Reaktionsschritte
Process: Apply crystallized citric acid, then heat to 60° C. and wet with 36 ml of gluconic acid delta-lactone solution (10 parts of gluconic acid delta-lactone to 5 parts of water); apply malic acid, then allow sodium bicarbonate I to react to give monosodium citrate and malate and then allow sodium bicarbonate II, calcium carbonate and potassium bicarbonate to undergo partial reaction (partial conversion to the citrate). Then cover the surface with citric acid powder. Finally allow sodium carbonate to undergo partial reaction, and dry in vacuo. This effervescent base is mixed with 500 parts of aspirin and with corresponding additives.
