Abstract: Process for the preparation of 2,6-dihydroxynaphthalene from 2,6-dialkylnaphthalenes, which are dissolved in an inert solvent and are oxidized at temperatures from 50.degree. to 150.degree. C. by means of oxygen or oxygen donors, in the presence of an alkali metal salt or alkaline earth metal salt of an organic carboxylic acid having 5 to 14 carbon atoms, to give the corresponding 2,6-dialkylnaphthalene dihydroperoxides, and the latter are subsequently hydrolysed.The process results in pure, easily isolatable products in a good yield. The process products according to the invention are valuable intermediates for, inter alia, dyes, plastics, synthetic fibres, polymeric liquid crystals or pharmaceuticals.

Abstract: Benzene or alkylbenzene (e.g. toluene) is alkylated with propylene to produce diisopropylbenzenes or isopropylalkylbenzenes, which in turn are selectively cracked to remove the 1,4-isomer. The resultant product, containing a high level of the 1,3-isomer, is then oxidized to 1,3-dihydroxybenzene or 3-alkylphenol (e.g. 3-methylphenyl) in significant yield.

Abstract: A portion of a stream obtained by the oxidation of an aryl tertiary alkane and containing primarily aralkyl tertiary monohydroperoxide, substantial amounts of aryl tertiary alkane, smaller amounts of keto aryl tertiary alkanols, aralkyl tertiary dialkanols and other by-products is subjected to a separation step wherein a fraction containing the greater part of the aryl tertiary alkane and at least some of the monohydroperoxide, and a fraction containing the keto aryl tertiary alkanol are separated from one another and the fraction containing the aryl tertiary alkane and the monohydroperoxide is returned to the oxidation reaction.

Abstract: An improved method for separating para-dialkylbenzene monohydroperoxide from crude solid para-dialkylbenzene dihydroperoxide which comprises treating the solid dihydroperoxide with a liquid hydrocarbon to form a mixture, heating the mixture to a temperature of at least about 60.degree. C., cooling the mixture to below about 30.degree. C. and filtering or otherwise physically separating the solid dihydroperoxide.
