Abstract

Cerium(III) chloride reacted with sodium nitrite—potassium nitrite eutectic, initially in the solid state but more rapidly on melting, to form cerium(IV) oxide, while lanthanum(III) chloride, praseodymium(III) chloride and europium(III) chloride reacted, very largely in the liquid state, undergoing anion exchange and a partial Lux—Flood acid—base reaction to form oxide nitrites (LnONO₂) initially. At higher temperatures the latter two chlorides reacted further to form the oxides (Pr₆O₁₁ and Eu₂O₃, respectively). In lithium nitrite—potassium nitrite eutectic, the course of the reactions was similar but the temperatures at which reaction commenced were lower.
