We focuse on the decomposition, and on the technology of
recycling for chemical substances that may have negative impact on the
environment, while they have high functionality and therefore important
not only in industry but also in our lives.
Specifically, we are developing new reaction technologies (subcritical
and supercritical water reactions and photochemical reactions) to decompose
organofluorine compounds (including fluoropolymers as well) that consist
of strong carbon-fluorine bonds, enabling it to be used as a resource again.
Organofluorine compounds and fluoropolymers have unique characters such
as high thermal and chemical stability, high surface-active effect, and high light
transparency. These chemicals, although, are used in industry as functional
materials, waste treatment techniques for them are not well established.
These chemicals may be decomposed by incineration. This, however,
requires high temperatures and HF gas is formed, which can seriously damage the incinerator.
Therefore, development of decomposition techniques that work under mild
condition is desired. The method should produce F- ions, because such method would allow the recycling of a fluorine resource.
