  2. 2-Nitrochlorobenzene - Wikipedia

    en.wikipedia.org/wiki/2-Nitrochlorobenzene

    2-Nitrochlorobenzene is an organic compound with the formula ClC 6 H 4 NO 2. It is one of three isomeric nitrochlorobenzenes . [ 1 ] It is a yellow crystalline solid that is important as a precursor to other compounds due to its two functional groups.

  3. Chlorobenzene - Wikipedia

    en.wikipedia.org/wiki/Chlorobenzene

    Chlorobenzene can persist in soil for several months, in air for about 3.5 days, and in water for less than one day. Humans may be exposed to this agent via breathing contaminated air (primarily via occupational exposure), consuming contaminated food or water, or by coming into contact with contaminated soil (typically near hazardous waste sites).

    It is also used for bleaching textiles. [2] Halazone, or 4-((dichloroamino)sulfonyl)benzoic acid, (HOOC)(C 6 H 4) (SO 2)(NCl 2). This compound was for a while used to disinfect drinking water in field situations, but has largely been replaced in that use by sodium dichloroisocyanurate. [2] Chlorine dioxide, ClO 2. [23]

  6. Chloral - Wikipedia

    en.wikipedia.org/wiki/Chloral

    Chloral tends to form adducts with water (to give chloral hydrate) and alcohols. Aside from its tendency to hydrate, chloral is notable as a building block in the synthesis of DDT. For this purpose, chloral is treated with chlorobenzene in the presence of a catalytic amount of sulfuric acid: Cl 3 CCHO + 2 C 6 H 5 Cl → Cl 3 CCH(C 6 H 4 Cl) 2 ...

  7. Sandmeyer reaction - Wikipedia

    en.wikipedia.org/wiki/Sandmeyer_reaction

    The Sandmeyer reaction can also be used to convert aryl amines to phenols proceeding through the formation of an aryl diazonium salt. In the presence of copper catalyst, such as copper(I) oxide, and an excess of copper(II) nitrate, this reaction takes place readily at room temperature neutral water. [28]

  8. 3-Nitrochlorobenzene - Wikipedia

    en.wikipedia.org/wiki/3-Nitrochlorobenzene

    Using an acid ratio of 30/56/14, the product mix is typically 34-36% 2-nitrochlorobenzene and 63-65% 4-nitrochlorobenzene, with only about 1% 3-nitrochlorobenzene. Since the above synthetic route does not efficiently produce the 3-isomer, the route most commonly used by chemists is the chlorination of nitrobenzene.

  9. 2,4-Dinitrochlorobenzene - Wikipedia

    en.wikipedia.org/wiki/2,4-Dinitrochlorobenzene

    2,4-Dinitrochlorobenzene (DNCB) is an organic compound with the chemical formula (O 2 N) 2 C 6 H 3 Cl. It is a yellow solid that is soluble in organic solvents. It is an important intermediate for the industrial production of other compounds. [2] DNCB is produced commercially by the nitration of p-nitrochlorobenzene with a mixture of nitric and ...
