MOBILITY IMPROVING METHOD OF THE MIXTURE OF TEREPHTHALIC ACID AND GLYCOLS |
| 摘要 |
The fluidity of a terephthalic acid(I)-glycol slurry was improved by adding 0.01-15%(based on glycol)I mono(hydroxyalky1)ester and its alkali metal salt. A slurry of 332 parts I in 186 parts ethylene glycol, prepd. by partial hydrolysis of diester, to reduce the stirring torque (90 rpm at 90≦̸C) from 0.3 to 0.1 kg-cm. 1,4-Butanediol was also used as the glycol.
