Abstract

The thermal decomposition of alkali metal succinates i.e. M 2(CH 2COO) 2· xH 2O (M = Li, Na, K, NH 4) has been studied up to 823 K by employing simultaneous non-isothermal techniques (DTG, DTA and TG). The final thermolysis products are the corresponding metal carbonates as characterized by chemical analysis and IR spectroscopy. A comparison of the decomposition temperatures leads to the stability order Li > Na > K > NH 4. The results are also compared with analogous oxalates.
