THERMAL DECOMPOSITION OF THE LIGHT RARE EARTH OXALATES
The thermal decomposition of the light rare earth oxalates was studied in vacuum in the temperature range 340-440 deg C. The behavior of the whole group (with the exception of europium oxalate) was analogous to that of lanthanum oxalate. The relative order of stability, as well as that of the intermediate normal and basic carbonatcs, is: Gd > Sm > Nd > La > Pr > Ce. The carbon monoxide, initially formed by the decomposition of the oxalates, underwent disproportionation. The degree of disproportionation was highest in the case of cerous oxalate (72%), and lowest in the case of gadolinium oxalate (58%), decreasing in reverse of the order of stability, with lanthanum and praseodymium changing places.
