The procedure for fractional distillation is very similar to that of simple distillation once you have set up your fractional distillation apparatus, place the liquid to be distilled in the distilling flask.
Simple distillation procedure report and data collection - the collection and graphing of data will be done on a spreadsheet download the excel file to collect your data no formal lab report is required for this experiment exercise 11 distillation of a pure compound by simple distillation assemble the simple distillation apparatus.
Distillation: distillation, process involving the conversion of a liquid into vapour that is subsequently condensed back to liquid form it is exemplified at its simplest when steam from a kettle becomes deposited as drops of distilled water on a cold surface distillation is used to separate liquids from. Distillation is the process of separating the components or substances from a liquid mixture by selective boiling and condensation distillation may result in essentially complete separation (nearly pure components), or it may be a partial separation that increases the concentration of selected components of the mixture. Will conduct either the simple distillation procedure or the fractional distillation procedure results will be shared between two groups, so that everyone has data for both simple and fractional distillation also remember methanol and methylene dichloride are flammable never add boiling chips to hot liquid and never.
Fractional distillation - the principle of fractional distillation is based on the establishment of a large number of theoretical vaporization-condensation cycles (theoretical plates): the apparatus of a simple distillation is modified by inserting a fractionating column between the distillation flask and the distillation head, figure 4. Will conduct either the simple distillation procedure or the fractional distillation procedure results will be shared between two groups, so that everyone has data for both simple and fractional distillation also remember methanol and methylene dichloride are flammable never add boiling chips to hot liquid and never distill the flask to dryness.
Fractional distillation is a technique used when separating a mixture of two liquids that do not behave well enough to use simple distillation in this case simple distillation would not be enough to fully separate the two liquids. Assemble the simple distillation apparatus run cooling water through the condenser in at the bottom and out at the top support the round bottom with a securely applied clamp, use a small heating mantle for heat and collect the distillate in a 25 ml graduated cylinder. Simple distillation is a procedure by which two liquids with different boiling points can be separated simple distillation (the procedure outlined below) can be used effectively to separate liquids that have some major degrees difference in their boiling points.
Procedure for simple distillation: 1) take an oven dried 100 ml flask and place 30 ml of cyclohexane ad 30 ml of toluene along with ceramic boiling chip or stones 2) set up the assembly as described above.
