WebPhosphine is a chemical compound which is part of the group of organophosphorus compounds. Chemical formula of Phosphine is PH₃. Phosphine has a rotten fish odour. Phosphine can be found in tissues, blood, saliva, and other body organs. Phosphine is prepared by the reaction of calcium phosphide with water and dilutesHydrochloric acid. WebPhosphine (PH₃) is a colorless, flammable, and explosive gas at room temperature that smells like garlic or decaying fish. Exposure to phosphine may cause, nausea, vomiting, stomach pain, diarrhea, thirst, muscle pain, difficulty breathing, and fluid in the lungs. Higher exposures and long-term exposure may cause serious harm.
WebPhosphonates are esters of phosphonic acid and have the general formula RP (=O) (OR') 2. Phosphonates have many technical applications, a well-known member being glyphosate, better known as Roundup. With the formula (HO) 2 P (O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides. WebThe Phosphine Predictor, developed in collaboration with Prof. Matthew S.
