Mass of cyclohexene. Cyclohexene is a hydrocarbon with the formula C 6 H 10. This cycloalkene is a colorless liquid with a sharp smell. It is an intermediate in various industrial processes.
Cyclohexene is not very stable upon long term storage with exposure to light and air because it forms peroxides. In Japan cyclohexene is synthesized in a closed system by catalytic hydrogenation of benzene isolated by fractionation stored temporarily in storage tanks and used solely as an intermediate for cyclohexanol synthesis in the same factory. Workers take quality control samples of fractionated cyclohexene once a day and stored cyclohexene once a month.

In this lab cyclohexene is prepared by dehydrating cyclohexanol. At first part of the ex-periment 60 mL of cyclohexanol is treated with sulfuric acid and phosphoric acid and a distillation. The distillate is collected at boiling temperature range of 77 C to 80C.
Product is transferred to a tare sample vial. Fr om a 60 mL of cyclohexanol 229. As the Fig.
3 shows in a triangular diagram cyclohexene is more miscible in the cyclohexane phase than BTA due to the chemical similarities of these components. LLE data coefficient of distribution selectivity for the cyclohexane cyclohexene BTA system at 29815 K and atmospheric pressure in mass fraction are presented in Table 3. This positive charge tends to stay with the ring fragment.

HYDROCARBONS BP 36-216. Low-molecular mass hydrocarbons are colourless gases. Gases can be bubbled through the bromine water if a chemical reaction occurs the colour of the bromine water will fade we say the bromine water decolourises.
The decolourisation of the bromine water indicates that the hydrocarbon is unsaturated. If the bromine water does not decolourise this indicates the presence of a saturated. 34-dimethoxybenzaldehyde cyclohexene hexane MeMe In Part C of the lab take home once you have correctly identified the functional group present in your unknown compounds your TA will provide you with the 1H NMR and 13C NMR spectra for your compounds as well as the compounds molecular formula.
From this data and the results of your experiments above you will then assign the structure. First an acid-base reaction. Hydroxide functions as a base and removes the acidic α-hydrogen giving the reactive enolate.
