Document Summary

See chm 1321 introductory organic chemistry laboratory manual 2017, pages 25 27. The 50:50 mixture of 2-propanol and 1-butanol was a clear, colorless liquid. The 50:50 mixture of 2-propanol and 1-butanol smelt mildly like nail polish. The isolated 2-propanol in the receiving flask of both the simple and fractional distillations was a clear, colorless liquid. The isolated 2-propanol in the receiving flask of the simple distillation had a mildly sweet smell that was reminiscent of the smell of glue. The isolated 1-butanol was a clear, colorless liquid. The 1-butanol had a sharp yet sweet smell that was reminiscent to the smell of bananas. The experiment utilizes the difference in boiling points of two substances in order to separate them. Simple distillation involves a heat source and a cooling system. The substance with the lower temperature in the mixture is first to evaporate, and first to cool. Once condensed, it is collected in the retrieving flask.
