Abstract: A new lignin degradation product, a method for producing the same, and methods for producing a saccharide raw material and a monosaccharide raw material are provided. The method for producing the new lignin degradation product includes: (a first step) mixing 100 parts by mass of a powder, obtained by pulverizing a lignocellulosic raw material and defatting the resulting powder with an organic solvent, with aqueous hydrogen peroxide in an amount of 20 to 400 parts by mass in terms of hydrogen peroxide and heating the mixture for 5 to 120 minutes at a pressure of 0.1 to 1.5 MPa and a temperature of 80 to 200° C. while irradiating the mixture with microwaves; (a second step) separating insoluble matter from the aqueous hydrogen peroxide; (a third step) extracting the insoluble matter with a solvent to produce an extract; and (a fourth step) distilling the solvent away from the extract to yield a solubilized lignin as a residue.

Abstract: 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.
