The Cyclohexylbenzene with CAS registry number of 827-52-1 is also known as Benzene,cyclohexyl-. The IUPAC name is Cyclohexylbenzene. It belongs to product categories of Biphenyl & Diphenyl Ether. Its EINECS registry number is 212-572-0. In addition, the formula is C12H16 and the molecular weight is 160.26. What's more, it is a colourless liquid and should be sealed in cool, dry place.
Physical properties about Cyclohexylbenzene are: (1)ACD/LogP: 4.74; (2)ACD/LogD (pH 5.5): 4.74; (3)ACD/LogD (pH 7.4): 4.74; (4)ACD/BCF (pH 5.5): 2348.77; (5)ACD/BCF (pH 7.4): 2348.77; (6)ACD/KOC (pH 5.5): 9004.16; (7)ACD/KOC (pH 7.4): 9004.16; (8)#Freely Rotating Bonds: 1; (9)Index of Refraction: 1.522; (10)Molar Refractivity: 52.11 cm3; (11)Molar Volume: 170.6 cm3; (12)Surface Tension: 34.5 dyne/cm; (13)Density: 0.939 g/cm3; (14)Flash Point: 93.2 °C; (15)Enthalpy of Vaporization: 46.01 kJ/mol; (16)Boiling Point: 242.6 °C at 760 mmHg; (17)Vapour Pressure: 0.0524 mmHg at 25 °C.
Preparation of Cyclohexylbenzene: Firstly, cyclohexene is added to benzene and sulfuric acid mixture under stirring at the temperature of 10-20 °C for 0.5-1 hour. Then the mixture is heated for another 1 hour. Secondly, reservoir is washed by water and lye, and then it is fractionated. At last, product is obtained by collecting distillate at 230-260 °C and distillate at the boiling point.
Uses of Cyclohexylbenzene: it is used to produce 1-cyclohexyl-4-nitro-benzene. The reaction occurs with reagents HNO3, HOAc at the temperature of -10 °C for 30 minutes. The yield is about 57%.
When you are using this chemical, please be cautious about it. As a chemical, it is irritating to eyes, skin and it is harmful if swallowed. What's more, it is very toxic to aquatic organisms that may cause long-term adverse effects in the aquatic environment. This material and its container must be disposed of as hazardous waste. During using it, avoid release to the environment. If contact with eyes accidently, rinse immediately with plenty of water and seek medical advice.
