摘要： The present invention provides a catalyst for polyester production capable of producing a polyester with high catalytic activity, a process for producing a polyester using the catalyst and a polyester produced thereby. The catalyst comprises a solid titanium compound obtained by dehydro-drying a hydrolyzate obtained by hydrolysis of a titanium halide and which has a molar ratio (OH/Ti) of a hydroxyl group (OH) to titanium (Ti) exceeding 0.09 and less than 4. In the process, the polyester is obtained by polycondensing an aromatic dicarboxylic acid, or an ester-forming derivative thereof, and an aliphatic diol, or ester-forming derivative thereof, in the presence of the catalyst. The resulting polyester has excellent transparency and tint, a titanium content of 1 to 100 ppm, a magnesium content of 1 to 200 ppm and a magnesium to titanium weight ratio of not less than 0.01.

摘要： A water treatment method sufficiently decomposes low-degradable organic substances while suppressing production of bromate ions and consumption of hydrogen peroxide. A water treatment method for purifying water using radicals includes injecting an electron-donating substance selected from the group consisting of saccharides, amino acids, lipids, humic acid, and mixtures thereof into water. The radicals are preferably produced using ozone and hydrogen peroxide in combination. Further, the electron-donating substance is preferably injected into the water in a concentration of 0.1 μmol/L to 30 μmol/L.
