'''Nitrosylsvavelsyra''' är en [[anhydrid]] av [[svavelsyra]] och [[salpetersyra]]. Den har [[kemisk formel|formeln]] HSO<sub>4</sub>NO.<br />
<br />
==Framställning==<br />
Nitrosylsvavelsyra bildas när [[svaveldioxid]] (SO<sub>2</sub>) löses i koncentrerad salpetersyra (HNO<sub>3</sub>), vilket är det som händer när svavelsyra tillverkas enligt [[blykammarprocessen]].<br />
:<math>\rm SO_2 + HNO_3 \rightarrow HSO_4NO</math><br />
<br />
Det kan också framställas genom att blanda svavelsyra och salpetersyra.<br />
:<math>\rm H_2SO_4 + HNO_3 \rightarrow HSO_4NO + H_2O</math><br />
<br />
==Användning==<br />
Nitrosylsvavelsyra används som en källa till NO<sup>+</sup>-joner som till exempel kan användas för att konvertera [[amin]]er till [[diazonium]]-[[salter]], till exempel [[anilin]] till [[bensendiazonium]].<br />
:<math>\rm C_6H_5NH_2 + NO^+ \rightarrow C_6H_5N_2^+ + H_2O</math><br />
