Industrial grade Zinc acetate dihydrate 5970-45-6

What is zinc acetate dihydrate?

Zinc acetate dihydrate, with the chemical formula C4H10O6Zn , is a white to off-white crystalline powder with a slight characteristic acetic acid odor. As an organic acid salt of zinc, it consists of divalent zinc ions coordinated with two acetate ions, carrying two molecules of water of crystallization to form a stable crystal structure.

Its core physicochemical parameters are as follows:

The main difference between industrial-grade zinc acetate dihydrate and food-grade and pharmaceutical-grade products lies in their purity standards and impurity control requirements . Industrial-grade products typically have a purity between 95% and 98% , with relatively relaxed restrictions on heavy metals and microorganisms, but they must still meet relevant industrial application specifications. Their production process generally involves the reaction of zinc oxide or metallic zinc with acetic acid.

ZnO+2CH3COOH+H2O→Zn(CH3COO)2⋅2H2OZnO+2CH3COOH+H2O→Zn(CH3COO)2⋅2H2O

Industrial-grade products are typically supplied in large packaging forms such as 25kg bags and ton bags , which are suitable for mass industrial production.
