METHOD FOR RING HYDROGENATION OF DIALKYL TEREPHTHALATES WITH LOW BY-PRODUCT FORMATION

METHOD FOR RING HYDROGENATION OF DIALKYL TEREPHTHALATES WITH LOW BY-PRODUCT FORMATION

A process for ring hydrogenation of dialkyl terephthalates having C3- to C16-alkyl groups can be performed in a hydrogenation unit composed of two reaction units in series. In the process, a suitable process parameter in relation to the first reaction unit is adjusted so that a certain reaction conv...

Zusammenfassung:A process for ring hydrogenation of dialkyl terephthalates having C3- to C16-alkyl groups can be performed in a hydrogenation unit composed of two reaction units in series. In the process, a suitable process parameter in relation to the first reaction unit is adjusted so that a certain reaction conversion is achieved.
