white to light yellow crystal powde | [Uses]
1,2-Diphenylethane is used as solvent for nitro fibre and in synthesis of other organic chemical products. | [Definition]
ChEBI: A diphenylethane that is the 1,2-dihydro derivative of stilbene. | [Preparation]
1,2-Diphenylethane is synthesized by the action of benzyl chloride with sodium metal. Or from the reaction of benzyl chloride in the presence of copper, or from the hydrogenation of benzoin in the presence of nickel. | [Synthesis Reference(s)]
