| Terephthalic acid production |
|
|
Terephthalic acid is used to produce polyethylene terephthalate (PET) by catalytic oxidation of p-xylene in acetic acid in the presence of air. To ensure an optimal reaction the catalyst is mixed into the xylene/acetic acid mixture.
The static mixer SMI™ provides within short distance a homogeneous mixture between the catalyst, xylene and acetic acid to ensure the optimal operating condition of the catalyst.
