摘要：
The thermal decomposition in air of benzene-1,3-dioxyacetates of Y, La and lanthanides from CeIII to LuIII was studied. During heating, the hydrated complexes Ln2[C6H4(OCH2-COO)2 ]3·n H2O (n = 7-12) lose water of crystallisation in one (La-Nd, Eu, Lu) or two steps (Y, Ce, Sm, Gd-Yb), then decompose directly to oxides (Ce) or with intermediate formation of oxycarbonates: Ln2O2CO3 (La, Pr, Sm-Ho), Ln2O3·0.5CO2 (Y, Er-Lu) or two types of oxycarbonates (Nd). © 1990.
