应用领域
概述柠檬酸钠又称枸橼钠、枸橼酸钠、柠檬酸三钠,分子式Na3C6H5O7·2H2O,分子量294.1,是一种无色晶体或白色结晶性粉末产品，无臭、味咸、凉 。在150℃失去结晶水，更热则分解。在湿空气中微有潮解性，在热空气中有风化性，易溶于水及甘油，不溶于乙醇，难溶于醇类及其他有机溶 剂。柠檬酸钠无毒性、具有pH调节性能及良好的稳定性，因此可用于食品工业。柠檬酸钠用作食品添加剂，需求量最大，主要用作调味剂、缓 冲剂、乳化剂、膨胀剂、稳定剂和防腐剂等；另外，柠檬酸钠同柠檬酸配伍，用作各种果酱、果冻、果汁、饮料、冷饮、奶制品和糕点等的胶 凝剂、营养增补剂及风味剂。
用途作Ph调节剂和乳化增强剂，用于果酱、糖果、果冻和冰淇淋等；与柠檬酸配合有缓和酸味的作用；还有络合金属离子的作用。我国规定可用于各类食品，按生产需要适量使用
用途用作食品添加剂，电镀工业用络合剂、缓冲剂，医药工业用于制造抗血凝药，轻工业用作洗涤剂的助剂等
用途用作食品添加剂，电镀工业用作络合剂、缓冲剂，医药工业用于制造抗血凝药，轻工业用作洗涤剂的助剂等
用途用作色谱分析试剂和细菌培养基的制备，还用于制药工业
用途该品用于食品加工的调味、稳定剂，无毒电镀工业作缓冲剂和副络合剂，医药工业用作抗凝血剂、化痰药和利尿药，还用于酿造、注射液、报影药品等。
制备方法
生产方法由柠檬酸经氢氧化钠或碳酸氢钠中和而得。将碳酸氢钠在搅拌加热下溶解于水，加入柠檬酸，继续升温至85-90℃，调整pH为6.8。加活性炭脱色，趁热过滤。滤液减压浓缩，冷却后析出结晶。过滤、洗涤、干燥，得柠檬酸钠。
生产方法先将碳酸氢钠搅拌溶解于热水，然后于85～90℃下，加入柠檬酸中和至Ph值6.8。再加入活性炭脱色，并趁热过滤。滤液经减压浓缩、冷却结晶、离心分离、洗涤、干燥得柠檬酸钠。C6H8O7+3NaHCO3→C6H5Na3O7·2H2O+3CO2↑+H2O
