Triphenylmethanol Specification

Triphenylmethanol is also known as Trityl alcohol, Triphenylcarbinol, 76-84-6, Methanol, triphenyl-, Tritanol, Triphenylmethyl alcohol, triphenylmethan-1-ol. With the Molecular Formula C19H16O, it is an organic compound and a white crystalline solid that is insoluble in water and petroleum ether, but well soluble in ethanol, diethyl ether, and benzene. It reacts with acetyl chloride to give triphenylmethyl chloride.

Physical properties about Triphenylmethanol are: (1)ACD/LogP: 3.836; (2)ACD/LogD (pH 5.5): 3.84; (3)ACD/LogD (pH 7.4): 3.84; (4)ACD/BCF (pH 5.5): 484.72; (5)ACD/BCF (pH 7.4): 484.71; (6)ACD/KOC (pH 5.5): 2909.88; (7)ACD/KOC (pH 7.4): 2909.86; (8)#H bond acceptors: 1; (9)#H bond donors: 1; (10)#Freely Rotating Bonds: 4; (11)Index of Refraction: 1.622; (12)Molar Refractivity: 81.072 cm3; (13)Molar Volume: 230.289 cm3; (14)Polarizability: 32.14 10-24cm3; (15)Surface Tension: 46.4389991760254 dyne/cm; (16)Density: 1.13 g/cm3; (17)Flash Point: 168.744 °C; (18)Enthalpy of Vaporization: 66.255 kJ/mol; (19)Boiling Point: 379.999 °C at 760 mmHg

Preparation of Triphenylmethanol: The preparation of triphenylmethanol from methyl benzoate or benzophenone and bromobenzene is a common laboratory experiment for teaching the Grignard reaction. An alternative starting material is diethyl carbonate.
