Abstract
Vapor-liquid equilibria of 1-butanol+ethanol and isoamyl alcohol+ethanol systems containing a minute amount of crotonaldehyde were measured at atmospheric pressure using an Othmer-type still. Equilibrium ratio curves of the trace component (crotonaldehyde) are shown to exhibit a characteristic shape.<BR>Batch rectification experiments of ethanol, 1-butanol, 1-butanol+ethanol and isoamyl alcohol+ethanol systems containing 0.1 wt% crotonaldehyde were carried out using a glass Oldershow-type column.<BR>The lowering of the concentration of the trace component in distillate becomes gentle with the progress of distillation. The distillation curves of the trace component are found to show a peak at the change of distillate of the major components. In the residue of batch rectification of 1-butanol and isoamyl alcohol solutions, crotonaldehyde was detected in much higher concentration than in the last distillate.
