Potassium carbonate synthesis

7synthesis methods
The name potash comes fromthe traditional method of making potassium carbonate, which has been performed sinceancient times. Preparing potassium carbonate involved burning wood or other plant material,leaching the ashes in a wooden barrel covered on its bottom with straw, and then evaporatingor boiling away the water in the leachate in clay or iron pots to recover potassium and sodiumalkalis.

Yield:-

Reaction Conditions:

with carbon dioxide;triethylamine in tetrahydrofuran at 20; for 2 h;

Steps:

9 Production of potassium carbonate and complex from potassium Production of potassium carbonate and complex from potassium

To the potassium lactate filtrate obtained in Example 4, experiment 1, above, was addedtriethylamine (20 mL) and THF (30 mL). Carbon dioxide gas was bubbled through themixture for 2 hours with stirring. The resulting suspension was filtered and the solid was dried at 50°C overnight to afford 1.01 g solid which effervesced on treatment with hydrochloric acid (assumed to be potassium carbonate).
