    摘要: A process for preparing ethylene glycol wherein a mixture of carbon monoxide and hydrogen is contacted at an elevated temperature and pressure and in the presence of a solvent with a ruthenium compound and a promoter, such as pyrocatechol. In another aspect this invention relates to the preparation of ethylene glycol ethers from carbon monoxide and hydrogen.
