Abstract

PURPOSE: To prapare various kinds of polyesters suitable for various applications, by introducing a slurry consisting of specific molar ratio of a TPA and EG to a distance esterification reaction zone, and then charging to respective batchwise esterification reactor.
CONSTITUTION: A slurry of EG and TPA wherein the molar ratio of EG/TPA is 0.80W1.70, is stored in a slurry tank 8, and introduced to a slurry supply tank 41 in an esterification reaction zone with a pump 9. The slurry is then introduced to a primary slurry supply line 45 with a primary slurry supply pump 42, and then branched and continuously introduced to esterification reactors 50, 50', etc., with secondary slurry supply pumps 47, 47', etc. to carry out the esterification reaction. The amount of slurry in the slurry tank 8, and the amounts of TPA and EG, are controlled by cascade control. An intermediate slurry tank 33 and a pump 34 are preferably provided before the esterification reaction zone. The pump is pref. a snake pump.
