Abstract
A process is provided for catalytic hydrogenation of glycolaldehyde to form ethylene glycol in liquid phase employing a homogeneous ruthenium catalyst and a basic promoter. Ethylene glycol is produced in excellent yields and selectivities, and the process permits use of mild temperature and pressure conditions.
