titleOfInvention | A liquid polyester-titanium composite catalyst and its preparation method and application |
abstract | The invention discloses a liquid polyester-titanium composite catalyst and a preparation method and application thereof. The preparation method of the liquid polyester-titanium composite catalyst of the present invention comprises the following steps: mixing the titanium-based compound and the first solvent and then performing a reflux reaction to obtain a white or pale yellow suspension a; dissolving cobalt acetate in the second solvent, The solution b is obtained; the suspension a, the solution b, the phosphate ester, etc. are mixed and then heated and reacted. When the heating reaction ends, the system is a solution, and the obtained solution is a liquid polyester titanium composite catalyst. The liquid polyester titanium composite catalyst prepared by the invention has good stability, does not contain heavy metals, has high catalytic activity, and can effectively improve the efficiency of polycondensation reaction. The polyester prepared by using the catalyst has good hue, high intrinsic viscosity, narrow molecular weight distribution and high performance. It is excellent, and the preparation method of the catalyst is simple and requires low equipment. |
