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