Title: Comparing Simple and Fractional Distillation of a Binary Mixture Introduction Distillation is the process used in making alcoholic spirits and separating crude oil into gasoline and other products. Liquid mixtures are most commonly purified by distillation. Distillation is used to separate the components of a mixture by virtue of the difference in their boiling points. There are two processes in distillation, vaporization followed by condensation. First, a liquid mixture is heated until it boils, then the vapor above the boiling liquid is removed, condensed, and collected as a liquid distillate. Figure1. Vapor pressure versus temperature curve Figure2. Boiling Point Diagram for a Two Component Mixture Figure3. Boiling Point Diagram showing the principle of fractional distillation

Table of Reagents Substance Water Methanol Boiling Point (°C) 100°C 65°C Safety Rules Methanol is poisonous and should not be ingested. Avoid breathing the vapors and excessive contact with your skin. Dispose of all solutions in the waste bottle in the hood. Discard used boiling chips in the trash, not in the waste-bottle or in the sinks where they clog the drains. Procedure
