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. Methyl chloride is widely used in fields such as organic synthesis, refrigerants, solvents, methylating agents and pesticide intermediates. Methyl chloride 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, waste and atmospheric emissions of the production process, in which the preliminary treatment of wastewater in the auxiliary units and the waste gas treatment process are included within the dataset boundary, 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 raw material mixing, reactor reaction, cooling, separation and rectification.
Activity Description
The production activities of this product include raw material mixing, reactor reaction, cooling, separation, distillation and other processes.
Process Description
Chloromethane (also known as methyl chloride) has the chemical formula CH3Cl and CAS number 74-87-3. At normal temperature and pressure, it is a colorless, readily liquefied gas with a faint ether-like odor and is denser than air. It is slightly soluble in water and soluble in organic solvents such as ethanol, diethyl ether, and acetone. It is flammable and can form explosive mixtures with air. Industrially, chloromethane is mainly used as a methylating agent and an organic-synthesis feedstock, especially in the manufacture of silicones. It is also used to produce methylcellulose, quaternary ammonium compounds, and certain pesticides.

Technology comment
The methanol hydrochlorination method is the leading technology for methyl chloride production, accounting for approximately 90% of the domestic methyl chloride market. This data set represents the mainstream technology: hydrogen chloride and methanol undergo a substitution reaction in the presence of a catalyst (such as an acidic catalyst, aluminum chloride or zinc chloride) to form methyl chloride. Reaction equation: HCl + CH3OH → CH3Cl + H2O. 1. Mixing of raw materials: Dry hydrogen chloride gas and purified methanol are thoroughly mixed in a mixer. 2. Reactor: The mixed raw materials enter the reactor and react in the presence of the catalyst under appropriate reaction conditions. 3. Cooling: The gas mixture generated by the reaction is cooled by a cooler to facilitate the subsequent separation process. 4. Separation: The cooled mixture enters a separator to separate methyl chloride and water. 5. Distillation: The separated methyl chloride gas is further purified through a distillation tower to obtain high-purity methyl chloride products.
