WebPhosphine ( IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane ( P2H4 ). WebTrioctylphosphine is an organophosphorus compound with the formula P (C 8 H 17) 3 sometimes abbreviated TOP. [1] It is usually encountered as a syrup. The compound is colorless. Reactions [ edit] Trioctylphosphine reacts with oxygen to form trioctylphosphine oxide. For this reason it is usually handled with air-free techniques .
