Uses
2,2,3,3-Tetrafluoro-1-propanol, is used as an essential fluorinated fine chemical, the main application of TFP is as a dye solvent in CD-R(W) and DVD-R(W) industry. It is also used in making textile treatment agent and pharmaceuticals. This chemical is an ideal replacement for Freon 22 detergent.
General Description
2,2,3,3-Tetrafluoro-1-propanol (TFP) is extensively used as the solvent. Mineralization and defluoridation of TFP by UV oxidation in a novel three-phase fluidized bed reactor was reported. Desorption of activated carbon loaded with TFP by supercritical carbon dioxide in a rotating packed bed was investigated.
Purification Methods
Tetrafluoro-1-propanol (450mL) is added to a solution of 2.25g of NaHSO3 in 90mL of water, shaken vigorously and set aside for 24hours. The fraction distilling at or above 99o is refluxed for 4hours with 5-6g of KOH and rapidly distilled, followed by a final fractional distillation. [Kosower & Wu J Am Chem Soc 83 3142 1961.] Alternatively, shake the alcohol with alumina for 24hours, dry it overnight with anhydrous K2CO3 and distil it, taking the middle fraction (b 107-108o).
