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. Hydrobromic acid is mainly used to produce inorganic bromides, remove alkoxides and phenoxides, replace hydroxyl groups in substitution reactions, and add to alkenes; it can also catalyse mineral extraction and certain alkylation reactions; hydrobromic acid is modelled as a pure substance, i.e. hydrogen bromide, and 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, 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 hydrogen bromide synthesis and hydrobromic acid absorption.
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.
