3C. Below are the gas chromatography results of two separate distillations of the same 1:1 mixture of ethanol and 1-butanol. One sample was obtained from the first fraction of a simple distillation and one sample was obtained from the first fraction of a fractional distillation. Identify the peaks in the chromatographs. Discuss the conclusions you can make regarding simple distillation compared with fractional distillation. Which method was more successful?
