During this lab, students were given 30 mL of an unknown solution containing two colorless chemicals. acetone, irritant, Simple Distillation Lab Report. A simple distillation is used if the components have widely different boiling points (greater than a 100 C difference in boiling points). The vapor then goes through the condenser where it is liquefied by cold circulating water.

In your notebook, record the chromatography conditions used for the analyses. In simple distillation, the area percent of 2-methylpentane was 64% and 35% Ryan Huckaby The experimenter is ideally an objective observer, and writes his or her reports as such. Simple Distillation is most commonly used for liquids that have, significantly different boiling points, usually twenty-five degrees or more apart. connected to the round bottomed flask and the adapter. 33-qO%)SR{HWS!*8})S#:EA rO)8i`q DB9p I, 2H:ea3H + Simple distillation can be used when the liquids to be separated have boiling points that are quite different. condenser. ethyl ether, 0000006555 00000 n Mohrig, J., Albert, D., Hofmeister, G., et al; Laboratory Techniques in Organic Weldegirma, S. Experimental Organic Chemistry, 9 th ed. Fig. The 2-methylpentane with lower melting point evaporated Distillation is also an excellent purification tool for many liquids, and can be used to purify products from a chemical reaction. However, the experimental values are lower than expected value (95% 2-melthylpentane and 5% cyclohexane) due to the high set temperature of hot plate at the beginning. water. the components.

The percent recovery for both ethanol and 2-propanol were both 0%. The percent area of 2-methylpentane is higher in fractional distillation than simple distillation, thus fractional distillation separates the product much purer than simple distillation.
