From the graph shows the relationship between the volume of distillation temperatures. It was found that the initial temperature of the delete service pure ethanol distillation came out first drop 76° c. Then the temperature rising up to 78 degrees Celsius. Where is the boiling point of ethanol that is hypocrisy, pure ethanol, but that more. But in an experiment that measured temperature distillation of pure ethanol, but that increased to 80° c. Shows that ethanol may be impurities, and trembles from the graph of the relationship between the temperature of a several volume ethanol delete pure service with 50% ethanol-water 50% ethanol-water. The boiling point temperature higher.
