Japanese glass producer Asahi Glass has succeeded in the development of a direct fluorination technology that drastically simplifies production process compared with existing technologies. Through an independently developed reaction control methodology, fluorinated compounds can be obtained without having to proceed via a multi-stage reaction process. Moreover, production of fluorinated compounds which to date have been impossible to manufacture can now be achieved. Asahi Glass“ new fluorination technology is called “PERFECT.” The process entails blowing fluorine gas onto the target material, whereby it is directly fluorinated to produce the fluorinated product. As fluorine gas is highly reactive, it is difficult to handle, and therefore, if multi-step reactions using other compounds are not used, the target material cannot be obtained. Toward commercialization, Asahi Glass has already installed a pilot plant in its Chiba factory. In existing areas where cost reductions are aimed for, the company intends to initially convert production of transparent resins used in semiconductors, optical fibres, and display materials, and ion exchange resins, to the new process. In addition, the company will advance application of the new process in new areas such as resins for next-generation photoresists, pellicle resins, and fuel cell applications. At Asahi Glass, plans call for development of the fluorine business centred on high added value areas.
