Colorless liquid. The vapor ignites spontaneously in air.
M.p. -99°C, b.p. +51.7°C. Decomposes on rough surfaces and
in the presence of traces of acid (particularly in light) into PH3 and
amorphous, yellow "solid hydrogen phosphide," which must be considered a "mixed polymerizate." | [Definition]
A yellow liquid that can be condensed
out from phosphine in a freezing
mixture. It ignites spontaneously in air. | [Definition]
ChEBI: The simplest of the diphosphanes, consisting of two covelently linked phosphorus atoms each carrying two hydrogens. | [Definition]
diphosphine: A yellowliquid, P2H4, which is spontaneouslyflammable in air. It isobtained by hydrolysis of calciumphosphide. Many of the references tothe spontaneous flammability ofphosphine (PH3) are in fact due totraces ofP2H4 as impurities. |
