其他信息

  • 毒性:亚硝酸钡粉尘由于呼吸或误食进入体内，会引起中毒，导致肝脏、胃、食道、脑、肺、支气管等疾患。操作人员应穿戴符合规定标准的工作服、工作鞋和其他防护用具。生产过程中要注意防尘除尘。操作室应装备送排风设备。所用设备都应密闭，生产过程应机械化和自动化。
  • RTECS号:CQ9625000
  • 生产方法:热分解法 将硝酸钡加热分解，最好在加热炉内通入一氧化氮气体，即得亚硝酸钡。 复分解法将等摩尔的亚硝酸钠与氯化钡溶液在搪瓷反应釜中发生复分解反应，其 2NaNO2+BaCl2→Ba(NO2)2+NaCl 反应完成后经蒸发、结晶、干燥，得到亚硝酸钡。 在高温下将氧化氮通人到氢氧化钡溶液或碳酸钡悬浮液中进行反应，得到亚硝酸钡。
  • MOL 文件:7787-38-4.mol
  • 用途:主要用作还原剂。添加于钢筋水泥中可作保护钢筋的防锈剂。也可作有机化学反应的重氮化剂。
  • 外观性质:白色至淡黄色结晶粉末。
