Abstract: It has been found that unexpectedly high yields of a high purity product can be obtained when substituted p-quinones are prepared by oxidation, using a molecular oxygen-containing gas, of the corresponding phenols in an inert solvent having a dipole moment of at least 2.7 and in the presence of a salcomine catalyst.

Abstract: At least one of a polycyclic phenol, a polycyclic alcohol and a polycyclic ketone is produced under hydrogenation conditions using a nickel oxide/manganese oxide/magnesium oxide catalyst by subjecting at least one of a monocyclic ketone, a monocyclic alcohol and a monocyclic phenol to said conditions and said catalyst.

Abstract: Compounds in which 2,6-di(t-butyl)phenol is substituted in the 4 position by an optionally substituted phenyl group have valuable pharmacological activity as anti-inflammatory agents.

Abstract: A process for the hydroxylation of phenols and phenol ethers in the nucleus with hydrogen peroxide wherein a phenol or a phenol ether is reacted at the start of the reaction with substantially anhydrous hydrogen peroxide and wherein the reaction is carried out in the presence of a strong acid.

Abstract: Hydroxy, alkoxy and acyloxy ethynylbenzene compounds and their derivatives which are useful for the treatment for the relief of inflammation, pain and fever.

Abstract: An organic hydroperoxide is hydrolyzed by acid-catalysis in a reaction medium comprising essentially a mixture of a polar solvent, e.g. a low boiling, low molecular weight alcohol and/or sulfolane and phenol. Specifically cyclohexanone and phenol are obtained from cyclohexylbenzene hydroperoxide.

Abstract: Haloloweralkyl ethynylbenzene compounds and their derivatives which are useful for the treatment for the relief of inflammation, pain and fever.

Abstract: Aromatic aldehydes wherein the aldehyde group is directly attached to the aromatic ring are oxidized directly to phenolic compounds in the vapor phase. Tar and carbonaceous product formation are minimized by the method of preheating and mixing the reactants and by a rapid reaction temperature quench of the reaction mixture to below 0.degree. C. Mixing temperature is 300.degree.-350.degree. C. and reaction temperature is 400.degree.-600.degree. C. at 1-10 atmosphere pressure.

Abstract: The process of preparing diphenyl oxide from caustically hydrolyzing chlorobenzene, wherein phenol is a by-product, is improved by recycling the phenol. The improvement not only maximizes the yield of diphenyl oxide while minimizing the yield of phenol, but it also increases the yield of desirable by-products, such as phenylphenols and biphenylylphenyl ethers.

Abstract: A process for preparing o-phenylphenol by dehydrogenating at least one of cyclohexanone dimer and o-cyclohexylphenol in the presence of a catalyst, characterized in that the catalyst is one prepared by causing a metal oxide carrier to support at least one compound substantially producing platinum or palladium on the resulting catalyst, at least one compound substantially producing an alkali metal oxide on the resulting catalyst and at least one of hydrogen sulfide, organic sulfur compound and alkali metal sulfide, and heating the carrier at 300.degree. to 400.degree.
