| Abstract: | Purging nitrogen gas into a 20 mL reactor,the effect of nitrogen on the esterification rate was discussed under the traditional polyester esterification conditions.The results showed that as compared with traditional process,the esterification rate was increased by 19.18% for purging the reactor with nitrogen gas and by 27.7% for purging the gas phase in the reactor with nitrogen gas.Purging the esterification reactor with nitrogen gas is helpful to raising the esterification rate of polyester. |
