摘要
A process for the purification of 1,1-diphenylethane with good fragrance quality. The product is produced by first subjecting the distillation residue from ethylbenzene production to distillation, then treating the distillate with sulfuric acid, separating the sulfuric acid phase, washing the oil phase with an alkali metal hydroxide solution and water, and subjecting the oil phase thus obtained to a second distillation.
