titleOfInvention | Method for producing polyethylene terephthalate |
abstract | A method for producing polyethylene terephthalate with high catalytic activity is provided. A method for producing PET comprises subjecting a low-order condensate of terephthalic acid and ethylene glycol to liquid-phase polycondensation in the presence of a catalyst to form a liquid-phase polycondensation PET, and then subjecting the PET to solid-phase polycondensation. In the production, the following titanium-based catalyst is used as the catalyst, and the liquid-phase polycondensation PET having a COOH group concentration of 50 equivalents / ton or less is subjected to solid-phase polycondensation. Titanium-based catalyst: hydrolyzate of titanium halide, solid titanium composite obtained by dehydrating and drying the hydrolyzate in the presence of polyhydric alcohol, or a solution in which these are dissolved in a liquid containing ethylene glycol, titanium halide And a solid titanium composite obtained by dehydrating and drying the mixture of a mixture of at least one element selected from elements other than titanium with a compound of at least one element selected from the group consisting of: Is dissolved in a solution containing ethylene glycol.
