葡萄糖酸钠Sodium gluconate

葡萄糖酸钠是葡萄糖酸的钠盐，由葡萄糖发酵产生。它是一种白色到棕褐色，颗粒状到细晶状粉末，极易溶于水。无腐蚀性、无毒且易于生物降解（2天后98%），葡萄糖酸钠作为螯合剂，水处理，减水剂，缓凝剂，混凝土添加剂，玻璃瓶清洗剂，食品添加剂，越来越受到重视。葡萄糖酸钠的突出特性是其优异的螯合能力，特别是在碱性和浓碱性溶液中。它与钙、铁、铜、铝和其他重金属形成稳定的螯合物，在这方面，它超过了所有其他螯合剂，如EDTA、NTA和相关化合物。葡萄糖酸钠的水溶液即使在高温下也能抵抗氧化和还原。然而，它很容易被生物降解（2天后降解98%），因此不会产生废水问题。葡萄糖酸钠也是一种高效的缓凝剂，也是混凝土、砂浆和石膏的良好增塑剂/减水剂。最后但同样重要的是，它具有抑制食品苦味的特性。

Sodium gluconate is the sodium salt of gluconic acid, produced by fermentation of glucose. It is a white to tan, granular to fine, crystalline powder,very soluble in water. Non corrosive, non-toxic and readily biodegradable (98 % after 2 days), sodium gluconate is more and more appreciated as chelating agent. The outstanding property of sodium gluconate is its excellent chelating power, especially in alkaline and concentrated alkaline solutions. It forms stable chelates with calcium, iron, copper, aluminium and other heavy metals, and in this respect, it surpasses all other chelating agents, such as EDTA, NTA and related compounds. Aqueous solutions of sodium gluconate are resistant to oxidation and reduction, even at high temperatures. However, it is easily degraded biologically (98 % after 2 days), and thus presents no wastewater problem. Sodium gluconate is also a highly efficient set retarder and a good plasticiser / water reducer for concrete, mortar and gypsum. And last but not least, it has the property to inhibit bitterness in foodstuffs.
