Dichloroisocyanuric acid, solid is a white crystalline solid with an odor of chlorine. The material itself is noncombustible but if contaminated with a combustible material ignition can result. It will accelerate the burning of combustible materials. Contact with ammonium compounds or hydrated salts can cause a very vigorous chemical reaction. It may vigorously react with small quantities of water releasing chlorine gas. Prolonged exposure to fire or heat of the material may result in the vigorous decomposition of the material and the rupturing of its containers. Material containing less than 39 percent available chlorine will undergo reactions as described above though it may be longer to initiate and the resulting reaction may not be as vigorous. It is used as a dry bleach in household cleaning compounds and swimming pool disinfectants.
颜色/状态:

溶解度:
In water, 227 g/L at 25 °C

分解:
Decomposes exothermically at 464 °F (240 °C). Anhydrous material has a significantly lower decomposition temp.
Both s-triazine-2,4,6(1H,3H,5H)-trione, 1,3,5-trichloro- and s-triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt are unstable in the body (particularly the stomach) because the available chlorine is rapidly reduced. Cyanuric acid (or its monosodium salt) is the degradation product from both products.
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Organic acids and related compounds/
Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist respirations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Activated charcoal is not effective ... . Do not attempt to neutralize because of exothermic reaction. Cover skin burns with dry, sterile dressings after decontamination ... . /Organic acids and related compounds/
Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Early intubation, at the first sign of upper airway obstruction, may be necessary. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Consider administering a beta agonist such as albuterol for severe bronchospasm ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Organic acids and related compounds/
/LABORATORY ANIMALS: Acute Exposure/ No irritation on the intact skin of /albino/ rabbits was observed after application of sodium (potassium) dichloroisocyanurate in the form of dry powder for 24 hr. /Sodium dichloroisocyanurate/
