| | 3,4-Dichloroaniline Usage And Synthesis |
| Description | 3,4-Dichloroaniline, 1-amino3,4- dichlorobenzene, is a gray
to dark-brown crystalline solid at room temperature. It is
used as an intermediate for pesticides and dyes
and is produced by catalytic hydrogenation of
3,4-dichloronitrobenzene with noble metal catalysts under pressure. Various types of additives
prevent dehalogenation during production and
reactors must be fabricated with special steel
alloys to inhibit corrosion. | | Chemical Properties | brown solid
 | | Uses | 3,4-Dichloroaniline is used as an intermediate for pesticides and dyes. | | Uses | 3,4-Dichloroaniline is used in the preparation of the herbicide propanil (P760840). | | Uses | 3,4-Dichloroaniline may be employed as derivatization reagent for the HPLC analysis of perfluorooctanoic acid (PFOA). | | Definition | ChEBI: A dichloroaniline having the two chloro-substituents at the 3- and 4-positions. | | Preparation | 3,4-Dichloroaniline is produced by catalytic hydrogenation of 3,4-dichloronitrobenzene with noble metal catalysts under pressure. Various types of additives prevent dehalogenation during production and reactors must be fabricated with special steel alloys to inhibit corrosion. | | General Description | Light tan to dark gray crystals or brown solid. Melting point 71-72°C. | | Air & Water Reactions | Sensitive to prolonged exposure to heat, light and air. Darkens in storage. Insoluble in water. | | Reactivity Profile | 3,4-Dichloroaniline is incompatible with oxidizing agetns, acids, acid chlorides and acid anhydrides. 3,4-Dichloroaniline can decompose at low pH. Hydrochloric acid accelerates decomposition. Reacts at temperatures above 356°F in the presence of ferric chloride . | | Fire Hazard | 3,4-Dichloroaniline is combustible. | | Metabolic pathway | The basidiomycete Filoboletus sp. TA9054
metabolizes 3,4-dichloroaniline and forms several
condensation products on solid media and in liquid
culture, and no oligomers are produced. Six
metabolites are identified as 3,3'-4,4'-
tetrachloroazobenzene, 4-(3,4-dichloroanilino)-3,3',4' -
trichloroazobenzene, 4-[(3,4-dichloroanilino)-4-(3,4-
dichloroanilino)]-3,3'4'-trichloroazobenzene, 2-(3,4-
dichloroanilino)-N-(3,4-dichlorophenyl)-4-
(chlorophenylene), 6-(3,4-dichloroanilino)-N-(3,4-
dichlorophenyl)-4-(chlorophenylene), and 3,5-bis(3,4-
dichloroanilino)-1,4-chlorobenzoquinone. | | Purification Methods | Crystallise the aniline from MeOH. [Beilstein 12 IV 1257.] |
