ABSTRACT:
Processes for the recovery of phenol values as cyclohexanol from the purification residue obtained in the amine purification of phenol. The recovery of phenol values may be effected by hydrogenation in the presence of a nickel catalyst and distilling the hydrogenation product to obtain cyclohexanol. Alternatively, the purification residue may be distilled and the distillate hydrogenated to produce a hydrogenation product from which cyclohexanol may be recovered by a second distillation.
