标 题:Synthesis of glycols via transfer hydrogenation of alpha-functional esters with alcohols
发明人：CHAKRABORTY SUMIT; HEMBRE ROBERT THOMAS
权利人:EASTMAN CHEM CO
摘要:A transfer hydrogenation process for forming vicinal diols by hydrogenating 1,2-dioxygenated organic compounds using alcohols as the reducing agent instead of the traditional H 2 gas. The transfer hydrogenation is carried out under milder conditions of temperature and pressure than is typical for ester hydrogenation with H 2 . The milder conditions of operation provide benefits, such as lower operating and capital costs for industrial scale production as well as savings in product purification due to the avoidance of by-products from exposure of reaction mixtures and products to high temperatures.
