| titleOfInvention | Manufacturing method for high purity, high yield 1,1,2,2,9,9,10,10-octafluoro [2.2] paracyclophane (AF4) using cooling recrystallization separation technique |
| abstract | The present invention utilizes the difference in the solubility of AF4 according to the type of solvent, and uses a cooling recrystallization separation technology capable of removing impurities through cooling recrystallization during the manufacturing process of AF4, a monomer of parylene HT. ,1,2,2,9,9,10,10-octafluoro[2.2]paracyclophane (AF4). The present invention is a method for purifying AF4 (1,1,2,2,9,9,10,10-octafluoro[2.2]paracyclophane), comprising: dissolving AF4 and impurities in a solvent; And cooling the solvent, wherein a difference in solubility (g/100g solvent) of AF4 in the solvent according to a temperature change in the cooling step is 70% or more. |
