| titleOfInvention | Method for removing unsaturated impurities in 1,1,2,3,3, 3-hexafluoropropyl hydrofluoroether crude product |
| abstract | The invention provides a method for removing unsaturated impurities in a 1,1,2,3,3, 3-hexafluoropropyl hydrofluoroether crude product, which can separate 1,1,2,3,3, 3-hexafluoropropyl hydrofluoroether from 1,1,2,3, 3-pentafluoropropylene hydrofluoroether or 1,2,3, 3-pentafluoropropylene hydrofluoroether impurities well by using a physical method of column chromatography to prepare a 1,1,2,3,3, 3-hexafluoropropyl hydrofluoroether product with the purity of more than 99%. The method of the invention does not use dangerous chemistry, greatly improves the operation safety, does not generate wastes harmful to the environment, can regenerate and reuse the adsorbent silica gel column, reduces the cost and saves the resources. |
