摘要:
Novel peroxide compounds and the use thereof. In particular, the present invention concerns .beta.-hydroxycyclopentylperoxide compounds of the general formula: ##STR1## wherein R.sub.1 represents hydrogen or an organic residue of 1 to 9 carbon atoms. These novel peroxide compounds are useful as an intermediate in the production of glutaraldehydes.
摘要:
A method of preparing 1-phenyl cyclohexylhydroperoxide by contacting a mixture of cyclohexylbenzene, an alkali or alkaline earth metal salt of cumene hydroperoxide, and an alkali or alkaline earth metal salt of phenol or a substituted phenol with an oxygen containing gas under effective reaction conditions of temperature and pressure.
摘要:
In the preparation of tertiary-butyl hydroperoxide by the direct oxidation of isobutane, the production of tertiary-butyl hydroperoxide, expressed as the quantity of the compound prepared per unit of reactor volume per unit of time, is enhanced by conducting the oxidation in a dense, supercritical phase reaction mixture at a temperature in excess of the critical temperature of the mixture, at a pressure in excess of the critical pressure of the mixture, and under conditions relating to composition of the mixture.
摘要:
Organic hydroperoxides are prepared by reacting an organic compound with oxygen in the presence of a novel catalyst comprising metallic silver supported upon an inorganic support selected from the oxides and carbonates of metals of Groups IIa, IIb, IIIb, and IVb.
摘要:
A process for the continuous production of .beta.-isopropylnaphthalene hydroperoxide comprising oxidizing an isopropylnaphthalene mixture containing .alpha.- and .beta.-isopropylnaphthalene isomers with molecular oxygen or a molecular oxygen containing gas in an oxidation zone and recycling unreacted ispropylnaphthalene recoverd after the oxidation to the oxidation zone, in which the oxidation is carried out by controlling the .alpha.-isopropylnaphthalene content in the isopropylnaphthalene mixture continuously fed to the oxidation zone to about 15% by weight or less.
摘要:
Process, and resulting product, for improved hydroperoxidation of branched alkanes of at least 4 carbon atoms, especially useful in preparation of isoprene from isopentane; comprising the substantial elimination of acetic acid and similar by-products in the hydroperoxidation reaction which are harmful to the yield of the desired hydroperoxides; all of which is achieved by at least one washing between at least two successive oxidizing reactors. The wash solution may be just water or advantageously a pre-saturated aqueous solution containing the oxidation products which are desired not to be extracted from the organic phase of the reaction medium.
摘要:
The present invention relates to the manufacture of beta-isopropylnaphthalene hydroperoxide, an intermediate product in the manufacture of beta-naphthol.
摘要:
Normally liquid peroxidic poly(perfluorooxyalkylene) compositions comprising a mixture of peroxidic poly(perfluorooxyalkylene) compounds, derivatives of the poly(perfluorooxyalkylene) compositions comprising a mixture of non-peroxidic polyfluoropolyether compounds, and derivatives of the polyfluoropolyether compositions comprising functional and non-functional derivatives of the polyfluoropolyether compositions are provided. Each peroxidic poly(perfluorooxyalkylene) compound comprises a backbone of randomly distributed perfluorooxyalkylene units, represented by the formulas --CF.sub.2 O--, ##STR1## and --O--, which when bonded to and --O-- of any of the perfluorooxyalkylene units, forms a peroxy group, --O--O--, which imparts the peroxidic characteristics to the material, and backbone-pendant perfluoroalkoxy groups or perfluoroalkoxy groups substituted with one or more ether oxygen atoms, the terminal ether oxygen atoms of which are bonded to carbon atoms of the ##STR2## backbone units.
摘要:
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-methylphenol) in significant yield.
