Patent

CA 2495369

The invention relates to a method for producing formates according to which: (a) methyl formate is partially hydrolyzed with water; (b) methyl formate and methanol are separated by distillation from the reaction mixture obtained in step (a) while forming a stream containing formic acid and water, and; (c) the stream containing formic acid and water from step (b) is brought together with the corresponding formate while forming a mixture containing the formate and water. The invention also relates to a device for producing these formates and to the use thereof.

L'invention concerne un procédé permettant de produire des formiates, selon lequel : (a) de l'ester de méthyle d'acide formique est hydrolysé partiellement avec de l'eau ; (b) de l'ester de méthyle d'acide formique et du méthanol sont séparés, par distillation, du mélange réactionnel résultant de l'étape (a) du procédé, de manière à former un flux contenant de l'acide formique et de l'eau ; et (c) le flux contenant l'acide formique et l'eau, résultant de l'étape (b) du procédé, est associé au formiate correspondant, de manière à former un mélange contenant le formiate et l'eau. L'invention concerne également un dispositif permettant de produire lesdits formiates et leur utilisation.
