Why do we use a thermometer in fractional distillation?

WebbFew fractional distillation apparatuses are required for the process. It includes distilling flask, condenser, receiver, fractionating column, thermometer and heat source. After setting up the apparatus, a mixture of two miscible liquids A and B is taken where A has more volatility than substance B. WebbThe apparatus for simple distillation is set up as shown in Figure 1. Thermometer is put into the thermometer pocket. When boiling, the liquid is heated at constant rate, which is until the distillation rate is about 2-3 drops per second. A stable temperature as the boiling point of the liquid to be distilled is recorded. ryan reynolds ny house https://gkbookstore.com
