Product Details

Chlorobenzene CAS# 108-90-7

Chlorobenzene is a monocyclic fragrant compound with one hydrogen atom on the benzene ring substituted with one chlorine. It is produced by means of chlorination of benzene in the liquid segment with a catalyst. Chlorobenzene is a colourless, flammable liquid with a candy almond-like odor, at ambient temperature with a incredibly excessive vapour pressure, reasonable octanol-water partition coefficient (log 2.8) and average to low water solubility (497.9 mg/L @ 25℃). Chlorobenzene has a excessive solubility in nonpolar solvents, however, it is nearly insoluble in water. Technical grade Chlorobenzene is commonly 99% pure with < 0.05% benzene and < 0.1% dichlorobenzenes as contaminants. It is a frequent solvent and a extensively used intermediate in the manufacture of different chemicals. Rhodococcus phenolicus is a bacterium species capable to degrade chlorobenzene as sole carbon sources.

Product Usage

1.Chlorobenzene is used particularly as uncooked cloth for the synthesis of o- and p-nitrochlorobenzene and 2,4-dinitrochlorobenzene.Important quantitative chemical conversions different than the manufacturing of nitrochlorobenzenes are the manufacturing of diphenyl oxide and diphenyldichlorosilane.

2.Chlorobenzene is mostly used as uncooked cloth for the synthesis of chemical compounds together with triphenylphosphine (catalyst for natural synthesis), phenylsilane, and thiophenol (pesticide and pharmaceutical intermediate). It is additionally used as uncooked fabric for the synthesis of solvent for natural synthesis reactions together with methylenediphenyldiisocyanate, urethane uncooked material, agricultural adjuvants, paint and ink, and cleansing solvent for electronics.

3.manufacture of phenol, aniline, DDT; solvent for paints; warmth switch medium.

4.Chlorobenzene is used as a system solvent in the manufacturing of isocyanates such as MDI and TDI and as a solvent in a variety of crop safety formulations. It is similarly used as a solvent in condensation reactions in the dyes industry.
