Experiment: Purification of Organic Compounds by Simple Distillation - using a mixture of aqueous ethanol.

Q:Would the total volume of the fractions add up to 80ml (the initial volume) ? Explain why based on your results.

Expert Solution

Distillation is a purification technique where to different liquids are separated if they have different boiling points. The liquid which has low boiling point it gets distilled out first and liquid which has high boiling point gets distilled later. Ideally all fractions you collect should add up to the total initial volume. But practically it may not be possible, because the low boiling point liquid may evaporate to the atmosphere while transferring or handling. Hence practically add up volume may not be same as it was of initial volume of the mixture. But with precaution if we try to reduce the losses then total volume should add up to as it was initially.

Rayleigh distillation An aqueous solution of acetic acid is to be enriched by simple (differential) distillation. The flask is initially charged with 0.025 kmol of solution of composition 0.600 mol fraction water. a) Distillation is continued until the composition of the liquid in the flask has fallen to 0.300 mol fraction water. Assuming that the vapour is completely condensed and collected in a cooled receiver, calculate the quantity and composition of the distillate. b) Repeat the calculation for the case...

After fermentation, a mixture of ethanol and water is sent to a small distillation column. At the top of the distillation column, a 95% ethanol solution at 65°C is produced at a flow rate of 3.5 kg/s. Your job is to design a double-pipe heat exchanger that will cool the 95% ethanol mixture to 40°C by using cooling water that is available at 10°C. Assume an outlet temperature of the cooling water of 55°C, and only use Schedule 40 pipe...

Absolute or 100% ethanol is produced from a mixture of 95% ethanol and 5% water using the Keyes distillation process. A third component, benzene, is added to lower the volatility of the alcohol. Under these conditions, the overhead product is a constat-boiling mixture of 18.5% ethanol, 7.4% water and 74.1% benzene. Use the following data to calculate the volume of benzene that should be fed to the still in order to produce 250 litres of absolute ethanol: density of 100%...
