Abstract

A new technology for extracting bromine from waste hydrobromic acid belongs to the pharmaceutical and chemical field. Hydrobromic acid is widely used in the pharmaceutical and chemical industry, so a large amount of waste hydrobromic acid is directly and indirectly discharged to the environment, bromide ions in the waste hydrobromic acid cannot be processed by present sewage processing systems, and a waste hydrobromic acid solution must be preprocessed, thereby the technology is utilized to substantially change unfavorable factors brought by the processing of the waste hydrobromic acid with chlorine to substantially mitigate the sewage processing cost and reduce the wastes of large amounts of resources. The chlorine is a severely-toxic dangerous chemical, death can be caused by high-density chlorine poisoning, and the use of the chlorine is clearly forbidden in China. The new technology for extracting the bromine from the waste hydrobromic acid enables the waste hydrobromic acid to be preprocessed, and is a best sewage processing method.

Description

Useless Hydrogen bromide extracts the bromine new technology
Technical field: present technique belongs to the medication chemistry industry, and Hydrogen bromide is the aqueous solution of bromize hydrogen gas, colourless or little yellow transparent liquid, and content 47.5% is a kind of strong acid, and tool is strong, and reductibility, skin exposure can cause burns.Being widely used in the medication chemistry industry, is the Essential Chemistry article.But the useless hydrobromic acid solution of big volume low-concentration is directly or indirectly entered environment after the doctorization industry is used, and existing Sewage treatment systems can't be handled bromide anion problem in the useless Hydrogen bromide at all, causes the contaminated and ample resources of a large amount of environment to be wasted.
Background technology: handled useless hydrogen bromine solutions is in useless hydrobromic acid solution, to feed chlorine (cl in the past 2) displace bromine, reaction formula: cl 2(chlorine)+HBr (Hydrogen bromide) → Br 2The mode of (bromine)+Hcl (hydrochloric acid) displaces bromine, and a large amount of hydrochloric acid produces and a large amount of cl ionss remains in the aqueous solution but have, and this causes aqueous solution secondary pollution to increase the WWT difficulty again and improves cost of sewage disposal.And chlorine (cl 2) be again a kind of murther chemical, the high concentration cl gas poisoning can cause death, is that the hazardous chemical that uses is forbidden in the strict control of country, so look for a kind of more environmental protection, safer treatment process to be imminent.
Summary of the invention: utilize the hydrogen peroxide (popular name ydrogen peroxide 50) and the reaction of useless hydrobromic acid solution to restore bromine, reaction formula: H 2O 2(hydrogen peroxide)+HBr (Hydrogen bromide) → Br 2(bromine)+H 2O (water); Hydrogen peroxide is the water white transparency thick liquid, sterilizing agent, SYNTHETIC OPTICAL WHITNER and the sanitas done commonly used in the industry.Bromine is a raw material of making inorganic or organic bromide, as: Sodium Bromide, Potassium Bromide etc. also are the main raw materials of making the hydrogen bromine.Their reaction final products are bromine and water; Bromine will be recovered to come back in the production and use, and remaining water will enter into the Sewage treatment systems processing, and this will reduce cost of sewage disposal greatly; Reducing the unfavorable factor of extracting bromine with the chlorine method greatly, is the good method that one action two gets.
Embodiment: use the Hydrogen bromide that to give up in the enterprise to collect at Hydrogen bromide, set up a whole set of production unit, comprise retort, condensing surface and bromine scoop.Useless Hydrogen bromide sucting reaction jar, heat, slowly splash into hydrogen peroxide when being heated to boiling.Hydrogen peroxide at high temperature reacts with useless Hydrogen bromide rapidly; A large amount of bromine gases steam from pyrosol, enter into the bromine scoop through the liquid condensed bromine, and reaction finishes and stops to drip; The aqueous solution is disposed to Sewage treatment systems in the cooling tank, and bromine is delivered to second stage employ in the production.
