| titleOfInvention | PROCEDURE FOR OBTAINING DIMETHYLTEREFTALATE FROM LIQUID HEAVY RESIDUES |
| abstract | The invention relates to a process for the preparation of dimethyl terephthalate from boiling residues, residues resulting from the oxidation process of ptooluen together with p-toluic acid methyl ether in the presence of an oxidation catalyst at a temperature of 140-180 grade C and a pressure of 3 to 11 in the fluid phase followed by esterification of the acids obtained with methanol and separation by distillation of the formed esters and then extraction of the oxidation catalysts from the residue by thermal treatment at temperatures of 220 ... 300 ° C C, the thermal treatment being carried out in the presence of 0.02-4 wt.% Of the dissociation catalyst selected from iron acetylacetonate, magnesium acetylacetonate, zinc acetate, after which the dimethyl terephthalate is distilled and the intermediate products recirculated. |
