摘要： To reduce acetal concentrations when separating ethanol from a crude product in one or more distillation column, at least one of the columns is operated at a higher pressure to increase the equilibrium constant that favors hydrolysis of the acetal. The crude product may comprise ethanol, acetaldehyde, water and one or more acetals, such as diethyl acetal. The acetal concentration may be reduced thus reducing the need to separate acetal from the crude product.

摘要： A crude ethanol product obtained from the hydrogenation of acetic acid comprises ethanol and ethyl acetate. Using a distillation column operated at a pressure of from 0.1 to 100 kPa, the ethyl acetate and ethanol may be effectively separated. In addition, maintaining the amount of water that is fed to the distillation column to an amount less than 10 wt. %, based on the weight of all components fed to the distillation column, provides an energy benefit.

摘要： A process for purifying an ethanol stream that comprises byproduct, such as aldehyde, acetals, and/or esters, but withdrawing a sidestream comprising ethanol from a distillation column. The sidestream may have a reduced concentration of aldehyde that reduces the formation of acetals in subsequent purification of the ethanol stream.

摘要： Processes for producing alcohols such as ethanol and propanol from a mixed acid feedstock in an integrated process. In one embodiment, the process comprises the step of carbonylating methanol in the presence of a carbonylation catalyst to form a mixed acid feedstock comprising acetic acid and one or more higher acids, preferably comprising propionic acid. The mixed acid feed is hydrogenated in the presence of a hydrogenation catalyst to form a crude alcohol product comprising ethanol and one or more higher alcohols, preferably including propanol.
