Potassium bromide Chemical Properties,Uses,Production
Description
Potassium bromide can be used as analytical reagents and developers, but also for the pharmaceutical industry.It can be used as the emulsion reagents for the filmstrip and photo film; used for formulating developer, used as a sedative in medical treatment.
In photographic materials, Potassium bromide is used in the manufacture of photographic film, developer, film thickener, toner and color photo bleach. In medication, it is used as nerve tranquilizers (tribromide). In addition, it is also used for chemical analysis reagents, the transmission of the spectra and infrared ray, for making special soap as well as being used in sculpture, lithography and so on.
It can be used for the preforming in the infrared test.
Uses
| Industry | Application | Role/benefit |
| Photography | Preparation of developing agent | Restrainer/ improves differentiation between exposed and unexposed crystals of silver halide, and thus reduces fog |
| Print developing solution | Alkaline accelerator/increases the printing density of thin negatives | |
| Optics | Infrared spectroscopy | Sample carrier/has no significant optical absorption lines in its high transmission region |
| Human medicine | Treatment of epileptic and seizure disorders | Effective component/anti-convulsant and sedative activity |
| Veterinary | Treatment of seizures in dogs, cats,etc. | Effective component/anti-convulsant and sedative activity |
| Chemical analysis | Titration determination of copper and silver | Titration agent |
| Polarographic analysis of indium, cadmium and arsenic | Analytical agent | |
| Removal of peripheral membrane proteins |
Spectrum purity
For IR detection; used for infrared sample preparation;Solubility (g/100ml)
0 ° C to 53.6 g; 10 ° C to 59.5 g; 20 ° C to 65.3 g; 30 ° C to 70.7 g; 40 ° C to 75.4 g
60 ° C to 85.5 g; 80 ° C to 94.9 g; 90 ° C to 99.2 g; 100 ° C to 104 g.
Preparation
The bromide is first reacted with scrap iron to obtain the Fe3Br8 • 16H2O, followed by reaction with the boiling potassium carbonate solution. Fe3Br8 • 16H2O + K2CO3-boiling heat-> 8KBr + Fe3O4 + 4CO2 + 16H2O, the Fe3O4 is filtered, followed by concentration to obtain potassium bromide.Urea reduction method: send the caustic potassium solution dissolved with urea caustic potassium solution sent to the reactor. Slowly add bromine at 80 ° C for reaction. The reaction is completed when the Ph value is 6-7. The reaction solution is added to the storage tank, subjecting to activated carbon decolorization. When the solution becomes clean, apply filtering, evaporation, crystallization, centrifugal separation and drying, that is the finished product of potassium bromide. Its reaction equation is:
3Br2 + 6KOH + CO (NH2) 2 → 6KBr + 5H2O + CO2 ↑ + N2 ↑
Toxicity
Avoid ingestion or inhalation; avoid eye and skin contact. Upon ingestion, head dizziness, nausea may occur. Immediately seek medical treatment; Upon inhalation, vomiting will happen, the patient should be immediately moved to place with fresh air and sent for medical treatment; if splashed into eyes, immediately rinse with a lot of fresh water for 2 0min; skin, upon being contact with potassium bromide, should also be subject to rinsing with plenty of water.Definition
ChEBI: A metal bromide salt with a K(+) counterion.Uses
manufacture of photographic papers and plates; process engraving.General Description
Odorless colorless crystals or white crystalline powder or white granular solid with a pungent bitter saline taste. Aqueous solutions are neutral (pH about 7).Air & Water Reactions
Water soluble.Reactivity Profile
Potassium bromide is not in generally strongly reactive. A weak reducing agent, incompatible with oxidizing agents. Also incompatible with salts of mercury and silver. Violent reactions occur with bromine trifluoride. May react with nitrous ether spirit, many alkaloidal salts and starch. May also react with acids . Reacts with concentrated sulfuric acid to generate fumes of hydrogen bromide.Fire Hazard
Flash point data for Potassium bromide are not available; however, Potassium bromide is probably nonflammable.Potassium bromide Preparation Products And Raw materials
