'''碘乙烷'''是一种无色、易燃的有机化合物。其化学式为C<sub>2</sub>H<sub>5</sub>I，可由[[碘]]、[[磷]]及[[乙醇]]加热制得。<ref name="merck">Merck Index of Chemicals and Drugs, 9th ed., monograph 3753</ref>与空气接触，尤其是在光照条件下，碘乙烷会分解，产生的碘溶于碘乙烷而使碘乙烷略显黄色。

碘乙烷可以通过[[红磷]]、无水[[乙醇]]和碘的反应制备，该反应中，[[三碘化磷]]不稳定，需原位生成。<ref>Csámpai,A;Láng,E;Majer,Zs;Orosz,Gy;Rábai,J;Ruff,F;Schlosser,G;Szabó,D;Vass,E: Szerves Kémiai Praktikum page: 274, Eötvös kiadó 2012 {{ISBN|978-963-312-129-0}}</ref>反应温度需要控制。
