[(3,5,6-Trichlor-2-pyridyl)oxy]essigsure, Verbindung mit Triethylamin (1:1) Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
Triclopyr triethylamine salt was first reported in 1975 by Byrd
and coworkers. Triclopyr, also known by the trade name Garlon,
is an herbicide used extensively in the control of woody
plants and broadleaf weeds.

Environmental Fate
Triclopyr TEA is a grayish white granular solid. It is miscible
in water, slightly soluble in toluene and ethyl acetate, and
practically insoluble in hexane. The Henry’s law constant is
1.15 × 10
-14 atm-m3 mol
-1; octanol/water partition coefficient
is <5 (1.23).
Air
Volatilization of triclopyr TEA occurs slightly due to its lower
vapor pressure. Low Henry’s law constant indicates little escaping tendency from an aqueous solution. Triclopyr is not
found in air with the exception of spray drift and dust from
pesticide application.
Water
Triclopyr TEA is degraded by photodegradation in water. It is
highly water soluble and dissociates to the weak acid triclopyr
acid and triethanolamine. Triethanolamine rapidly degrades to
CO2 by aerobic microbial processes (half-life 14–18 days).
However, triethanolamine does not degrade under anaerobic
aquatic conditions (half-life >2 years). Triclopyr acid further
dissociates to triclopyr anion, which is the predominant moiety
in the environment. The photolysis of triclopyr acid in aqueous
media is rapid and the half-life is approximately 1 day in water.
The major photolyzed products of triclopyr acid observed were
5-chloro-3,6-dihydroxy-2-pyridinoloxyacetic acid and oxamic
acid in water.
Soil
The major route of dissipation in soil is through microbial
degradation. Moisture favors the microbial growth, which in
turn increases microbial activity. The triclopyr acid is degraded
primarily by microbes with half-lives of 8–18 days to intermediate
compounds 3,5,6-trichloro-2-pyridinol (TCP) and
3,5,6-trichloro-2-methoxypyridine (TMP), and CO2. Triclopyr,
TMP, and TCP have lower soil mobility due to which there
might be limited leaching.
There is no evidence on bioaccumulation of triclopyr in fish
or aquatic nontarget microorganisms.
