루비듐 브롬화물 C화학적 특성, 용도, 생산
개요
Rubidium bromide (RbBr) is a hygroscopic material, which is generally similar to the other rubidium halides.Rubidium bromide is the bromide of rubidium. It has a NaCl crystal structure, with a lattice constant of 685 picometres.
There are several methods for synthesising rubidium bromide. One involves reacting rubidium hydroxide with hydrobromic acid:
RbOH + HBr → RbBr + H2O
Another method is to neutralize rubidium carbonate with hydrobromic acid:
Rb2CO3 + 2 HBr → 2 RbBr + H2O + CO2
Rubidium metal would react directly with bromine to form RbBr, but this is not a sensible production method, since rubidium metal is substantially more expensive than the carbonate or hydroxide; moreover, the reaction would be explosive.
화학적 성질
white crystalline powder용도
Rubidium bromide is used in infrared optics.Purification Methods
The bromide is a white crystalline powder which crystallises from H2O (solubility: 50% in cold and 67% in boiling H2O to give a neutral solution). It also crystallises from near-boiling water (0.5mL/g) by cooling to 0o.루비듐 브롬화물 준비 용품 및 원자재
