PREPARATION OF MIXTURE OF TEREPHTHALIC ACID AND ETHYLENE GLYOL |
| 摘要 |
This method proposes to enhance the flucidity of the mixture and to reduce the content of DEG. The mixture is prepared of terephthalic acid 1 mol, ethylene glycol below 2.0 mol and added with 0.5N alkali hydroxide(MOH) solution. MOH is such as KOH or NaOH, and is used for 0.1-1.0wt. part relative to terephthlic acid 100wt. parts.
