Method for manufacturing 2,3-butanediol

The invention relates to a process for manufacturing 2,3-butanediol by hydrogenation of acetoin using a heterogeneous hydrogenation catalyst and under conditions leading to a selectivity higher than 90%. In a preferred embodiment, the hydrogenation is carried out in the presence of no solvent or in...

Zusammenfassung:	The invention relates to a process for manufacturing 2,3-butanediol by hydrogenation of acetoin using a heterogeneous hydrogenation catalyst and under conditions leading to a selectivity higher than 90%. In a preferred embodiment, the hydrogenation is carried out in the presence of no solvent or in the presence of a solvent like water or 2,3-butanediol.
