Abstract Trichloroacetates of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y were prepared and their composition determined. Decomposition of these compounds was studied by thermogravimetry in air and in nitrogen atmosphere followed by chemical analysis. In all cases the anhydrous chloride is first formed. This remains stable in nitrogen, while in air the oxychloride and subsequently the oxide are formed at higher temperatures.
