A method for the preparation of ethylene glycol by hydrogenation of glycolaldehyde

摘要

described is a method for the production of chlorinated propylene glycol by catalytic hydrogenation of glykolaldehyd in liquid phase using a homogeneous katalysatorsystems from a rutheniumcarboxylatkomplex. this process leads to excellent yields, and selection criteria of ethyleneglycol and allows to work under mild conditions of temperature and pressure.it is compared with corresponding methods using the known rutheniumkatalysatoren much less education. acetalen.
