinitiator in polymer chemistry. Benzil used in the preparation of Phenytoin.

Properties Suppliers
Benzoic Acid

Benzoic acid is the simplest aromatic carboxylic acid.It consists of a carboxyl group attached to a phenyl group.Its salts are used as a food preservative and benzoic acid is an important precursor for the synthesis of many other organic substances.It is primarily used in manufacturing of alkyd resins, phenol, sodium benzoate and other organic benzoates,food industry.

Properties Suppliers
Benzoic Acid Methyl Ester

Benzoic Acid Methyl Ester is an ester.It is formed by the condensation of methanol and benzoic acid, in presence of a strong acid such as hydrochloric acid.It is used as a source of benzoyl radical.It is also used in perfumery,as a solvent and pesticide.

Properties Suppliers
Benzoin

Benzoin is an organic compound consisting of an ethylene bridge flanked by phenyl groups and with hydroxyl and ketone functional groups.It appears as off-white crystals, with a light camphor odor. Benzoin is synthesized from benzaldehyde in the benzoin condensation.It is a photocatalyst in photopolymerization and photoinitiator.It is the raw material for synthesis of benzil by organic oxidation with nitric acid or oxone.

Properties Suppliers
Benzophenone

Benzophenone is a widely used building block in organic chemistry, being the parent diarylketone. It can be used as a photo initiator in UV-curing applications such as inks, imaging, and clear coatings in the printing industry. Benzophenone prevents ultraviolet (UV) light from damaging scents and colors in products such as perfumes and soaps. It can also be added to the plastic packaging as a UV blocker. Its use allows manufacturers to package the product in clear glass or plastic. Without it, opaque or dark packaging would be required.

Properties Suppliers
Benzotrifluoride

Trifluorotoluene is an organic compound. This colorless fluorocarbon is used as a specialty solvent in organic synthesis and an intermediate in the production of pesticides and pharmaceuticals. As a solvent, trifluorotoluene is useful in mild Lewis-acid catalyzed reactions, such as the Friedel-Crafts preparations. The most common catalyst, aluminium trichloride reacts with trifluorotoluene at room temperature, however zinc chloride does not. A second and perhaps more valuable use of trifluorotoluene is as a synthetic intermediate. A derivative of trifluorotoluene, 3-aminobenzotrifluoride, is the precursor to the herbicide fluometuron, 1,1-dimethyl-3-(a,a,a-trifluoro-m-tolyl)urea.

Properties Suppliers
Benzoyl Chloride

Benzoyl chloride is an organochlorine compound. It is mainly useful for the production of peroxides but is generally useful in other areas such as in the production of dyes, perfumes, pharmaceuticals, and resins.
