实验过程

Ascorbic acid (5 g, 28.4 mmol) was dissolved in 20 ml of water, followed by slow addition of cesium carbonate (4.63 g, 14.2 mmol) in the temperature range of 0 to 5° C. 40 ml of isopropyl alcohol was slowly added to the reaction mixture when the generation of carbon dioxide completely stopped. After standing for several hours, the precipitate was filtered and washed with isopropyl alcohol, and dried to give 8.4 g of the cesium ascorbate as a white solid (yield 95%).
