| titleOfInvention | Solid acid catalyst for production of polyester, process for production of the catalyst, and process for production of polyester using the catalyst |
| abstract | The present invention relates to a solid acid catalyst for the production of polyester which enables the production of a metal-free polyester resin containing no residual catalyst, exhibits favorable utility efficiency in the production, exhibits extremely high selectivity for the polyesterification reaction with the amount of by-products being below the limit of detection, and is able to be isolated, recovered and reused. In other words, the present invention relates to a solid acid catalyst for the production of polyester, obtained by supporting a metal oxide (B) on a support (A) formed from a metal oxide, wherein said support (A) formed from a metal oxide is a zirconia, said metal oxide (B) is a molybdenum oxide, and a Hammett acidity function (H 0 ) for said catalyst is within a range from −3 to −9, and also relates to a process for producing the solid acid catalyst and a process for producing a polyester that uses the catalyst. |
