Continuous process for selective conversion of hexaldehyde-producing carbohydrates to ethylene glycol using low concentrations of reverse aldol catalysts

Reverse aldol processes are disclosed that use very low concentrations of a reverse aldol catalyst in combination with a hydrogenation catalyst having certain activity, size and spatial dispersion to achieve high selectivity for ethylene glycol. 本发明公开了逆羟醛方法，所述方法使用非常低浓度的逆羟醛催化剂与具有某些活性、尺寸和空间分散的氢化催化剂的组合，以获得对于乙二醇的高选择性。
