This is an ideal value because it means the experiment was a success and, the amount of solvent recovered was close to the theoretical value. The purpose of this experiment is separate a mixture of a 5% wt methanol-water solution in a binary distillation column. 20mL of Vokda (Antonov) was placed in a pear-shaped distilling flask for heating until the solution boils, the maximum boiling point of it was 100C. On one hand, simple distillation is used to purify l, by separating one liquid component either from nonvolatile substances or from another liquid, simple distillation in that a fractionating column is placed between the distilling flask and t. produces a much better separation between liquids with boiling points closer than 75C. ethanol, Simple Distillation PROCEDURE REPORT AND DATA COLLECTION - The collection and graphing of data will be done on a spreadsheet. The experimenter is ideally an objective observer, and writes his or her reports as such. 746.

The reason was when the mixture was injected into the gas chromatography, 2-methylpentane had the lower melting point and evaporated first. Simple distillation is used to separate liquids whose boiling points are at least 100 degrees apart. Simple Distillation of Cyclohexane Fractional Distillation of Cyclohexane The condenser was After the fractional distillation apparatus was cool, it was disassembled and a simple distillation apparatus was assembled as shown in Figure 2. 2. endobj % to be condensed.
