preparation Embodiment PE1
[0194] Bis(2-hydroxyethyl)terephthalate (508.48 g), dimethyl glutarate (82.14 g), dimethyl 5-sulfoisophthalate sodium salt ( 15.19g), tris(2-hydroxyethyl) trimellitate (2.23g), polyethylene glycol (average molecular weight=1450, 42.38g), sodium acetate (0.76g), manganese (II) acetate Water (0.2363g) and antimony(III) trioxide (0.1902g). The reaction mixture was stirred and heated to 180°C under a slow nitrogen purge. After reaching 180 °C, the reaction mixture was heated to 200 °C within 0.2 h under a slow nitrogen purge and stirring. The obtained reaction mixture was stirred at 200 °C for 1 h under a slight nitrogen purge. Subsequently, the reaction mixture was heated to 275 °C within 1.3 h with stirring under a slight nitrogen purge. The obtained reaction mixture was stirred at 275° C. for 1.2 h under slight nitrogen blowing. During this heating cycle, 67.0 g of colorless distillate was collected. Subsequently, the reaction product entered a full vacuum stage and was st...
preparation Embodiment PE2
[0199] Into a 250 mL glass flask was added bis(2-hydroxyethyl) terephthalate (99.15 g), dimethyl glutarate (16.02 g), dimethyl 5-sulfoisophthalate sodium salt (2.96 g), polyethylene glycol (average molecular weight = 1000) (8.14 g), manganese (II) acetate tetrahydrate (0.042 g) and antimony (III) trioxide (0.034 g). The reaction mixture was stirred and heated to 180°C under a slow nitrogen purge. After reaching 180 °C, the reaction mixture was heated to 200 °C within 0.4 h under a slow nitrogen purge and stirring. The obtained reaction mixture was stirred at 200 °C for 1.1 h under a slight nitrogen blow. Subsequently, the reaction mixture was heated to 275 °C within 1.6 h with stirring under a slight nitrogen purge. The obtained reaction mixture was stirred at 275° C. for 1.2 h under slight nitrogen blowing. During this heating cycle, 9.67 g of colorless distillate was collected. Subsequently, the reaction product entered a full vacuum stage and was stirred at 275°C. The ...
preparation Embodiment PE3
[0203] Into a 250 mL glass flask was added bis(2-hydroxyethyl) terephthalate (99.15 g), dimethyl glutarate (16.02 g), dimethyl 5-sulfoisophthalate sodium salt (2.96 g), polyethylene glycol (average molecular weight = 2000) (8.14 g), manganese (II) acetate tetrahydrate (0.042 g) and antimony (III) trioxide (0.034 g). The reaction mixture was stirred and heated to 180°C under a slow nitrogen purge. After reaching 180 °C, the reaction mixture was heated to 200 °C within 0.3 h under a slow nitrogen purge and stirring. The obtained reaction mixture was stirred at 200 °C for 1.1 h under a slight nitrogen blow. Subsequently, the reaction mixture was heated to 275 °C within 1.3 h under a slow nitrogen purge. The obtained reaction mixture was stirred at 275 °C for 1.0 h under a slight nitrogen blow. During this heating cycle, 7.60 g of colorless distillate was collected. Subsequently, the reaction product entered a full vacuum stage and was stirred at 275°C. The resulting reaction...
