Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. Calcium hypochlorite is mainly applied in fields such as disinfection, water treatment, food processing, paper and textile bleaching, and chemical synthesis, and can also be used for the preparation of cleaners and disinfectants; Calcium hypochlorite is modelled as a pure substance; when modelling this substance the user needs to add a solvent of their choice in the model; the dataset contains the main raw and auxiliary materials, energy and atmospheric emissions of the production process, and infrastructure such as the manufacture of production equipment and the construction of plant buildings 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 charging, chlorination, separation and drying. Sodium chloride is a by-product of this production process.
Activity Description
The production activities of this product include feeding, chlorination, separation, drying and other processes.
Process Description
Calcium hypochlorite has the chemical formula Ca(OCl)2 and CAS number 7778-54-3. It is generally a white or off-white powder with a pronounced pungent chlorine odor and readily absorbs moisture and forms lumps. It dissolves readily in water to form a strongly alkaline solution and is insoluble in organic solvents such as ethanol and diethyl ether. It is chemically reactive and has strong oxidizing and bleaching properties. In water it gradually forms hypochlorous acid, which further decomposes and releases oxygen and hydrochloric acid, producing disinfecting and bleaching effects. Contact with acids rapidly releases chlorine gas. It is widely used to disinfect drinking water, swimming pools, municipal wastewater, environments, and surfaces and to bleach fabrics and pulp. Other applications include degrading reducing contaminants and removing odors in water treatment, disinfecting food-processing equipment, pipelines, and workshops, use as an oxidizing agent in chemical synthesis, and water disinfection and disease prevention in aquaculture.

Technology comment
The sodium process is an advanced technology for producing calcium hypochlorite. Compared with the traditional calcium process, the product offers higher effective chlorine content and better stability. Its market share in the domestic high-end calcium hypochlorite market is gradually increasing, making it an important direction for replacing the traditional process. Calcium hypochlorite is modeled as being produced by the sodium process, involving the chemical reaction equations: Cl2 + 2NaOH = NaClO + NaCl + H2O, and 2NaClO + Ca(OH)2 → Ca(ClO)2↓ + 2NaOH.
