解説塩化セリウム塩化セリウム(Ⅲ)：CeCl3(246.48)．セリウム(Ⅲ)の酸化物，水酸化物，炭酸塩を塩化アンモニウムと混合して加熱すると無水物が得られる．無水物は無色の吸湿性の結晶．融点847 ℃，沸点1730 ℃．無水物のほか，一水和物，三水和物，六水和物，七水和物がある．いずれも無色の吸湿性結晶である．水，エタノールに易溶，塩酸に可溶．セリウム金属，セリウム化合物の製造，オレフィンの重合触媒などに用いられる．

使用Cerium(III) chloride is used in incandescent gas mantles, spectrography and polymerization of olefins. It acts as a Lewis acid and used in Friedel-Crafts alkylation and acylation reactions in organic synthesis. It is used as a precursor for the preparation of other cerium salts, such as cerium(III) trifluoromethanesulfonate.

使用用途塩化セリウムの使用用途としては、他のセリウム化合物の合成原料や有機合成におけるルイス酸としての利用があげられます。特にフリーデルクラフツアシル化反応にルイス酸として用いられるトリフルオロメタンスルホン酸セリウム (Ce(OTf)3)は、塩化セリウムを出発原料とする有用な化合物の1つです。また、オレフィンの重合触媒、α,β-不飽和カルボニル化合物のルーシェ還元、ケトンのアルキル化反応、グリニャール反応での添加剤などにも塩化セリウムが用いられています。

調製方法

Cerium(III) chloride is prepared by the reaction of hydrochloric acid with a cerium salt, such as cerium hydroxide or carbonate, followed by crystallization; Ce(OH)3 + 3HCl → CeCl3 + 3H2O Ce2(CO3)3 + 6HCl → 2CeCl3 + 3CO2 + 3H2O.
