Preparation of dimethyl terephthalate via the air oxidation of p-tolualdehyde |
| abstract |
The invention is directed to a process for the production of terephthalic acid and esters thereof from p-tolualdehyde or mixtures of p-tolualdehyde and p-xylene. The process of the invention can be carried out at lower temperatures and faster throughput than conventional processes using p-xylene. The use of p-tolualdehyde facilitates safety considerations by eliminating the induction period and high oxiding fluid concentrations encountered in typical oxidation reactions which use only p-xylene as the terephthalic acid or ester precursor. |
