Embodiment 1
[0054] Add 124.2 grams of dimethyl terephthalate, 324 grams of 1,4-butanediol and n-ethyl titanate to a 1000-ml three-necked flask equipped with a thermometer, a mechanical stirrer, a Vigger fractionation column and a condenser. Esters 0.23 g. Heating to raise the temperature, when the temperature in the bottle reaches 100°C, the material begins to melt, then start stirring. When the temperature rises to about 145°C, methanol droplets begin to distill out, and the temperature continues to rise until the temperature in the bottle reaches about 200°C. When methanol is distilled out close to 41 grams, when the theoretical amount is reached, the transesterification reaction is completed, and the heating is stopped and cooled.
[0055] When the internal temperature of the above-mentioned three-necked flask drops below 100°C, add 99.6 grams of isophthalic acid, 153.5 grams of sebacic acid, and 0.2 grams of triphenyl phosphite, then stir and heat up, when the internal temperature ri...
Embodiment 2
[0059] Add 174.6 grams of dimethyl terephthalate, 288 grams of 1,4-butylene glycol, and 84.8 grams of diol and 0.23 grams of n-ethyl titanate. Heating to raise the temperature, when the temperature in the bottle reaches 100°C, the material begins to melt, then start stirring. When the temperature rises to about 145°C, methanol droplets begin to distill out, and the temperature continues to rise until the temperature in the bottle reaches about 200°C. Treat to distill out methyl alcohol close to 58 grams, when reaching theoretical amount, transesterification reaction is finished, stops heating, cools down.
[0060] When the internal temperature of the above-mentioned three-necked flask drops below 100°C, add 99.6 grams of isophthalic acid, 73 grams of adipic acid, and 0.2 grams of triphenyl phosphite, then stir and heat up, when the internal temperature rises to about 160°C , with water distilling out, continue to heat up to about 210°C. The amount of water distilled is clos...
Embodiment 3
[0064] Add 174.6 grams of dimethyl terephthalate, 432 grams of 1,4-butanediol, and 74.4 grams of ethylene glycol in a 1000-milliliter three-necked flask equipped with a thermometer, a mechanical stirrer, a Vigre column and a condenser. gram and 0.31 gram of n-butyl titanate. Heating to raise the temperature, when the temperature in the bottle reaches 100°C, the material begins to melt, then start stirring. When the temperature rises to about 148°C, methanol droplets begin to distill out, and the temperature continues to rise until the temperature in the bottle reaches about 200°C. Treat to distill out methyl alcohol close to 58 grams, when reaching theoretical amount, transesterification reaction is finished, stops heating, cools down.
[0065] When the internal temperature of the above-mentioned three-necked flask drops below 100°C, add 149.4 grams of isophthalic acid, 175.2 grams of adipic acid, and 0.25 grams of triphenyl phosphite, then stir and raise the temperature. Whe...
