Process for preparing esters of terephthalic acid |
| abstract |
THE INVENTION RELATES TO THE PREPARATION OF POLYESTERS FROM TEREPHTHALIC ACID AND GLYCOL USING A FLUID MIXTURE OF GLYCOL AND TEREPHTHALIC ACID AS STARTING MATERIAL. THE FLUID MIXTURES CONTAIN GLYCOL TO TEREPHTHALIC ACID IN MOLAR RATIOS OF FROM ABOUT 0.9:1 TO 1,3:1, THE TEREPHTHALIC ACID BEING A MIXTURE OF PARTICLES OF DIFFERENT SIZES. |
