  2. Dichlorotoluene - Wikipedia

    en.wikipedia.org/wiki/Dichlorotoluene

    The 2,6 and 3,5 isomers do not form acceptably from toluene or chlorotoluenes, so these isomers are prepared by indirect methods. For example, 2,6-dichlorotoluene can be prepared by chlorination of 4-toluenesulfonyl chloride followed by desulfonation .

  3. Chlorotoluene - Wikipedia

    en.wikipedia.org/wiki/Chlorotoluene

    A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...

  4. 2,4-Dichlorobenzoic acid - Wikipedia

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

    2,4-Dichlorobenzoic acid is an organic compound with the formula C 6 H 3 Cl 2 CO 2 H. It is one of more important of several isomers of dichlorobenzoic acid. It can be prepared by oxidation of 2,4-dichlorotoluene. [2] The coenzyme A thioester of 2,4-dichlorobenzoic acid is the substrate for 2,4-dichlorobenzoyl reductase.

  5. Toluene diisocyanate - Wikipedia

    en.wikipedia.org/wiki/Toluene_diisocyanate

    Toluene diisocyanate (TDI) is an organic compound with the formula CH 3 C 6 H 3 (NCO) 2.Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively.

  6. 2,4-Dichlorophenol - Wikipedia

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

    2,4-Dichlorophenol (2,4-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. It is a white solid that is mildly acidic (pK a = 7.9). It is produced on a large scale as a precursor to the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).

  7. Diphenyl oxalate - Wikipedia

    en.wikipedia.org/wiki/Diphenyl_oxalate

    The 2,4,6-trichlorophenol ester is a solid and thus easier to handle. [clarification needed] Furthermore, since trichlorophenolate is the better leaving group, the reaction will proceed faster, again producing brighter light, as compared to the phenol ester. The following colors can be produced by using different dyes:

  8. 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 intermediate for the industrial production of other compounds.

  9. 1,4-Dichlorobutane - Wikipedia

    en.wikipedia.org/wiki/1,4-Dichlorobutane

    1,4-Dichlorobutane is a chloroalkane with the molecular formula (CH 2 CH 2 Cl) 2. It is one of several structural isomers of dichlorobutane. They are all colorless liquids of low flammabiltity and of interest for specialized synthetic uses.
