셀렌화 수소 C화학적 특성, 용도, 생산

화학적 성질

colourless gas with a very unpleasant smell

물리적 성질

Colorless gas; disagreeable odor; flammable; gas density 3.553 g/L; liquefiesat -41.25°C; liquid density 2.12 g/mL at -42°C; freezes at -65.73°C; criticaltemperature 137.85°C; critical pressure 88.0 atm; soluble in water, carbondisulfide and phosgene; pKa3.89 and 11.0 at 25°C, respectively, for the firstand second replaceable hydrogen.

용도

Preparation of metallic selenides and organoselenium compounds; in doping as mix for preparation of semiconductor materials containing controlled amounts of significant impurities.

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.

공기와 물의 반응

Highly flammable. Soluble in water.

반응 프로필

HYDROGEN SELENIDE is a colorless, flammable gas of unpleasant odor, a deadly poison by inhalation. HYDROGEN SELENIDE forms explosive mixtures with air. HYDROGEN SELENIDE reacts vigorously with strong oxidizing reagents, e.g., hydrogen peroxide, nitric acid [Sax, 9th ed., 1996, p.1843].

위험도

Dangerous fire and explosion risk; reacts violently with oxidizing materials. Toxic by inhalation, strong irritant to skin, damaging to lungs and liver.

건강위험

HYDROGEN SELENIDE 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.

화재위험

HYDROGEN SELENIDE is extremely flammable; may 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. HYDROGEN SELENIDE is dangerous and forms explosive mixtures with air. HYDROGEN SELENIDE can decompose into toxic fumes. Incompatible with acid, water, halogenated hydrocarbons, oxidizers, hydrogen peroxide, and nitric acid. HYDROGEN SELENIDE should be stored out of the direct rays of the sun. Keep away from heat and flames.
