Nitric anhydride
WebbPhosphorus (III) oxide is a white crystalline solid that smells like garlic and has a poisonous vapour. It oxidizes slowly in air and inflames when heated to 70 °C (158 °F), forming P 4 O 10. It is the acid anhydride of phosphorous acid, H 3 PO 3, that is produced as P 4 O 6 dissolves slowly in cold water. WebbThe main results were obtained in this study. (1) A reliable detection method for atmospheric PAN, PPN, and CCl4 was developed by using HP-5890 gas chromatograph coupled with electron capture detector, six-port valve, and DB-1 capillary column. The optimized GC conditions were as follows: the GC oven and detrctor temperatures were …
