Title (EN) RECYCLING 2,6-NAPHTHALENEDICARBOXLIC ACID (2, 6-NDA) CONTAINED IN POLYETHYLENE NAPHTHALATE IN A PROCESS TO PRODUCE DIESTERS
(FR) RECYCLAGE D'ACIDE DE 2,6 NAPHTALENE DICARBOXYLIQUE (2,6-NDA) CONTENANT UN NAPHTALATE DE POLYETHYLENE VUE DE L'OBTENTION DE DIESTERS
Abstract: front page image
(EN)A process for preparing a dialkylester of a naphthalenedicarboxylic acid comprising directing a liquid phase reaction mixture comprising a low molecular weight alcohol, a naphthalenedicarboxylic acid, a dialkylester of a naphthalenedicarboxylic acid, and a polyethylene naphthalate containing material, at a given temperature and pressure through series arranged reaction zones and subsequently removing a product comprising a dialkylester formed by the reaction of the naphthalenedicarboxylic acid and the polyethylene naphthalate containing material with the low molecular weight alcoholfrom a reaction zone. This invention is also directed to a process for preparing a purified dialkylester of a naphthalenedicarboxylic acid comprising a series of crystallization and distillation steps, and combinations thereof.
(FR)Procédé d'obtention d'un dialkylester d'acide de napthalène dicarboxylique, consistant à faire passer un mélange réactif en phase liquide comprenant un alcool à faible poids moléculaire, un acide de naphtalène dicarboxylique, un dialkylester d'acide de naphtalène dicarboxylique et un matériau contenant un napthalate de polyéthylène naphtalate à une température et sous une pression données au travers de zones de réaction disposées en série, puis ultérieurement à retirer un produit comprenant un dialkylester formé par réaction de l'acide de naphtalène dicarboxylique et du matériau contenant un naphtalate de polyéthylène avec l'alcool à faible poids moléculaire à partir d'une zone de réaction. Cette invention concerne également un processus de fabrication du dialkylester purifié d'acide de naphtalène dicarboxylique englobant une séries d'étapes de cristallisation et de distillation, séparées ou en combinaison.
