Abstract: 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.

Abstract: 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.
