세스퀴황화 인 C화학적 특성, 용도, 생산
화학적 성질
Yellowish-green crystals; long rhombic needles; melts at 172°C (341°F); boils at 407–408°C (764–766°F);density 2.03 at 20°C (68 °F); soluble in carbon disulfide, benzene, and toluene, reacts with water.Stable in the air. In the absence of O2 and moisture, remains stable above 700°C. Decomposed by water at elevated temperatures, evolving H3S. Soluble in CS3 and benzene. These solutions become turbid in air almost immediately and gradually deposit a copious, yellowish-white precipitate
용도
Phosphorus sesquisulfide is used in making safety matches.일반 설명
A yellow crystalline solid. Easily ignited by friction. Forms sulfur dioxide and phosphorus pentaoxide during combustion. Reacts with water to form phosphoric acid, a corrosive material. Used to make matches and in the manufacture of other chemicals.공기와 물의 반응
Highly flammable.Slowly decomposed by water to form phosphoric acid and toxic hydrogen sulfide gas (H2S). May ignite on contact with water or moist air.반응 프로필
PHOSPHORUS SESQUISULFIDE is a reducing agent.건강위험
Phosphorus sesquisulfide exhibited low to moderate acute oral toxicity in animals. An oral dose lethal to rabbits was reported to be 100 mg/kg (NIOSH 1986). Because of its low vapor pressure, any health hazard due to inhalation of this compound in the work place should be very low. There is no report on its acute inhalation toxicity. Its vapors may produce irritation of respiratory passage. Skin contact may cause mild irritation. It produces toxic sulfur dioxide on burning.화재위험
Produce flammable and toxic gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Containers may explode when heated. Runoff may create fire or explosion hazard.Safety Profile
Poison by ingestion. Flammable by spontaneous ignition. When heated to decomposition it emits very toxic fumes of POx and SOx. See also SULFIDES and PHOSPHORUS.Synthesis
Phosphorus trisulfide can be synthesized either by Stock's method (I), which involves fusing red P and S and carefully purifying the crude product by recrystallization from CS3, followed by a second recrystallization from benzene, or according to German patent 309,618 (F. C. Frary), which uses white P in a high-melting inert solvent (II).4 P + 3 S = P4S3
Purification Methods
Extract P4S3with CS2, filter it and evaporate it to dryness. Alternatively place it in H2O, and pass steam through it for an hour. The H2O is then removed, the solid is dried, and recrystallised from CS2 [Rogers & Gross J Am Chem Soc 74 5294 1952].폐기물 처리
An alkaline solution is treated with laundry bleach, allowed to stand overnight, neutralized, and washed down the drain with plenty of water.세스퀴황화 인 준비 용품 및 원자재
