Simple Distillation Of Hexane-Octane

Hexane-Octane Results

The mixture that was used in this simple distillation experiment was hexane and octane. During the time the first fraction of hexane-octane mixture was collected, the temperature range was discovered to be at 41.9°C -42.5 °C. The peak area of the first fraction appeared to be 95.70 at 0.710 minutes, and 4.30% at 1.38 minutes. During the second fraction, the temperature ranges was discovered to be at 43.2°C-47.8°C. The peak area of the second fraction appeared to be 100% at 1.15 minutes. The third fraction of hexane-octane was collected, but the sample was not taken for distillation due to the teacher assistant’s specific instructions. During the fourth fraction, which consisted the remainder of the solution, the temperature

The other group’s simple distillation experiment consisted of the alkane mixture of hexane-heptane. The results of the other group’s mixture were similarly conducted in the same experimental manner, therefore the temperature and the area and time were recorded in a respective manner. The first fraction of the hexane-heptane was recorded to have the temperature ranges of 65.9°C-71.2°C. The peak area of the first fraction appeared to be 65.76% at ———, and 34.24% at ———-. During the second fraction, the temperate ranges was recorded to be 76.4°C-80.2°C. The peak area of the second fraction were 58.77% at ——— and 39.86% at ———-. The third fraction of hexane-heptane was collected, but the sample was not taken for distillation due to the teacher assistant’s specific instructions. The fourth fraction of the hexane-heptane mixture temperature ranges were not available. The peak of the fourth fraction appeared to be 24.29% at ——- and 75.71% at ——-. All three fractions of the hexane-octane mixture that were taken during the experiment were evaluated by a gas chromatogram. The other group’s first graph showed two peaks which consisted of hexane and heptane. The hexane was more dominant in the first graph. However, the second and third graphs showed that hexane’s peak area decreased over time while the area of heptane increased over time. This was due to heptane having a higher boiling point than hexane. Therefore, a larger amount of heptane was distilled and passed through the vessel in the gas
