Description and Uses
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.
3,4-Dichloroaniline is used as an intermediate for pesticides and dyes.
