氯化铬制备

1.碳酸铬法将重铬酸钠溶液加入带搅拌器的衬铅或搪玻璃反应器中，在搅拌下缓慢加入硫酸进行酸化，然后加入糖蜜还原剂进行还原反应，生成硫酸铬，过滤，把硫酸铬与纯碱进行反应，生成碳酸铬，过滤，用水洗涤后，再与盐酸进行反应，生成三氯化铬。经浓缩、放出冷却固化、粉碎，制得三氯化铬成品。其反应方程式如下：

方法２．用相对密度为1.19的盐酸溶解氢氧化铬糊状物，盐酸的量以糊状物中每100g三氧化二铬用350ml盐酸计：

溶液静置后，抽滤，滤液在水浴上蒸发至原体积的1/3，然后倒入用冰冷却的容器中，通入干燥的氯化氢气体，至溶液饱和且十分粘稠，并析出结晶。静置混合物，冰冷却使结晶完全，结晶经抽滤后在30～40℃下干燥，即得成品。
