When compared this numbers to the expected value (70% 2-methylpentane, 30% cyclohexane), the experimental data was lower than that. irritant, With the lower boiling point, 2-methylpentane appeared first in the chromatogram with retention time of 0.724 mins in simple distillation, and 0.712 mins in fractional distillation. chromatography, 2-methylpentane had the lower melting point and evaporated first. 0000003653 00000 n

CHE504 - Lab Report on Distillation Column (L6) (2018) Distillation is a separation process where liquid or vapor mixture of two or more substance is separated into its desired component fractions through boiling and condensation. 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.
