Description
Zinc chloride is mainly used for making dry batteries, wood preservatives, soldering fluxes, mordants and dehydrating agents in organic reactions, and is also used in fields such as batteries, hardboard, electroplating, medicine, wood preservation, pesticides and welding; Zinc chloride is modelled as a pure substance; when modelling this substance, the user is required to add a solvent of their choice in the model. The dataset includes the main raw and auxiliary materials, energy, atmospheric emissions, wastewater and solid waste of the production process, in which the wastewater and waste-gas treatment processes are included within the dataset scope, while infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources; the production activities of this product include raw material pretreatment, reaction and purification, slag discharge and filtration, the evaporation and crystallization of zinc chloride mother liquor and other processes.
Activity Description
The production activities of this product include raw material pretreatment, reaction purification, slag removal and filtration, evaporation and crystallization of zinc chloride mother liquor, etc.
Process Description
The chemical formula of zinc chloride: ZnCl2, CAS number is 7646-85-7. Appearance: white granular crystals or crystalline powder, boiling point 732℃, melting point 290℃. It has strong deliquescent property and is easily soluble in water, oxygen-containing organic solvents such as ethanol, glycerol, acetone, and ether, and nitrogen-containing solvents such as pyridine and aniline. When reacting with water, the solution will become acidic. Zinc chloride is mainly used in dry batteries, wood preservatives, welding fluxes, mordants and organic reaction dehydrating agents. It is also used in batteries, cardboard, electroplating, medicine, wood preservatives, pesticides and welding.

Technology comment
The acid leaching method is the mainstream production process for industrial-grade zinc chloride. The core of this process involves the reaction of zinc-containing raw materials (such as zinc suboxide, zinc ash, and zinc slag) with hydrochloric acid to generate a zinc chloride solution, which is then subjected to a series of purification, evaporation, and crystallization steps to obtain the solid product.
