| Hazard Information | Back Directory | [General Description]
DICHLONE(117-80-6) is a yellow crystalline solid dissolved in a water-emulsifiable liquid carrier. Can cause illness by inhalation, skin absorption and/or ingestion. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Can easily penetrate the soil and contaminate groundwater and nearby streams. Used as a fungicide. | [Reactivity Profile]
DICHLONE is a halogenated ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2). The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. | [Air & Water Reactions]

Notclassified | [Agricultural Uses]
Fungicide: Not currently registered in the U.S. Not approved for
use in the EU. Dichlone is used as a fungicide for foliage
and to control blue algae in ponds, swimming pools and
lakes. As a substitute for copper and sulfur to control rot on
fruit trees, vegetables, field crops, ornamentals, resident
and commercial outdoor areas. | [Trade name]

Plant. In plants, dichlone loses both chlorine atoms and are replaced by sulphydryl
groups to give a substituted dimercapto compound (Hartley and Kidd, 1987).
Photolytic. The UV absorption band for dichlone is 330 nm (Gore et al., 1971).
Irradiation of dichlone in a variety of organic solvents (benzene, isopropanol, ethanol)
using UV light produced a number of dehalogenated compounds. In the absence or
presence of oxygen, 2-chloro-1,4-naphthoquinone, 1,4-naphthoquinone and 1,4-naphthalenediol
were produced. Further irradiation in the presence of oxygen yielded phthalic
acid and phthalic anhydride as the major products. In a mixture of benzene and isopropanol,
dichlone degraded to the minor products: 2-chloro-3-hydroxy-1,4-naphthoquinone, 2-
chloro-3-phenoxy-1,4-naphthoquinone, 2,3-dichloro-4-hydroxy-1-keto-2-phenyl-1,2-
dihydronaphthalene and isopropyl-1-chloro-2,3-dioxo-1-indanecarboxylate (Ide et al.,
1979).
Chemical/Physical. Emits toxic fumes of chlorine when heated to decomposition (Sax
and Lewis, 1987). | [Purification Methods]
Crystallise the quinone from EtOH. [Beilstein 7 IV 2426.] |
