1,1-DIPHENYLETHANOL Chemical Properties,Usage,Production

Chemical Properties

white to off-white powder or needles

Uses

1,1-Diphenylethanol was used to study the ESR spectra of the spiro-cyclohexadienyl intermediate in the alkoxyl radicals.

General Description

The H-bonds in 1,1-diphenylethanol were studied by means of infrared (IR) absorption spectra.

Purification Methods

Crystallise 1,1-diphenylethanol from n-heptane and/or distil it under vacuum. The benzoyl derivative has m 115o and the phenylurethane has m 119o. [Bromberg et al. J Am Chem Soc 107 83 1985, Beilstein 6 H 685, 6 I 330, 6 II 639, 6 III 3395, 6 IV 4713.]
