Uses and applications
What the substance is used for, by industry and function
Selective herbicide for control of a variety of weeds.
Eptam is used in every region of the United States in the agricultural production of a wide variety of food crops. Eptam is used on non-food use sites such as citrus nursery stock, non-bearing fruit orchards, evergreens, deciduous trees, scrubs, pine seeding nurseries, and ornamentals. Eptam is also used at residential/public sites such as parks, flower gardens, turf grasses, and golf course sand traps.
Control of annual and perennial grasses and some broad-leaved weeds in crops.
Use classes: Herbicides.
Functional uses
- Biocide
How it is made
Reaction of ethyl mercaptan with phosgene to produce ethyl chlorothioformate, followed by reaction of this with di-n-propylamine
It may be synthesized either by the reaction of ethanethiol & dipropylcarbamoyl chloride, formed from dipropylamine & phosgene, or by the reaction of dipropylamine with ethyl chlorothioformate.
