其他信息

类别:氧化剂
图谱信息:硝酸钾(7757-79-1)红外图谱(IR1)
上游原料:硝酸 --> 碳酸钾 --> 氢氧化钾 --> 氯化钠 --> 氯化铵 --> 碳酸氢铵 --> 氯化钾 --> 硝酸钠 --> 硝酸铵
方法二:将硝酸钠和氯化钾溶于水进行复分解反应，有沉淀生成，过滤后蒸发浓缩；当溶液相对密度达1.45～1.49(45～48°Bé)、温度达119℃时，首先析出氯化钠；经真空过滤滤去氯化钠，滤液用10％～1
下游产品:间硝基苯甲醛 --> 复合肥 --> 6-氨基-2-N-BOC-1,2,3,4-四氢-异喹啉 --> 钨酸钠 --> 4-乙烯基吡啶 --> 8-氨基异喹啉 --> 1-氟-4-(三氟甲基硫代)苯 --> 3,8-二氨基-5-甲基-6-苯基溴化菲啶盐 --> NPK复合肥 --> 硫酸庆大霉素 --> 8-溴异喹啉 --> 2-溴-5-甲基磺酰硝基苯 --> 3-硝基-4-甲基吡啶 --> 三氟羧草醚 --> 3-甲基-2,4-二氯-5-硝基苯甲酸 --> 2,4-二羟基-6-甲基-5-硝基嘧啶 --> 碘酸钙 --> 氨合成催化剂 --> 7-氨基异喹啉 --> 4-氨基-3-吡啶甲醛 --> 4-硝基喹啉-N-氧化物 --> 7-甲基腺嘌呤 --> 5-氯-1-甲基-4-硝基咪唑 --> 过碘酸钾 --> 1,2-二羟基蒽醌 --> 亚硝酸钾 --> 3-氨基-2-溴-4,6-二甲基吡啶 --> 6-氨基吲哚 --> 6-硝基吲哚 --> 2,3,5-三甲基-2,5-环己二烯-1,4-二酮 --> 3-氨基-4-硝基三氟甲苯 --> 异丙基磺酰氯 --> 氨合成铁系催化剂 --> 2,4-二甲基-5-氨基吡啶 --> 2,6-二硝基苯胺 --> 碘化银 --> NCY型乙苯脱氢催化剂
用途六:硝酸钾也是我国允许使用的发色剂。它在肉制品中由于细菌作用而还原成亚硝酸钾而起护色和抑菌的作用。我国规定可用于肉类制品，最大使用量0.5g/kg，残留量不得超过0.03g/kg。
灭火剂:雾状水
外观性质:无色透明斜方或三方晶系颗粒或白色粉末。
含量分析:精确称取试样约0.4g(预经105℃干燥4h)，溶入盛于500ml圆底烧瓶中的300ml水中。加德瓦达合金粉3g和40%氢氧化钠溶液15ml后，将防溅球和冷凝器与烧瓶连接。在受器中放0.1mol/L硫酸50ml，静置2h，蒸馏，至馏出液250ml，用0.1mol/L氢氧化钠滴定过量硫酸，用3滴甲基红-亚甲蓝试液(TS-150)作为指示剂。同时进行空白试验，并作必要修正。每毫升0.1mol/L硫酸相当于硝酸钾(KNO 3 )10.11mg。

急性毒性:口服- 大鼠 LD50: 3750 毫克/ 公斤
硝酸钾价格(试剂级):更新日期产品编号产品名称包装价格 2011/08/23 10017218 硝酸钾（*）（易制爆） 500g 15.5元 2011/08/23 10017228 硝酸钾（*）（易制爆） 500g 14元 2011/08/23 K6002901 原子吸收钾标准溶液1000mg／L 100ml 138.0
防护措施:在生产中吸入硝酸钾粉尘，经过数月之后则出现鼻粘膜溃疡。饮用含有50～100mg/L硝酸钾的水，血中变性血红蛋白明显升高。对皮肤有刺激作用。生产人员在工作时要戴口罩，以防止吸入硝酸钾粉尘，保护呼吸器官；要穿工作服，戴乳胶手套等劳保用品，以保护皮肤。
所属类别三:无机化工产品: 无机盐: Cl硝酸盐
使用限量:FAO/WHO(1984，mg/kg)：熟洋火腿、熟猪前腿肉，500；一般干酪50(单用或与硝酸钠合用量)。 GB 2760-2001：肉制品0.50g/kg。
用途三:发色剂；抗微生物剂；防腐剂；护色剂。
