硝酸铬(III) 九水合物制备

1.蔗糖还原法将铬酸酐和硝酸加入带有搅拌器的反应器中，在搅拌下缓慢加入蔗糖进行还原反应，生成硝酸铬，过滤，把滤液送去蒸发浓缩、冷却结晶、离心分离，制得硝酸铬成品。其反应方程式如下：
2.将紫色的CrCl3·6H2O溶于稍过量的热硝酸中，放在装有氢氧化钠的真空干燥器中，让其冷却结晶。析出Cr(NO3)3·9H2O晶体。抽滤，并用滤纸吸去附着的硝酸。 3.现制得Cr(OH)3,用热水洗过后，以尽可能少的4mol/L冷硝酸溶解。放在带塞的瓶中。放置数日，析出结晶。 4. 将氢氧化铬溶解于密度为1.40的稍过量的试剂硝酸中，反应可得硝酸铬：过滤后，滤液于50～60℃下蒸发至相对密度为1.4时，添加少量试剂硝酸，和九水合硝酸铬晶种，0℃以下静置，结晶，待结晶完全后，过滤、甩干，空气中干燥至硝酸味消失，即得分析纯硝酸铬（九水）。母液回收利用。
