In a mixture of benzene and isopropanol,ĭichlone degraded to the minor products: 2-chloro-3-hydroxy-1,4-naphthoquinone, 2-Ĭhloro-3-phenoxy-1,4-naphthoquinone, 2,3-dichloro-4-hydroxy-1-keto-2-phenyl-1,2-ĭihydronaphthalene and isopropyl-1-chloro-2,3-dioxo-1-indanecarboxylate (Ide et al.,ġ979). Further irradiation in the presence of oxygen yielded phthalicĪcid and phthalic anhydride as the major products. Presence of oxygen, 2-chloro-1,4-naphthoquinone, 1,4-naphthoquinone and 1,4-naphthalenediol Using UV light produced a number of dehalogenated compounds. Irradiation of dichlone in a variety of organic solvents (benzene, isopropanol, ethanol) The UV absorption band for dichlone is 330 nm (Gore et al., 1971).

Flammability and Explosibilityįungicide: Not currently registered in the U.S. Special Hazards of Combustion Products: Highly toxic fumes are imminent. INHALATION: Irritation to mucous membrane. They react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. Ketones are incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. Ketones react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. The amount of heat may be sufficient to start a fire in the unreacted portion of the ketone. Ketones are reactive with many acids and bases liberating heat and flammable gases (e.g., H2).

Air & Water ReactionsĢ,3-Dichloro-1,4-naphthoquinone is a halogenated ketone. Can easily penetrate the soil and contaminate groundwater and nearby streams. Immediate steps should be taken to limit its spread to the environment. The primary hazard is the threat to the environment. Can cause illness by inhalation, skin absorption and/or ingestion.

General DescriptionĢ,3-Dichloro-1,4-naphthoquinone is a yellow crystalline solid dissolved in a water-emulsifiable liquid carrier. Usesįungicide used on fruits, field crops and vegetables Usesįungicide for agriculture and textiles herbicide. Also used as an important catalyst to produce 3,3-dichlorobenzene. Use in textiles, as organic catalyst, as chemical intermediate, as additive in dye binders.
