PROCEDURE FOR THE PRODUCTION OF TEREFTALIC ACID. |
| abstract |
THE TEREFTALIC ACID IS PRODUCED BY OXIDATION OF FOR XYLENE, PURIFIED IN A WATERPROOF PHASE AND RECOVERED BY PRECIPITATION OF A PURIFIED PRODUCT OF THE WATERPROOF PHASE, THE MOTHER LIQUID OF THE WATERPROOF PHASE IS COOLED OR EVAPORATED TO PRODUCE A PRECISE ONE SECOND LIQUOR MOTHER AND THE PRECIPITATE LESS PURE RETURNS TO THE MEANS OF REACTION AND / OR THE WATER OF THE SECOND MOTHER LIQUOR IS USED TO DISSOLVE THE CRUDE SOLID AND / OR THE SECOND MOTHER LIQUOR IS TREATED TO RECOVER WATER THAT IS USED TO WASH THE RECOVERED PRECIPITATE OF THE AQUEOUS SOLUTION. THE PROCESS PRODUCES BETTER PRODUCTIONS OF TEREFTALIC ACID, REDUCES THE USE OF WATER AND REDUCES PROBLEMS IN THE ELIMINATION OF CONTAMINATED WASTEWATER. |
