Source sentences:
text: Hydrogen bromide prepared by the above methods can be contaminated with Br 2 , which can be removed by passing the gas through a solution of phenol at room temperature in tetrachloromethane or other suitable solvent (producing 2,4,6-tribromophenol and generating more HBr in the process) or through copper turnings or copper gauze at high temperature.
