Web27 mei 2024 · Phosphorus triiodide (PI 3) is an unstable red solid which reacts violently with water. It is a common misconception that PI 3 is too unstable to be stored; it is, in fact, commercially available. It is widely used in organic chemistry for converting alcohols to alkyl iodides. It is also a powerful reducing agent. http://www.ukmaterialsafetydatasheets.co.uk/msds/generic_msds_red_phosphorus.pdf
