Preparation method of basic zinc chloride
2017
The invention discloses a preparation method of basic zinc chloride. The basic zinc chloride is prepared from zinc chloride and ammonium bicarbonate. The preparation method of the basic zinc chloride is reasonable in design, the purity of the synthesized basic zinc chloride is larger than 98%, the zinc content is larger than 58%, and the preparation method has the advantages that the basic zinc chloride is good in fluidity, non-hygroscopic, non-caking, easy to absorb and the like. Ammonium chloride in mother liquor can be recovered, rinse water can be used for preparation of sodium hypochlorite, zero emission and environment-friendliness can be realized in enterprises, the production cost is low, solid particles are uniform, and the basic zinc chloride can be used for replacing zinc oxide to be used for production of a feed-grade basic zinc chloride additive.
