Abstract: 2-(1-cyclohexenyl)-cyclohexanone is prepared by condensation of cyclohexanone using a macro-porous ion exchange resin such as Lewatite SPC 118 W or equivalent at temperatures not exceeding 125 .degree.C., provided that the conversion reaction is maintained below 50 %, preferably below 35 %. The reaction mixture is distilled at atmospheric pressure in the absence of the ion exchange resin and the desired product is recovered in substantially high yields generally greater than 95 %.

Abstract: PROCESS FOR RECOVERY OF ORTHO-PHENYLPHENOL A process for purifying ortho-phenylphenol which is admixed with ortho-cyclohexylphenol, by treating the mixture with an alkaline solution containing less than one mole equivalent of base per mole of ortho-phenylphenol in said mixture; the alkaline solution is extracted and ortho-phenylphenol is recovered from the aqueous phase by acificiation and extraction with subsequent isolation of the ortho-phenylphenol, which contains less than 5% (by weight) ortho-cyclohexylphenol.
