METHOD FOR PRODUCING 1,6-HEXANEDIOL |
摘要 |
<p>A process for producing 1,6-hexanediol by hydrogenation of adipic esters and/or 6-hydroxycaproic esters in the gas phase at elevated temperature and elevated pressure in the presence of chromium-free catalysts comprises hydrogenatinga) over a catalyst comprising copper, manganese and aluminum as essential constituents or over Raney copper,b) at a temperature of from 150 to 230° C. and a pressure of from 10 to 70 bar,c) at a molar ratio of hydrogen to ester to be hydrogenated within the range from 150:1 to 300:1, andd) at a catalyst space velocity of from 0.01 to 0.3 kg of C6 ester per liter of catalyst per hour.</p> |
