Nature

white or pale yellow crystalline powder. There is a fragrant taste. The solubility in water is 60% at 20 °c, 85% at 50 °c, 133% at 80 °c, and 100 at 160% °c. Slightly soluble in alcohol, insoluble in ether. Heating to boiling in water will not decompose in a short period of time. The stability of the chelate with metal ions increases with the increase of pH value.

Preparation Method

in the industry, glucose-containing substances (e. G., grains) are used as raw materials, and sodium gluconate is prepared by fermentation method by first preparing gluconic acid from glucose and then neutralizing with sodium hydroxide. Gluconic acid can also be prepared from glucose by chemical oxidation or catalytic oxidation, but the yield is low and purification is difficult.

Use

sodium gluconate is a polyhydroxy acid type corrosion and scale inhibitor, which has excellent coordination ability to iron, calcium and copper plasma in aqueous solution, and many of the salts of these ions have a very good detergent effect. Not only has the function of scale inhibition, but also has the function of corrosion inhibition. It can be used for industrial circulating cooling water, water treatment in low-pressure boilers and water treatment in internal combustion engine cooling water systems. It can be combined with many corrosion inhibitors, and show synergistic effect, suitable for silicon, molybdenum, phosphorus, boron, tungsten, nitrite and some organic corrosion inhibitor series, sodium gluconate and organic carboxylic acid also have a good synergistic effect on corrosion inhibition. Is a green multi-functional water treatment chemicals. The composition of the alkaline cleaning formula can be used as a metal surface scale and rust removal, cement rapid setting of the inhibitor, textile processing aids and metal ion carriers.
