Descripción del producto
used as a solvent and chemical intermediate for dyes, pigment,
agrochemicals and wide range of organic synthesis ;
meta-,
colorless liquid boiling at **2 C, used as a solvent and chemical
intermediate;
para-, white solid with a with a
characteristic penetrating odor. It is used mainly as an
insecticidal fumigant against moths, as a space deodorizer, as a
general insecticide and fungicide on crops, and as a chemical
intermediate for plastics, dyes, pharmaceuticals and other organic
compounds. All they are insoluble in water and denser than water.
They are prepared by the chlorination reaction of benzene in the
presence of iron(III) chloride. (the chlorination under strong
illumination and without iron(III) chloride leads to benzene
hexachloride instead of mono or polychlorobenzenes). The
chlorination reaction leads to similar ratio of
ortho- and
para-dichlorobenzene, but small amount of the
meta isomer is performed. The
ortho and
para isomers are separated by fractional freezing. While
the
para isomer crystallizes, the
ortho isomer
remains liquid. The
meta-dichlorobenzene is prepared by
heating and pressure with aluminum chloride. p-Dichlorobenzene is
used mainly as an insecticidal fumigant against moths, as a space
deodorizer, as a general insecticide and fungicide on crops, and as
a chemical intermediate for 2,*-dichloroaniline, plastics (e.g
polyphenylene sulfide resins used for surface coatings and molding
resins), dyes, pharmaceuticals, agrochemicals and other organic
synthesis
