Method for the recovery of dimethyl terephthalate and intermediate products thereof |
| abstract |
A method of recovering dimethyl terephthalate and the intermediate products thereof which comprises heating a starting distillation residue to 260* - 400*C. to form dimethyl terephthalate and the intermediate products thereof and recovering them; said starting distillation residue resulting from the steps of oxidizing p-xylene and/or methyl p-toluate at liquid phase with molecular oxygen or a molecular oxygencontaining gas, in the presence of A. manganese metal or a manganese compound which is at least partially soluble in the reaction system, and B. cobalt metal or a cobalt compound which is at least partially soluble in the reaction system, esterifying the resulting reaction mixture with methanol, and distilling the esterified product to separate therefrom the formed crude dimethyl terephthalate and other products having the boiling points lower than than of dimethyl therephthalate. |
