WebPhosphine (hydrogen phosphide, PH3)-air mixtures at concentrations above the LEL of 1.8% v/v (18,000 ppm) may ignite spontaneously. Ignition of high concentrations of phosphine gas (hydrogen phosphide, PH3) can product a very energetic reaction. Explosions can occur under these conditions and may cause severe personal injury. WebPhosphinates or hypophosphites are a class of phosphorus compounds conceptually based on the structure of hypophosphorous acid. IUPAC prefers the term phosphinate in all cases, however in practice hypophosphite is usually used to describe inorganic species (e.g. sodium hypophosphite ), while phosphinate typically refers to organophosphorus species. login con entity framework c#WebSep 14, 2024 · An international team of astronomers has detected phosphine on Venus, potentially signaling signs of life in the planet’s atmosphere, reports Shannon Stirone, Kenneth Chang and Dennis Overbye for The New York Times.
