| titleOfInvention | A kind of preparation method and application of titanium-based composite catalyst for environment-friendly polyester |
| abstract | The invention relates to the field of polyester synthesis, and discloses a preparation method and application of an environment-friendly titanium-based composite catalyst for polyester. Among them, ultrasonic dispersion, reaction, and then removal of small molecules in the reaction system to obtain an environmentally friendly titanium-based composite catalyst for polyester; the mass ratio of mesoporous nanospheres to titanium compounds is 0.1~20:1; ethylene glycol and titanium The molar ratio of the compound is 1~100:1; the molar ratio of the metal catalyst promoter to the titanium compound is 0.1~10:1. The invention regulates the catalytic activity of the titanium-based composite catalyst by regulating the size and pore size of the mesoporous nano-microspheres, and the ratio among the mesoporous microspheres, the titanium compound and the metal catalyst assistant. The application of the catalyst in polyester synthesis can effectively reduce the occurrence of side reactions, and simultaneously solve the technical problem of yellowish color of titanium-based catalyzed polyester products. |
