| 화재 위험 | It is extremely flammablemay be ignited by heat, sparks, or flames. Vapors may travel to a source of ignition and flash back. Container may explode in heat of fire. It is dangerous and forms explosive mixtures with air. It can decompose into toxic fumes. Incompatible with acid, water, halogenated hydrocarbons, oxidizers, hydrogen peroxide, and nitric acid. It should be stored out of the direct rays of the sun. Keep away from heat and flames. (EPA, 1998)· These materials are extremely flammable.Extremely flammable. Gas/air mixtures are explosive. |

| 건강 유해성 | It is a hazardous compound which can cause damage to the lungs and liver. Those experiencing dermatitis, chronic bronchitis, or any form of skin allergy or respiratory tract infection are at a greater risk. (EPA, 1998)· TOXICExtremely Hazardous. |
| 유해성 요약 | Experimental animals show signs of respiratory irritation and die after 8 hour exposures of 1 mg/m3 (0.3 ppm). Pathological examination shows evidence of liver damage. Inhalation of hydrogen selenide by workers has caused eye, nose, and respiratory irritation. Pulmonary edema is a potential toxic effect. [ACGIH] Hydrogen selenide is probably the only selenium compound that might pose a health concern in the workplace. [ATSDR ToxFAQs] Possible frostbite from contact with liquid |
용도
용도
Preparation of metallic selenides and organoselenium compounds; in doping as mix for preparation of semiconductor materials containing controlled amounts of significant impurities.
제조 및 합성 방법
제조 방법
Hydrogen selenide may be synthesized directly from elements by heatingat elevated temperatures. It is prepared by heating hydrogen at 440°C witheither selenium metal in a sealed tube or with selenium vapor over pumicestone: H2 + Se → H2Se Alternatively, the compound may be prepared by treating an alkali metalselenide with hydrochloric acid during mild heating: NaSe + 2HCl → H2Se + NaCl
생산 방법
Hydrogen selenide (H2Se) may be formed by the reaction of acids or water with metal selenides or wherever nascent hydrogen is in contact with soluble selenide compounds. It has no commercial use.
