Title (EN) METAL SALTS OF A DIALKYL ESTER OF 5-SULFOISOPHTHALIC ACID AND METHOD OF PREPARING SAME
(FR) SELS MÉTALLIQUES D'UN ESTER DE DIALKYLE D'ACIDE SULFO-5-ISOPHTALIQUE ET LEUR PROCÉDÉ DE PRODUCTION
Abstract: front page image
(EN) The claimed invention meets these and other objects by providing a method of preparing a metal salt of a dialkyl ester of 5-sulfoisophthalic acid. Broadly speaking, the method provides for the contacting of a dialkyl ester of 5-sulfoisophthalic acid with a metal cation in a buffered reaction mixture to form the metal salt of the dialkyl ester. The reaction mixture is buffered, at least in part, by the acetate of the metal cation. The method according to invention also encompasses various methods of preparing the dialkyl ester of 5-sulfoisophthalic acid.
(FR) La présente invention concerne un procédé pour la préparation d'un sel métallique d'ester de dialkyle d'acide sulfo-5-isophtalique. De manière générale, le procédé prévoit la mise en contact d'un ester de dialkyle d'acide sulfo-5-isophtalique avec un cation métallique dans un mélange réactionnel tamponné pour former le sel métallique de l'ester de dialkyle. Le mélange réactionnel est tamponné, au moins en partie, par l'acétate du cation métallique. Le procédé selon l'invention englobe également divers procédés de préparation de l'ester de dialkyle d'acide sulfo-5-isophtalique.
