Uses and applications

What the substance is used for, by industry and function

The active ingredient is no longer contained in any registered pesticide products ... "cancelled.".

In non-crop areas such as roadsides, railways, ditches. Also in certain established crops such as alfalfa, asparagus, flax, potatoes, rape seed, sugar beets.

For quackgrass, bermudagrass, johnsongrass, other perennial and annual grasses, cattails, rushes. Often preplant for established perennial grasses in cropland, noncropland areas, irrigation ditch banks. Translocates to the roots of most species as a growth regulator.

Use classes: Herbicides.

Functional uses

  • Biocide

How it is made

2,2-Dichloropropionic acid can be made by chlorination of propionic acid, propionaldehyde, or propanol.

Dichloropropionic acid is produced by the direct chlorination of propionic acid in the presence of catalysts. Alkali salts are prepared by contacting 2,2-dichloropropionic acid with an essentially dry alkali compound of an alkali metal in a liquid chlorinated hydrocarbon as a reaction medium, and thereafter separating in its solid phase an alkali salt of 2,2-dichloropropionic acid.
