  • 硬脂酸钡:硬脂酸钡亦称“十八酸钡”,化学式Ba(C18H35O2)2。分子量704.13。白色细微粉末。 熔点160℃,相对密度1.15。难溶于水,不溶于冷的乙醇,溶于热乙醇、苯、甲苯和其它非极性溶剂,在有机溶剂中加热溶解后经冷却变成胶状物。遇强酸分解成硬脂酸和相应的钡盐。在空气中有吸水性。制法:将硬脂酸和碳酸钡或氢氧化钡作用,或硬脂酸钠溶液与稀氯化钡溶液反应而制得。可用作防水制品,碱类唧筒的填料,也可用作机器的耐高温润滑剂、填料; 聚氯乙烯等塑料的耐光、耐热稳定剂、橡胶制品的耐高温粉模剂等。硬脂酸钡有毒,毒
  • 使用限量:FAO/WHO(1984):涂覆用葡萄糖粉、蔗糖粉及汤块等,15g/kg。 GB 2760-1996:胶姆糖胶基,GMP为限。 美国用于甜菜糖、压制糖果、大蒜盐、肉类嫩化、干糖蜜、沙拉预制粉、香辛料粉、酵母。
  • 类别:有毒物质
  • 外观性质:纯品为白色结晶粉末, 普通品是白色略带黄色的粉末物质。
  • 抗结剂:抗结剂又称抗结块剂,是用来防止颗粒或粉状食品聚集结块,保持其松散或自由流动的物质。其颗粒细微、松散多孔、吸附力强。易吸附导致形成结块的水分、油脂等,使食品保持粉末或颗粒状态。 我国许可使用的抗结剂目前有5种: 亚铁氰化钾、硅铝酸钠、磷酸三钙、二氧化硅和微晶纤维素。 抗结剂的品种不少,除了我国许可使用的5种以外,国外许可使用的还有硅酸铝、硅铝酸钙、硅酸钙、硬脂酸钙、碳酸镁、氧化镁、硬脂酸镁、磷酸镁、硅酸镁、高岭土、滑石粉和亚铁氰化钠等。它们除有抗结块作用外,有的还具有其他作用,如硅酸钙及高岭土还具有助滤作用,硬脂酸钙和硬脂酸镁有乳化作用等。而且除亚铁氰化物的ADI值有所限定以外,其余品种的安全性均很好,ADI值均无需规定,尚可根据需要予以适当发展。
  • 用途六:用作聚氯乙烯的稳定剂和润滑剂,可做无毒的食品包装、医疗器械等软质薄膜器皿。在聚乙烯、聚丙烯中作为卤素吸收剂,可以消除树脂中残留的催化剂对树脂颜色和模塑品的润滑剂,也可作酚醛、氨基等热固性塑料以及聚酯增强塑料的润滑剂的脱模剂,润滑脂的增厚剂,纺织品的防水剂和油漆的平光剂等。

  • 参考质量标准:FCC,1996 含量(CaO相当值;于基计) 9.0%~10.5% 游离脂肪酸(以硬脂酸计) ≤3.0% 重金属 ≤10mg/kg 干燥失重(105℃,2h) ≤4%
  • 可燃性危险特性:一种公害尘; 热分解辛辣刺激烟雾
  • 含量分析:准确称取试样约1.2g,加0.1mol/L盐酸,煮沸10min,或至脂肪酸层澄清,必要时可加水以保持原体积。冷却,过滤,用水彻底洗涤滤液和烧瓶,至最后的洗液对石蕊不再呈酸性。滤液用氢氧化钠试液(TS-224.)中和至石蕊呈中性。在磁力搅拌器充分搅拌下,经一50ml滴定管加入0.05mol/L的EDTA二钠液约30ml,再加氢氧化钠试液15ml和羟基萘酚蓝指示剂300mg,并继续滴定至蓝色终点。每毫升0.05mol/L的EDTA二钠液相当于CaO2.804mg。
