ABSTRACT:
The present invention discloses a chemical method for producing meso-erythritol. The method comprises catalytic hydrogenation of tartaric acid. The tetritol mixture resulting from the hydrogenation can be separated into its components. Alternatively selected components can be isomerized prior to such a separation.
