摘要:
The present invention is to provide an inorganic sintered material that excels in photocatalytic activity as compared with that exhibited in the use of a photocatalyst of titanium oxide only.It is provided an inorganic sintered material comprising a photocatalyst, wherein the photocatalyst comprising a base having photocatalytic activity; and a silicon oxide film covering the base, wherein the film is substantially pore-free, and wherein the photocatalyst has a alkali metal content of not less than 1 ppm but not more than 1,000 ppm.
摘要:
N-substituted monochlorosuccinimides e.g., N-phenylmonochlorosuccinimide, can be prepared in a high yield by reacting a maleamic acid, e.g., N-phenylmaleamic acid, with phosgene in the presence of a catalyst, e.g., dimethylformamide.
