'''ヨウ化ベリリウム'''（Beryllium iodide）は、[[化学式]]がBeI<sub>2</sub>の[[化合物]]である。[[吸湿性]]が非常に大きく、[[水]]と激しく反応して[[ヨウ化水素酸]]を生成する。

== 反応 ==
ヨウ化ベリリウムは[[金属]][[ベリリウム]]と[[ヨウ素]]とを500 - 700℃で反応させることにより合成する。

: <chem>Be\ + I2 -> BeI2</chem>

また、ヨウ化ベリリウムは[[ベリリウムカーバイド]]とヨウ化水素を気相で反応させて合成することもできる。

: <chem>Be2C\ + 4HI -> 2BeI2\ + CH4</chem>

ヨウ化ベリリウムは他の[[ハロゲン]]と交換しやすく、[[フッ素]]と反応させると[[フッ化ベリリウム]]、[[塩素]]と反応させると[[塩化ベリリウム]]、[[臭素]]と反応させると[[臭化ベリリウム]]を生ずる。

== 危険性 ==
空気中において、[[固体]]および[[蒸気]]は[[可燃性]]である<ref name="lit"/>。
