Description
Hydrobromic acid is mainly used for producing inorganic bromides, removing alkoxides and phenoxides, replacing hydroxyl groups in substitution reactions, and addition to alkenes; it can also catalyse mineral extraction and certain alkylation reactions; Hydrobromic acid (i.e. hydrogen bromide) 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 and atmospheric emissions of the production process, in which the preliminary treatment of wastewater in the utility/auxiliary processes and the waste-gas treatment process are included within the dataset boundary, 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 the synthesis of hydrogen bromide, hydrobromic acid absorption and other processes.
Activity Description
The production activities of this product include the synthesis of hydrogen bromide, absorption of hydrobromic acid and other processes.
Process Description
The chemical formula of hydrobromic acid is HBr, CAS number: 10035-10-6. It is an aqueous solution of hydrogen bromide, which appears as a colorless, transparent to light yellow fuming liquid. It is a strongly acidic solution, highly corrosive, and easily soluble in organic solvents. High-concentration hydrobromic acid is highly volatile and will volatilize HBr gas when exposed to air, which combines with water vapor to form white mist. Hydrobromic acid is mainly used to produce inorganic bromides, remove alkoxides and phenates, replace hydroxyl groups in substitution reactions, and add to olefins. It can also catalyze mineral extraction and certain alkylation reactions.

Technology comment
The raw material bromine is sent to the bromine preheater with a metering pump, and reacts with the hydrogen from the hydrogen buffer tank under high temperature conditions in a sealed synthesizer to generate hydrogen bromide gas, which is then absorbed with water to produce hydrobromic acid. The core reaction chemical equation of this process is: H2+Br2=2HBr.
