| 稳定性 | 此水合物在170℃加热仍不分解。在175～200℃之间，释出水合水，同时放出少量H2S。在无CO2的干燥空气中，KHS·12H2O可长期存放；但若有CO2，则迅速分解并释出H2S。在湿O2气氛下，易被氧化成K2S2O3。在空气中放置，变成黄色，放出H2S并转变成多硫化物。 |

Section 1: Product Identification Chemical Name:Potassium hydrogen sulfide, anhydrous, min. 95% CAS Registry Number:1310-61-8 Formula:HKS EINECS Number:215-182-9 Chemical Family:metal chalcogenides Synonym:potassium bisulfide, potassium mercaptan
Section 2: Composition and Information on Ingredients IngredientCAS NumberPercentACGIH (TWA)OSHA (PEL) Title compound1310-61-8100%no datano data Section 3: Hazards Identification May form highly toxic and flammable hydrogen sulfide gas on exposure to acids or stomach fluids. Corrosive Emergency Overview: to skin, eyes and mucous membranes. Possible risk of irreversible effects. Primary Routes of Exposure:Ingestion, inhalation, skin, eyes Eye Contact:Dust causes burns to the eyes. Contact with skin can produce serious caustic burns with painful inflammation and possible destruction of Skin Contact: tissue. Inhalation of dust can lead to chemical burns to the respiratory tract. Hydrogen sulfide, if formed, is poisonous. Inhalation: Ingestion:Gastric juices causes release of toxic hydrogen sulfide. Hydrogen sulfide gas may cause painful conjunctivitis, headache, nausea, dizziness, pulmonary edema and Acute Health Affects: possible death. Corrosive to skin, eyes and respiratory tract. Possible risk of irreversible effects. Chronic Health Affects:No information available on long-term chronic effects NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce Ingestion: vomiting only if directed by medical personnel. SECTION 5: Fire Fighting Measures Flash Point:not applicable Autoignition Temperature:no data Explosion Limits:no data Extinguishing Medium:carbon dioxide or dry powder If this product is involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure Special Fire Fighting Procedures: self-contained breathing apparatus and full protective clothing. Hazardous Combustion andIf involved in a fire, this material may emit irritating fumes of hydrogen sulfide and sulfur dioxide. Decomposion Products: Dust may form explosive mixtures with air. Contact with acids gives off hydrogen sulfide; a toxic and Unusual Fire or Explosion Hazards: flammable gas. SECTION 6: Accidental Release Measures In the case of a spill, the fine powder should be covered with dry sodium carbonate or dolomite in order to Spill and Leak Procedures: reduce the formation of dust. Sweep up the mixture. SECTION 7: Handling and Storage Store in a tightly sealed container. Exposure to the atmosphere may lead to release of toxic hydrogen sulfide Handling and Storage: gas. Empty containers may retain product residues that evolve toxic gases. SECTION 8: Exposure Controls and Personal Protection Eye Protection:Wear safety glasses and face shield or goggles when handling this chemical substance in the laboratory. Skin Protection:Wear appropriate chemical resistant rubber gloves and protective clothing. Ventilation:Handle the material in an efficient fume hood. If ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Respirator: Protection Program to be in compliance with 29 CFR 1910.134. Ventilation:Handle the material in an efficient fume hood. Additional Protection:No additional protection required. SECTION 9: Physical and Chemical Properties Color and Form:white to off-white pwdr. Molecular Weight:72.18 Melting Point:no data Boiling Point:no data Vapor Pressure:no data Specific Gravity:no data Odor:odor of rotten eggs Solubility in Water:very soluble SECTION 10: Stability and Reactivity Stability:slow decomposition in air, hygroscopic Hazardous Polymerization:no hazardous polymerization contact with air, and mineral acids. Reaction with mineral acids can lead to formation of toxic hydrogen sulfide Conditions to Avoid: fumes. Incompatibility:oxidizing agents, mineral acids, halogens and carbon Decomposition Products:hydrogen sulfide, sulfur dioxide, potassium sulfate, and potassium hydroxide SECTION 11: Toxicological Information RTECS Data:No information available in the RTECS files Carcinogenic Effects:no data Mutagenic Effects:no data Tetratogenic Effects:no data SECTION 12: Ecological Information Ecological Information:No information available SECTION 13: Disposal Considerations Disposal:Dispose of according to local, state and federal regulations SECTION 14: Transportation Shipping Name (CFR):Self-heating solid, Inorganic, N.O.S. Hazard Class (CFR):4.2 Additional Hazard Class (CFR):NA Packaging Group (CFR):II UN ID Number (CFR):UN# 3190 Shipping Name (IATA):Self-heating solid, Inorganic, N.O.S.
