Free essay: simple distillation, gas chromatography: preparation of synthetic banana oil introduction this experiment gave us the opportunity to work with a. Fractional distillation is also similar to gas chromatography, since both processes separate the components of a mixture primarily based on boiling point (or vapor pressure) differences however, fractional distillation is typically used to separate components of a mixture on a large scale, whereas gc can be used on a much smaller scale (ie . Fractional distillation essay 2/21/13 fractional distillation with an introduction to gas chromatography when heating a mixture of two or more liquids, even with quite different boiling points, some of the heavier liquid will vaporize and contaminate the recovered lighter liquid. Distillation and gas chromatography lab calculations: • if any of the gc spectra contain more than two peaks, calculate the percent composition for each ester in said fraction, as described in the lab handout.
Gas chromatography offers a valuable analytical tool in following the course of the fractional distillation of multi-component systems in those cases where dif- ferences in boiling points are small and differences in refractive indices are non- existent, gas ct~romatography is virtually indispensable.
