| titleOfInvention | PROCEDURE FOR THE PREPARATION OF ETHYL ACETATE. |
| abstract | Process for the production of ethyl acetate comprising: (a) transforming a C2 starting material comprising ethanol into ethyl acetate in an ethyl acetate production zone by a process selected from: (i) dehydrogenation, and ( ii) reaction with acetaldehyde; (b) recovering a mixture of intermediate reaction products comprising hydrogen and liquefiable products comprising ethyl acetate, ethanol and by-products containing reactive carbonyl groups from the ethyl acetate production zone; (c) contacting at least a portion of the liquefiable products of the intermediate reaction product mixture with a selective hydrogenation catalyst in the presence of hydrogen in a selective hydrogenation zone maintained under selective hydrogenation conditions effective for the selective hydrogenation of by-products containing reactive carbonyl groups to thereby hydrogenate said by-products selectively to hydrogenated by-products comprising the corresponding alcohols; (d) recovering from the selective hydrogenation zone a mixture of selectively hydrogenated reaction products comprising ethyl acetate, ethanol, hydrogen and hydrogenated by-products; (e) distilling the material from the mixture of selectively hydrogenated reaction products in one or more distillation zones so that a first composition comprising substantially pure ethyl acetate and a second composition comprising ethanol and water are produced; (f) treating the second composition of step (e) to separate the water therefrom and giving a third composition comprising ethanol with a reduced water content; and (g) recovering the third composition of step (f). |
