Michele Chan 2211L 9/23/10 Adna Muliawan Discussion According to the graphs and the results obtained from the two types of distillation, fractional distillation appeared to be more accurate. The boiling point for simple distillation was 75 degree Celcius and the boiling point for fractional distillation was 67 degree Celcius. However, when looking at the graphs, this is a significant change or jump in the temperature in the fractional distillation, whereas the simple distillation remains at a steady gradual increase of temperature without a monumental change. The gradual increase in temperature is an indicator that the vapor is not pure. Therefore, we believe that the boiling point of 67 degree Celcius is more accurate. Based on that assumption, we compared it to the literature boiling points of water, ethanol and methanol and concluded that the mixture was made up of water and methanol as methanol had a literature boiling point of 65 degree Celcius. Furthermore, the concluding temperature of our substance ended up being 96 degree Celcius
