Specification

The 2-Phenylethyl bromide with CAS registry number of 103-63-9 is also known as Benzene,(2-bromoethyl)-. The IUPAC name is 2-Bromoethylbenzene. Its EINECS registry number is 203-130-8. In addition, the formula is C₈H₉Br and the molecular weight is 185.08. This chemical is a colourless to yellow liquid that miscible with ether, benzene but insoluble in water. It may cause damage to health and should be stored away from oxidants. What's more, this chemical is used as pharmaceutical and pesticide intermediates, and it is also used for organic synthesis.

Physical properties about 2-Phenylethyl bromide are: (1)ACD/LogP: 3.09; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): 3.09; (4)ACD/LogD (pH 7.4): 3.09; (5)ACD/BCF (pH 5.5): 131.12; (6)ACD/BCF (pH 7.4): 131.12; (7)ACD/KOC (pH 5.5): 1141.38; (8)ACD/KOC (pH 7.4): 1141.38; (9)#Freely Rotating Bonds: 2; (10)Index of Refraction: 1.556; (11)Molar Refractivity: 43.53 cm³; (12)Molar Volume: 135.4 cm³; (13)Surface Tension: 37.8 dyne/cm; (14)Density: 1.366 g/cm³; (15)Flash Point: 89.4 °C; (16)Enthalpy of Vaporization: 43.83 kJ/mol; (17)Boiling Point: 220.5 °C at 760 mmHg; (18)Vapour Pressure: 0.167 mmHg at 25 °C.

Preparation of 2-Phenylethyl bromide: it is prepared by reaction of phenylethanol with hydrogen bromide. Firstly, phenylethanol is heated to 110 °C and hydrogen bromide is slowly passed into for refluxing. After reaction, the reaction mixture is cooled, washed with water, 10% sodium carbonate solution and water by turns. At last, product is obtained by drying with anhydrous potassium carbonate, vacuum distillation and collecting distillate at 97-99 °C. The yield is about 90%.

Uses of 2-Phenylethyl bromide: it is used to produce 1-phenethyl-piperidine by reaction with piperidine. The reaction occurs with solvent toluene and other condition of heating for 24 hours. The yield is about 36%.

2-Phenylethyl bromide is used to produce 1-phenethyl-piperidine by reaction with piperidine.
