Provided is a production process by which a novel alicyclic oxetane
compound which has an oxetane ring, has excellent light transmission in
the near ultraviolet region, and is useful as a cationically
polymerizable monomer can be easily obtained. The production process
which is for obtaining an alicyclic oxetane compound includes subjecting
an aromatic oxetane compound to nuclear hydrogenation in high-pressure
hydrogen in the presence of a hydrogenation catalyst. For example, when
4,4'-bis[(3-ethyloxetan-3-yl)methoxymethyl]biphenyl is used as the
aromatic oxetane compound,
4,4'-bis[(3-ethyloxetan-3-yl)methoxymethyl]bicyclohexyl is obtained as
the alicyclic oxetane compound.
