| Summary: | This research had as purpose a pre-treatment proposal for sodium phthalate in the company IQN S.A.S. In order to comply with this objective, a diagnosis was made of the current state of the process in which phthalic acid is produced from impure sodium phthalate (SAP), in which it was determined that the main cause of the low percentage of purity obtained (88 , 76%) is due to the raw material used (SAP). This value was found by HPLC liquid chromatography and a separation method for sodium phthalate was then evaluated by means of water and ethanol solubility tests in order to know the behavior of the SAP in each of these solvents , Identifying that it is totally soluble in water and little soluble in ethanol; In addition to these treatments, coagulation tests were carried out by varying the acidity of the solution, finding that at a pH of 6 it precipitates a greater amount of impurities suspended in the solution. |
