生产制备方法及用途展开↓

合成制备方法


二(乙醚丙酮)钴(Ⅱ)的晶体在实验室是很难制备的。该络合物非常易溶于非极性、非配体性溶剂,如苯、甲苯。而含水化合物则不溶于这些溶剂。这就使无水物从溶剂中结晶变得困难。通常将含水化合物[Co(acac)2]·2H2O[196],[Co(acac)2H2O]2在真空中加热得到天水物晶体。

    respirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering
    controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use
    respirators and components tested and approved under appropriate government standards such
    as NIOSH (US) or CEN (EU).
  Control of environmental exposure
    Prevent further leakage or spillage if safe to do so. Do not let product enter drains.
