Methods for reducing the fouling of process equipment used in the manufacture of aromatic compounds such as dimethyl-2,6-naphthalenedicarboxylate are disclosed. The methods require treating manufacturing process streams with a metal complexing agent. Novel compositions useful in the manufacture of aromatic materials such as dimethyl-2,6-naphthalenedicarboxylate also are disclosed.
La présente invention concerne des procédés de réduction d'encrassement d'un équipement utilisé dans la fabrication de composés aromatiques tels qu'un diméthyl-2,6-naphtalènedicarboxylate. Lesdits procédés requièrent le traitement des courants utilisés lors de la fabrication par un agent métallique complexant. La présente invention concerne également de nouvelles compositions utilisées dans la fabrication de matières aromatiques telles qu'un diméthyl-2,6-naphtalènedicarboxylate.
