Molecular formula :
CAS :
nature : colorless or pale yellow liquid smoke. Liberals 57% and 52% 2 concentration. New products for the colorless, but exposure to sunlight and air quickly turns yellow or brown. 2.85g/cm3 density (-4.7 ° C). -50.8 ° C melting point. Boiling point -35.38 ° C Yes acidity, but also strong reducing agent, and many formed metal iodide. Periodate iodine and hydrogen formed three iodide ions, so a lot of iodine solution. , One of the air and see that the decomposition of sunlight, it is appropriate to bring a brown sealed containers, stored in the shades. Erosion can skin and mucous membranes. By iodine and red phosphorus increase response distilled water, distillation, collecting 126 ~ 127 ° C distillate, or hydrogen iodide absorption of water in the system. Hydrogen can also be used with dry iodine vapor in the platinum catalyst and the high temperature reaction, generating hydrogen iodide, for absorbing materials, could be used in the suspension of iodine containing distilled water to the reactor, blowing hydrogen sulfide gas, hydrogen generation and solid sulfur periodate, filtration, distillation, purification or obtained. For reductant. Used in the manufacture of inorganic iodide, medicines, disinfectants.
