Specification
The Potassium bromide, with the CAS registry number 7758-02-3,is also known as Potassium tert-butylate; Potassium tert-butoxide; KtB. It belongs to the product categories of Bromide salt of potassium.Its EINECS number is 231-830-3. This chemical's molecular formula is KBr and molecular weight is 119.00. What's more,Its systematic name is Potassium bromide.It is a odourless white or colourless crystalline solid which is stable,incompatible with strong oxidizing agents,strong acids,bromine trifluoride and bromine trichloride.It is widely used as an anticonvulsant and a sedative in the late 19th and early 20th centuries. Potassium bromide is presently used as a veterinary drug, as an antiepileptic medication for dogs and cats.
Production of Potassium bromide:
A traditional method for the manufacture of potassium bromide is the reaction of potassium carbonate with a bromide of iron, Fe3Br8, made by treating scrap iron under water with excess bromine:
4 K2CO3 + Fe3Br8 → 8 KBr + Fe3O4 + 4 CO2
