Development on Recovery of MFB from Industrial Waste without Second Pollution

摘要

DMT (dimethyl terephthalate, (1)) is well-defined raw material for PET production. In commercial DMT 1 has been synthesized from p-xylene in air oxidation followed by esterification (Figure 1). In this process, partial oxidation of xylene gave rise to major by-products MFB (methyl 4-formylbenzoate, (2)) and MMB (methyl 4-methylbenzoate, (3)).
