Abstract

Reivindicación 1: Una composición de etanol que comprende: (a) por lo menos 85% en peso de etanol; (b) menos del 12% en peso de agua; y (c) entre 95 ppm en peso y 850 ppm en peso de isopropanol.Reivindicación 93: Una composición de etanol que se prepara mediante un proceso que comprende los pasos de: hidrogenar una corriente de alimentación de ácido acético en presencia de un catalizador para formar un producto de etanol crudo; separar por lo menos una porción del producto de etanol crudo en una primera columna para dar un primer destilado que comprende etanol, agua y acetato de etilo, y un primer residuo que comprende ácido acético; separar por lo menos una porción del primer destilado en una segunda columna para dar un segundo destilado que comprende acetato de etilo y un segundo residuo que comprende etanol y agua; y separar por lo menos una porción del segundo residuo en una tercera columna para dar un tercer destilado que comprende la composición de etanol y un tercer residuo que comprende agua.Claim 1: An ethanol composition comprising: (a) at least 85% by weight of ethanol; (b) less than 12% by weight of water; and (c) between 95 ppm by weight and 850 ppm by weight of isopropanol. Claim 93: An ethanol composition that is prepared by a process comprising the steps of: hydrogenating an acetic acid feed stream in the presence of a catalyst for form a crude ethanol product; separating at least a portion of the crude ethanol product in a first column to give a first distillate comprising ethanol, water and ethyl acetate, and a first residue comprising acetic acid; separating at least a portion of the first distillate in a second column to give a second distillate comprising ethyl acetate and a second residue comprising ethanol and water; and separating at least a portion of the second residue in a third column to give a third distillate comprising the ethanol composition and a third residue comprising water.
