| Hazard Information | Back Directory | [Chemical Properties]
clear liquid with an aromatic odour | [Uses]
1,2-Dibromotetrafluoroethane is used as a high-efficiency fire extinguishing agent, coolant, high-temperature gas lubricant, and also as a heat transfer medium. | [Purification Methods]
Wash it with water, then with weak alkali. Dry with CaCl2 or H2SO4 and distil it. [Locke et al. J Am Chem Soc 56 1726 1934.] Also purify it by gas chromatography on a silicone DC-200 column. |
