Abstract (en)

[origin: WO8000837A1] Monoesters of symmetrical dicarboxylic acids and symmetrical diols are prepared in high yield by reacting a di-acid or a diol with a monohydric alcohol or monocarboxylic acid, respectively, in an aqueous solution. The resultant monoester is removed from the aqueous solution immediately after its formation by continuous extraction with a nonpolar solvent.

Abstract (fr)

Des monoesters d'acides dicarboxyliques symetriques et de diols symetriques sont prepares avec de hauts rendements par la reaction d'un diacide ou d'un diol avec un alcool monohydrique ou un acide monocarboxylique, respectivement, en solution aqueuse. Le monoester resultant est extrait de la solution aqueuse immediatement apres sa formation par extraction continue avec un solvant non-polaire.
