Title
(EN) PREPARATION OF PLASTICIZER ESTERS FROM PHTHALIC ANHYDRIDE RESIDUE
(FR) PREPARATION D'ESTERS A POUVOIR PLASTIFIANT A PARTIR DE RESIDUS D'ANHYDRIDE PHTALIQUE
Abstract
(EN)
A process for the formation of esters from at least one phthalic anhydride residue stream produced from the vapor phase oxidation of o-xylene, naphthalene and/or the like which comprises: (a) adding a phthalic anydride residue stream and a mono-alcohol to a reaction vessel to form a reaction mixture; and (b) heating the reaction mixture and maintaining a pressure sufficient to obtain boiling of the reaction mixture thereby converting any acid and/or anhydride components of the phthalic anydride residue stream to an ester.
(FR)
Cette invention se rapporte à un procédé pour la formation d'esters à partir d'au moins un courant de résidus d'anhydride phtalique produit par l'oxydation en phase vapeur de o-xylène, de naphtalène et/ou d'autres composés similaires. Ce procédé consiste: a) à ajouter un courant de résidus d'anhydride phtalique et un mono-alcool dans un récipient de réaction, afin de former un mélange de réaction; et b) à chauffer ce mélange de réaction et à y maintenir une pression suffisante pour porter à ébullition le mélange de réaction, de façon à convertir en esters tous les constituants acides et/ou anhydrides du courant de résidus d'anhydride phtalique.
