Introduction:

In this experiment a simple distillation of crude oil is performed. The crude oil is separated into gasoline, kerosene, and lubrication oils. The chemical properties of the components of crude oil influence at which temperature it distills out of the crude oil.

Procedure:

Set up distillation apparatus with a 100 mL Round Bottom Flask. Attach heating mantel, distillation head, condenser, and distillation take off. Place a 100mL graduated cylinder under the distillation take off. Record initial chemical properties of crude oil. Then, begin distillation by maintaining a level of heat so there is continuous drops running into the cylinder. Record the temperature when the first drop falls from the end of the condenser. Record the volumes of distillate condensed at each of the temperatures indicated. Record color and temperature at 5mL and 25mL. Finally, record the order and temperature at which the components fully distill.

Observation and Results:

Temperature at which crude oil begins to boil 176F

Temperature at which first drop falls from the end of the condenser 196F

Initial Chemical Properties of Crude Oil
13g Gasoline

16g Kerosene

20.5g Lubricating Oils
