2.27 mL cyclohexanol x 0.962 = 2.18 g 2.18g / 4.81 g x 100 = 45.32 % Discussion: The purpose of this experiment was to produce cyclohexanol from a hydration of cyclohexene. The reaction consists of three phases, including an intermediate of cyclohexyl hydrogen sulfate that is produced when H 2 SO 4 is added to the cyclohexene reactant. H 2 O is then added at high temperatures to produce cyclohexanol. (1) 3.5 mL of concentrated sulfuric acid, 1.7 mL of H 2 O and 5.0 mL of cyclohexene were added, in that order, to a round bottom flask and stirred with a magnetic bar. Magnetic bar was removed, boiling stones were added and a steam distillation was
