| titleOfInvention | Preparation method of polyester resin with low acetaldehyde content |
| abstract | The invention relates to a preparation method of polyester resin with low acetaldehyde content, which mainly solves the problem that the residual amount of acetaldehyde after injection molding of polyester products, especially bottle sheets, prepared by the prior titanium catalyst is high, and adopts a catalyst comprising the reaction product of the following raw material substances: 1) titanium compound a having the general formula: ti (OR) 4 (ii) a 2) Selected from diols B having 2 to 10 carbon atoms; 3) a metal compound C selected from group IA of the periodic Table of the elements; 4) at least one aliphatic organic acid D selected from organic acids; 5) at least one phosphate compound E selected from phosphorus compounds; 6) at least one metal compound F selected from IIA, IB, IIB, VIIB and VIII in the periodic table of elements; 7) the technical scheme of the nitrogen-containing compound G selected from organic amine or organic ammonium better solves the problem and can be used in the industrial production of the polyester resin with low acetaldehyde content. |
