AI Technical Summary
Technical Problem
Existing titanium-based catalysts suffer from hydrolysis and precipitation problems during polyester preparation, and common treatment methods result in high economic costs, significant safety risks, or a decline in polyester performance.
Method used
A titanium-containing composition is prepared by reacting titanium compounds, solvents, hydroxycarboxylic acids and/or amino acids in stages to avoid gel formation.
Benefits of technology
The preparation process proceeded smoothly, avoiding the introduction of low-flash-point compounds, resulting in a homogeneous liquid-phase catalyst that improved the stability and safety of the polyester without affecting its performance.

Abstract
The invention discloses a titanium-containing composition, a preparation method thereof and a polyester catalyst, and relates to the technical field of polyester catalysts, and the titanium-containing composition comprises reaction products of the following components: a titanium compound, a solvent, hydroxycarboxylic acid and / or amino acid. The titanium-containing composition is obtained by mixing and reacting the titanium compound, the solvent, the hydroxycarboxylic acid and / or the amino acid, the solvent adopts ethylene glycol ester, the flash point is high, the reaction activity with titanium is low, the preparation process is very smooth, meanwhile, the performance change of polyester is not caused when the titanium-containing composition is used for polyester, and the technical effect is good.
