'''乙炔钠'''，又称'''碳化钠'''，化学式Na<sub>2</sub>C<sub>2</sub>，是钠形成的碳化物之一。

== 制备 ==
在 400&nbsp;°C 至600&nbsp;°C 下，[[乙炔]]（C<sub>2</sub>H<sub>2</sub>）和[[钠]]反应而成。<ref name="Carbides: Properties, Production, and Applications" />

<chem>C2H2 + 2 Na -> Na2C2 + H2</chem>

== 性质==
乙炔钠在800&nbsp;°C 下[[分解]]。与水剧烈反应，发生爆炸。<ref name="Carbides: Properties, Production, and Applications" />
:<chem>Na2C2 + 2H2O -> 2NaOH + C2H2 ^ </chem>
它的[[四氢呋喃|THF]]溶液可以用作羰基化合物的还原剂。<ref>{{cite book | last=Davies | first=Julian A. | title=Synthetic coordination chemistry : principles and practice | publisher=World Scientific | publication-place=Singapore | date=1996 | isbn=978-981-283-137-8 | oclc=842932875 |page=299}}</ref>
