Abstract

The thermal decomposition of La(C₃H₇CO₂)₃·xH₂O (x≈0.82) was studied in argon during heating at 5K/min. After the loss of bound H₂O, the anhydrous butyrate presents at 135°C a phase transition to a mesophase, which turns to an isotropic liquid at 180°C. The decomposition of the anhydrous butyrate is associated to a solidification process. The final decomposition to La₂O₃ takes place via two intermediate products: La₂O(C₃H₇CO₂)₄ and La₂O₂CO₃ with release of CO₂ and the symmetrical ketone C₃H₇COC₃H₇.
