| 20120095270 | NONCRYSTALLINE FORM OF FLUORENE DERIVATIVE AND PROCESS FOR PREPARATION THEREOF - An object of the present invention is to provide (i) a novel non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene, which non-crystalline form maintains quality at a certain level, and is excellent as a polymer material, and (ii) a method of preparing the non-crystalline form. According to the present invention, molten 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene in a liquid form is cooled and therefore is solidified. With the method, it is possible to provide a novel non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene which has a small risk that powder dust of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene might cause explosion or a health problem. Further, the non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene can be adjusted arbitrarily in particle diameter by, for example, pulverizing the non-crystalline form in accordance with equipment or usage. In other words, the non-crystalline form of 9,9-bis(4-(2-hydroxyethoxy)phenyl)fluorene is advantageous in handleability industrially. | 04-19-2012 |
