칼륨 황화물 C화학적 특성, 용도, 생산

화학적 성질

colourless solid; turns brownish-red on

화학적 성질

Potassium sulfide is a brownish-red crystalline solid.

용도

Reagent in analytical chemistry, depilatory, medicine.

일반 설명

A red crystalline solid. Denser than water. Contact may severely irritate skin, eyes and mucous membranes. May be toxic by ingestion.

공기와 물의 반응

May spontaneously ignite with exposure to air. Deliquescent. Water soluble

반응 프로필

A reducing agent. So readily oxidized as to be pyrophoric in air [Bretherick 1979 p. 120]. POTASSIUM SULFIDE is incompatible with chloroform and nitrogen oxide.

위험도

Flammable, dangerous fire risk, may ignite spontaneously, explosive in the form of dust or pow- der.

건강위험

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

화재위험

Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.

Safety Profile

Poison by ingestion and inhalation. Emits H2S in contact with acids; steam. A flammable solid. Unstable; may explode on percussion or rapid heating. Ignites on contact with nitrogen oxide. Reacts with H2O to form KOH and KSH. When heated to decomposition it emits very toxic fumes of K2O and SOx. See also SULFIDES.

잠재적 노출

Potassium sulfide is used as a reagent in analytical chemistry; and in pharmaceutical preparations.

운송 방법

UN1382 Potassium sulfide, anhydrous or Potassium sulfide with <30% water of crystallization, Hazard Class: 4.2; Labels: 4.2-Spontaneously combustible material.

비 호환성

May explosively decompose from shock, friction, or concussion. Dust or granules may spontaneously ignite on contact with air. The aqueous solution is a strong base; reacts violently with strong acids and acid fumes. The solid material decomposes on contact with acids producing hydrogen sulfide, and oxidizers producing sulfur dioxide.
