Manufacture
2,4-D is a member of the phenoxy family of herbicides, which include:
- 2,4,5-Trichlorophenoxyacetic acid (2,4,5-T)
- 2-Methyl-4-chlorophenoxyacetic acid (MCPA)
- 2-(2-Methyl-4-chlorophenoxy)propionic acids (mecoprop, MCPP)
- 2-(2,4-Dichlorophenoxy)propionic acid (dichlorprop, 2,4-DP)
- (2,4-Dichlorophenoxy)butyric acid (2,4-DB)
2,4-D is manufactured from chloroacetic acid and 2,4-dichlorophenol, which is itself produced by chlorination of phenol. Alternatively, it may be produced by the chlorination of phenoxyacetic acid. The production processes creates several contaminants including isomers, monochlorophenol, and other polychlorophenols and their acids.
