Method of purifying dimethyl-terephthalate |
| abstract |
A PROCESS FOR THE PURIFICATION OF CRUDE DIMETHYL TEREPHTHALATE DERIVED FROM P-XYLENE. THE CRUDE DIMETHYL TEREPHTHALATE IS CONTACTED WITH MOLECULAR OXYGEN IN THE PRESENCE OF A COBALT-COMPRISING MATERIAL, A BROMINE-COMPRISING MATERIAL, AND IF DESIRED, A MANGANESE-COMPRISING MATERIAL. BOTH THE COBALT-COMPRISING MATERIAL AND THE BROMINECOMPRISING MATERIAL ARE SOLUBLE IN THE CRUDE DIMETHYL TEREPHTHALATE. |
