METHOD FOR THE PRODUCTION OF A TITANIUM CONTAINING CATALYST, TITANIUM CONTAINING CATALYST, METHOD FOR THE PRODUCTION OF POLYESTER AND POLYESTER |
| 摘要 |
The present invention is directed to a method for the production of a titanium containing catalyst, wherein a titanium-(IV)-alkoxide of high purity is reacted with an alpha-hydroxy carboxylic acid. Furthermore the invention concerns a titanium containing catalyst allowing for the production of high viscosity polyesters with high thermal stability. In addition, the invention is directed to a method for the production of polyesters and polyesters themselves. |

1. A method for the production of a titanium containing catalyst, comprising reacting at least one titanium-(IV)-alkoxide of the general formula
Ti(OR)4 wherein each R is the same or different of a linear or branched alkyl with 1 to 32 carbon atoms,
with at least one alpha-hydroxy carboxylic acid, thereby forming one or more titanium alpha-hydroxy carboxylate species and an alcohol with the formula ROH, wherein the overall content of the sum of all titanium oxide species, relative to the at least one titanium-(IV)-alkoxide, Ti(OR)4 is ≦10.0 mol.-%. |
