Combined hydrogen bromide generating device and technology

Abstract

The invention belongs to the fields of pharmaceutical chemical and production technology. To solve the problems, such as short life, insufficient strength, leaking liability of harmful gas, and low bearing pressure, of a hydrogen bromide generating device in the prior art, provided is a combined hydrogen bromide generating device and technology. The device comprises a combustor, the bottom of which is connected to one side of a condenser; the other side of the condenser is connected to an adsorption bed; and the end part of the adsorption bed is connected to a hydrogen bromide storage tank. The top part of the combustor is provided with a quartz glass nozzle; the cavity of the combustor is externally provided with a steel jacket; and cooling water passes through the steel jacket. An ignition source of the combustor is an electronic igniter. An adsorbent of the adsorption bed is active carbon. The hydrogen bromide storage tank is provided with an explosion-proof membrane. The inner cavity of the combustor, the condenser, and the hydrogen bromide storage tank are made from glass enamel. The device is bromine-resistant or hydrogen bromide-resistant, is beneficial for carrying out a reaction and meeting requirements of subsequent metering storage of hydrogen bromide gas, and satisfies the requirement of industrial mass production. The service life of the device is better prolonged; the technical condition is easy to control; and the product yield and purity are improved.

Description

technical field [0001] The invention belongs to the technical field of medicine, chemical industry and production, and in particular relates to a combined hydrogen bromide generating device and a process thereof. Background technique [0002] Hydrobromic acid is the basic raw material for the manufacture of various inorganic bromides and certain alkyl bromides (methyl bromide, ethyl bromide). In medicine, it is used to synthesize sedatives, anesthetics and other medical supplies. In industry, hydrobromic acid is a good solvent for some metal minerals, a separating agent for alkoxy and phenoxypicrin compounds, and oxidation of alicyclic hydrocarbons and chain hydrocarbons to ketones. , acid or peroxide catalyst; as an alkylation catalyst in the petroleum industry; hydrobromic acid is also used in the synthesis of dyes and fragrances. In addition, it is also used as a raw material for analytical reagents and flame retardants. [0003] There are many production methods of hyd...
