Abstract

The distillation process was successfully done because of the separation of water from the acetone. When the distillate was lighted with the matchstick it produced flame which indicates that there was more presence of acetone than water. When the sodium nitroprusside, sodium hydroxide and glacial acetic acid was added to the distillate, it turned to violet. This means that there is the presence of ketone.

Introduction

Distillation is the process heating a liquid until it boils, then condensing and collecting the resultant hot vapors. Distillation is used to purify a compound by separating it from a non-volatile or less-volatile material and it is a commonly used method for purifying and separating mixtures of liquids into their individual components. As the mixture is heated, the temperature rises until it reaches the temperature of the lowest boiling substance in the mixture, while the other components of the mixture remain in their original phase in the mixture. The resultant hot vapor passes into a condenser and is converted to the liquid, which is then collected in a receiver flask. The other components of the mixture remain in their original phase until the most volatile substance has all boiled off. Only then does the temperature of the gas phase rises again until it reaches the boiling point of a second component in the mixture.

The objective is to separate and purify organic compounds.

Experimental Procedure

A 50 mL of a mixture containing 25 mL of acetone and 25 mL of water was placed in a distilling flask. Three pieces of porcelain chips was added to prevent bumping that was produced by a constant stream of bubbles which keeps the liquid in...
