Embodiment 1
[0044] Step 1: Preparation of Biomass Polyester Chips
[0045] Add 160kg of bio-based 2,5-furandioic acid and 65kg of bio-based ethylene glycol, 8kg of bio-based 1,3-propanediol in the reactor, wherein the component of bio-based ethylene glycol: the quality of ethylene glycol The fraction is 90%, the mass fraction of 1,2-propanediol is 5%, the mass fraction of 1,2-butanediol is 2%, the mass fraction of pentanediol is 2%, and the mass fraction of sorbitol is 1%. The amount of the catalyst was 275 ppm each of titanium dioxide and antimony trioxide, which were 45.65 g, respectively. 46 g of trimethyl phosphate and 69 g of antioxidant 1010 were added. After mixing uniformly, the esterification reaction was carried out at 225° C. under the pressure of 0.343MPa, and the reaction time was 4h. After esterification, the product was transported to the polycondensation kettle, and at the same time, the temperature was raised to 260°C for polycondensation reaction, and the polycondensat...
Embodiment 2
[0051] Step 1: Preparation of Biomass Polyester Chips
[0052] In the reactor, add the bio-based 2 of 166kg, 5-furandioic acid and the bio-based ethylene glycol of 93kg, the bio-based 1,3-propylene glycol of 11kg, wherein the component of bio-based ethylene glycol is: The mass fraction is 99.2%, the mass fraction of 1,2-propanediol is 0.4%, the mass fraction of 1,2-butanediol is 0.2%, the mass fraction of pentanediol is 0.1%, and the mass fraction of sorbitol is 0.1%, The added catalyst was 120 ppm of tetrabutyl titanate, and it was 19.92 g. 52g of trimethyl phosphate was added, and after mixing uniformly, the esterification reaction was carried out at 280° C. and 0.323MP, and the reaction time was 0.5h. After the esterification, the product was transported to the polymerization kettle, and at the same time, the temperature was raised to 290° C. to carry out the polycondensation reaction, and the polycondensation time was 2h. Finally, the all-bio-based polyester is obtained,...
Embodiment 3
[0058] Step 1: Preparation of Biomass Polyester Chips
[0059] Add the bio-based 2 of 166kg in the reactor, and the bio-based ethylene glycol of 5-furandioic acid and 80kg, the bio-based 1,3-propylene glycol of 9kg, wherein the component of bio-based ethylene glycol is: The mass fraction is 95%, the mass fraction of 1,2-propanediol is 2%, the mass fraction of 1,2-butanediol is 1.5%, the mass fraction of pentanediol is 1%, and the mass fraction of sorbitol is 0.5% , the added catalyst is antimony trioxide, 550ppm, 91.3g. 49 g of alkyl phosphoric acid diester and 49 g of antioxidant 168 were added. After mixing evenly, the esterification reaction was carried out at 240° C. under the pressure of 0.443MPa, and the reaction time was 1.5h. After esterification, the product was transported to the polymerization kettle, and at the same time, the temperature was raised to 280° C. to carry out the polycondensation reaction, and the polycondensation time was 5h. Finally, the all-bio-b...
