Abstract: Provided is a method for producing n-propyl acetate capable of suppressing the deterioration of a hydrogenation catalyst to such an extent that the catalyst can be industrially used, for example, in the case where n-propyl acetate is produced by performing a hydrogenation reaction in the presence of the hydrogenation catalyst using, as a raw material liquid, a liquid containing allyl acetate or the like which has been produced from propylene, oxygen and acetic acid and obtained using a purification process such as distillation. In such a method for producing n-propyl acetate, the concentration of a formyl group-containing compound (such as acrolein, propionaldehyde or 2-methylcrotonaldehyde) and the concentration of an acryloyloxy group-containing compound (such as acrylic acid or allyl acrylate) in the raw material liquid are respectively set to 100 ppm by mass or less. As a result, the deterioration of the hydrogenation catalyst can be suppressed to such an extent that the catalyst can be industrially used.

Abstract: A high emission intensity group-III nitride semiconductor light-emitting device obtained by eliminating crystal lattice mismatch with substrate crystal and using a gallium nitride phosphide-based light emitting structure having excellent crystallinity. A gallium nitride phosphide-based multilayer light-emitting structure is formed on a substrate via a boron-phosphide (BP)-based buffer layer. The boron phosphide-based buffer layer is preferably grown at a low temperature and rendered amorphous so as to eliminate the lattice mismatch with the substrate crystal. After the amorphous buffer layer is formed, it is gradually converted into a crystalline layer to fabricate a light-emitting device while keeping the lattice match with the gallium nitride phosphide-based light-emitting part.
