摘要: (57) dehydrogenation catalyst, for example [summary] ethanol is dehydrogenated over copper catalyst on silica Te to the presence of hydrogen. It is selectively hydrogenated with a suitable catalyst on such ruthenium 5% on carbon, where liquefiable products present in the intermediate reaction product mixture in the resulting corresponding reactive carbonyl-containing by-products selectively I like to be hydrogenated to alcohols. By boiling point of them approximate the Re husband of ethyl acetate, will cause difficulties Te the purification of ethyl acetate product and butan-2-one n- butyl aldehyde, respectively 2 by it if it is some - it is hydrogenated to n- butanol and butanol. It is used to purify the product, which is hydrogenated in the next distillation process of the two stages. It is operated below the absolute (10 Pa 4 ×) about 4 bar, typically, whereas distillation zone of the first from the absolute (10 Pa 4 ×) about 4 bar is typically distillation zone of the second is operated at pressures of up to (10 Pa 2.5 ×) about 25 bar. Is distilled in a distillation zone of the second, and ethyl acetate to about 99.95 mole% to about 99.8 mol%, typically so that the fraction of the first water ethyl acetate, and ethanol produced by distillation zone a first The manufacture and second
fraction of the overhead and bottoms product consisting of the first distillation and then, have a composition different from those produced Te the distillation zone of the first fraction of the second the
reactive carbonyl specieszone, above the feed point for the liquefiable products of the reaction product mixture are selectively hydrogenated, preferably the back.
