Phosphorus pentasulfide

Mfumo wa Masi:PS5

Uzito wa Masi: 191.3

Phosphorus pentasulfide, is a nonmetallic inorganic compound . It is a yellow to greenish-yellow crystalline mass with an odor similar to hydrogen sulfide. It is a dangerous fire risk and ignites by friction or in contact with water. Boiling point is 995°F (535°C) and ignition temperature is 287°F (141°C). It decomposes upon contact with water or moist air, liberating toxic and flammable hydrogen-sulfide gas. Specific gravity is 2.09, so it is heavier than water. It is toxic by inhalation, with a TLV of 1 mg/m3 of air. The four-digit UN identification number is 1340. The NFPA 704 designation is health 2, flammability 1, and reactivity 2. Primary uses are in insecticides, safety matches, ignition compounds, and sulfonation. Phosphorus pentasulfide is a greenish-gray to yellow, crystalline solid with an odor of rotten eggs. The Odor Threshold is 0.005 ppm.

Katika utengenezaji wa livsmedelstillsatser mafuta lube na dawa. utengenezaji wa viberiti vya usalama, Viunga vya kuwasha, na kwa ajili ya kuanzisha salfa katika Misombo ya kikaboni. Fosforasi pentasulfide hutumiwa katika utengenezaji wa viungio vya vilainishi, dawa za kuua wadudu, mechi za usalama, na mawakala wa kuelea. Phosphorus pentasulfide (sulfidi ya fosforasi, P2S5) ni dawa ya kuua wadudu. Pia ni nyongeza kwa mafuta na sehemu ya mechi za usalama.
