Phosphorus triiodide is commonly used in the laboratory for the conversion of primary or secondary alcohols to alkyl iodides. EC Number 236-647-2. If infant formula has been chosen to partially or wholly replace breastmilk, the iodine content in the infant formula will affect the dietary iodine intake of the infant. The required hydriodic acid in this variation of the hydriodic acid/red phosphorus method is produced by the reaction of iodine in water with red phosphorus. According to one analysis of data on healthy U.S. adults using NHANES III data collected in 1988–1994, high phosphorus intakes (1,000 mg/day or more) were associated with increased rates of all-cause and cardiovascular mortality in adults through 2006 . Iodine (\(\ce{I2}\)) Some elements exist naturally as molecules. Answer Save. Heating to higher temperatures reconverted the red modification to the yellow one.
