摘要:

The exchange reaction between Ba14CO3and some alkali metal carbonates has been studied in detail in a trial to find out the appropriate experimental conditions for preparing14C-labelled oxalates. It has been found that the best results could be achieved by heating the reaction mixture at 390°C for 6 hours. The used Ba14CO3could be quantitatively recovered and recycled again in another exchange process.
