Sicherheit und Schutzausrüstung
Fire FightingFires involving this compound can be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Nonfire Spill Response
SMALL SPILLS AND LEAKAGE: You should dampen the solid spill material with acetone, then transfer the dampened material to a suitable container. Use absorbent paper dampened with acetone to pick up any remaining material. Seal your contaminated clothing and the adsorbent paper in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with acetone followed by washing with a strong soap and water solution. Do not reenter the contaminate area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Personal Protective Equipment (PPE)
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)
Toxikologische Informationen
Adverse EffectsOccupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

Anwendungen
Verwenden1,8-Dinitronaphthalene (cas# 602-38-0) is a compound useful in organic synthesis.
Darstellung
synthetischeSeparation of dinitronaphthalene: Crude mixtures of dinitronaphthalene (5 g, from Table-3 run 8) was placed together with 50 mL acetone in a 100 mL flask, stirred and heated to reflux. The suspension was refluxing for 2 h and then cooled to 30 oC by stirred and filtered quickly. The precipitate was recrystallized by acetone and 1,5-dinitronaphthalene as light yellow crystals (1.725 g) was got. Then the filter liquor was concentrated to one-thirds of original volume, filtered, the precipitate was recrystallized by toluene and 1,8- dinitronaphthalene as light yellow crystals (1.987 g) was got. 1, 5-Dinitronaphthalene: m.p. 215-216 oC, 1H NMR (400 MHz, CDCl3): δ = 7.84 (t, 2H), 8.33 (d, 2H), 8.81 (d, 2H). 1, 8-Dinitronaphthalene: m.p. 172-173 oC, 1H NMR (400 MHz, CDCl3): δ = 7.98 (t, 2H), 8.51 (dd, 4H).
