Изооктил (2,4-дихлорфенокси) ацетат химические свойства, назначение, производство
Химические свойства
2,4-Dichlorophenoxyacetic acid is a white
to yellow crystalline powder with a slight phenolic odor.
Использование
2,4-D isooctyl ester is a useful biochemical for proteomics research.
Общее описание
White crystals in commerce, a brown or dark brown liquid.
Реакции воздуха и воды
Insoluble in water.
Профиль реактивности
Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Пожароопасность
2,4-D isooctyl ester is combustible.
Возможный контакт
2,4-Dichlorophenoxyacetic acid,
was introduced as a plant growth-regulator in 1942. It
is registered in the United States as a herbicide for control
of broadleaf plants and as a plant growth-regulator. Thus,
workers engaged in manufacture, formulation or application
are affected, as may be citizens in areas of application. The
Vietnam war era defoliant, Agent Orange, was a mixture of
2,4-D and 2,4,5-T.
Перевозки
UN3345 Phenoxyacetic acid derivative pesticide,
solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous
materials. A DOT regulated marine pollutant.
Несовместимости
A weak acid, incompatible with bases.
Decomposes in sunlight or heat, forming hydrogen chloride
and phosgene. Contact with strong oxidizers may cause fire
and explosions.
Утилизация отходов
Incineration of phenoxys is
effective in 1 second @ 982
C, using a straight combustion
process or @ 482℃
using catalytic combustion. Over 99%
decomposition was reported when small amounts of 2,4-D
were burned in a polyethylene bag. See “References”
for additional detail. In accordance with 40CFR165, follow
(31); recommendations for the disposal of pesticides and
pesticide containers. Must be disposed properly by follow-
ing (100) Package (2) label directions or by contacting
your local or federal environmental control agency, or by
contacting your regional EPA office. Consult with environ-
mental regulatory agencies for guidance on acceptable
disposal practices. Generators of waste containing this
contaminant (≥100 kg/mo) must conform with EPA regu-
lations governing storage, transportation, treatment, and
waste disposal.
