'''Fosfortrioxid''' är en [[kemisk förening]] av [[fosfor]] och [[syre]] och är en [[anhydrid]] av [[fosforsyrlighet]]. Dess [[kemisk formel|kemiska formel]] är P<sub>2</sub>O<sub>3</sub>, men brukar oftast skrivas P<sub>4</sub>O<sub>6</sub> eftersom molekylerna bildar slutna, polycyliska [[dimer]]er vars struktur liknar [[adamantan]] (se bild).<br />
<br />
==Framställning==<br />
Fosfortrioxid framställs genom förbränning av vit fosfor vid låg temperatur och låg syretillförsel.<br />
:<math>\rm P_4 + 3\ O_2 \rightarrow P_4O_6</math><br />
<br />
==Egenskaper==<br />
Fosfortrioxid löser sig långsamt i kallt vatten till fosforsyrlighet (H<sub>3</sub>PO<sub>3</sub>).<br />
:<math>\rm P_4O_6(s) + 6\ H_2O(l) \rightarrow 4\ H_3PO_3(aq)</math><br />
<br />
I varmt vatten däremot blir reaktionen våldsam och bildar [[fosforsyra]] (H<sub>3</sub>PO<sub>4</sub>) och den giftiga gasen [[fosfin]] (PH<sub>3</sub>).<br />
:<math>\rm P_4O_6(s) + 6\ H_2O(l) \rightarrow PH_3(g) + H_3PO_4(aq)</math><br />
<br />
Fosfortrioxid reagerar med [[saltsyra]] (HCl) och bildar [[fosfortriklorid]] (PCl<sub>3</sub>).<br />
:<math>\rm P_4O_6 + 6\ HCl \rightarrow 2\ H_3PO_3 + 2\ PCl_3</math><br />
