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 .
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.
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 ...
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).
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.
R-dichlorprop (dichlorprop-p). Dichlorprop possesses a single asymmetric carbon and is therefore a chiral molecule, however only the R-isomer is active as an herbicide.When dichlorprop was first marketed in the 1960s, it was sold as racemic mixture of stereoisomers, but since then advances in asymmetric synthesis have made possible the production of the enantiopure compound.
Benzotrichloride is a poorly water-soluble, clear to yellowish liquid with a penetrating odor. It hydrolyzes rapidly to benzoic acid and hydrochloric acid with a half life of about 2.4 minutes, thus making the compound unstable in the presence of water. [2]
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 ...
