Patent

CA 2464762

The invention relates to a method for the production of formic acid formates, by reacting formic acid methyl esters with water and a basic compound, having a pKa value of the corresponding acid of the corresponding dissociation degree which is >= 3, measured at 25 ~C in aqueous solution, by separating the obtained methanol and by optionally adjusting the desired degree of acidity by adding formic acid.

L'invention concerne un procédé de production de formiates de l'acide formique, consistant à faire réagir des esters méthyliques de l'acide formique avec de l'eau et un composé basique, dont la valeur pK¿a? de l'acide correspondant du degré de dissociation correspondant, mesurée à 25 ·C en solution aqueuse, est >= à 3, puis à séparer le méthanol formé et, éventuellement, à ajuster le degré d'acidité souhaité en ajoutant de l'acide formique.
