Abstract: A process for oxygenating organic substrates such as aliphatic hydrocarbons has been developed. The process involves contacting the organic substrate with oxygen in the presence of a bicyclo imide promoter and a metal co-catalyst. The process is preferably carried out using sulfolane as the solvent. Optionally, the oxygenated product can be hydrogenated to give the corresponding alcohol which can optionally in turn be dehydrated to provide the corresponding olefin.

Abstract: Conductive fuel detergent compositions which posses not only the desirable characteristics of minimizing unwanted deposits on internal engine surface such as intake systems or port fuel injectors and exhibiting anticorrosion characteristics but also have conductive properties comprise quaternary succinimides which are characterized by having an oligomeric alkyl moiety on the succinimide ring. The additive may be prepared by condensing a (polyalkyl)succinic anhydride with a polyamino hydroxyalkyl quaternary ammonium salt, where the latter is formed by the reaction of a .OMEGA.-haloepoxide with a tertiary amine followed by reaction of the resulting product with a polyamine.

Abstract: A method of preparing p-aminodiphenylamines from diphenylamines is described whereby neither the N-nitrosodiphenylamine or the p-nitrosodiphenylamine need be isolated. The method rests on the discovery that alkali metal salts of p-nitrosodiphenylamines are soluble in non-aqueous organic solvent systems consisting of certain aromatic hydrocarbons and saturated aliphatic alcohols, and that such salts can be readily hydrogenated in their non-aqueous solution to the corresponding p-aminodiphenylamine.

Abstract: Sweetening of sour hydrocarbon feedstocks by contacting with an aqueous solution of a metal chelate as an oxidation catalyst in the presence of oxygen is hindered by the difficulty of recovering metal chelate. Extraction of the aqueous phase with a liquid secondary amine with low water solubility removes a main portion of the metal chelate, usually a mixture of polysulfonated cobalt phthalocyanines, from the aqueous phase, and subsequent recovery of the chelate from the amine extract enables a viable alternative to feed bed processes.

Abstract: The oxidation of cyanide under acid conditions using oxygen as the oxidizing agent can be effected under mild reaction conditions when certain metal chelates are used as catalysts. Especially effective chelates are metal phthalocyanines, particularly where the metal is vanadium or a member of the iron group metals. The oxidation can be effected homogeneously using water soluble metal chelates, or can be performed heterogeneously, especially in a continuous fashion using a packed bed reactor, by using suitable water-insoluble metal chelates, especially when supported on appropriate carriers.

Abstract: Continuous methylation of tetralin with methanol over several solid acid catalysts affords a mixture of 5-methyltetralin and 6-methyltetralin with selectivity of better than 65% at high conversions. Zeolite .beta. is a particularly effective catalyst insofar as it catalyzes the reaction at a temperature approximately 100.degree. C. lower than that required for silica-aluminas. However, the reaction temperature is quite sensitive to the concentration of methanol in the feedstock.

Abstract: The yellow pigments which result from reaction of the Monascus pigments monascorubrin and rubropunctatin with amines followed by reduction of the ring carbonyl moiety to an hydroxyl group have excellent properties for their use as food colorants. Yellow pigments made from amino acid esters, dipeptide esters, and amines of sugar alcohols have particular promise as desirable food colorants which are effective at levels which impart no objectionable taste to foods.

Abstract: Thin film composite membranes having as a permselective layer a film of a homopolymer of certain vinyl alkyl ethers are useful in the separation of various gases. Such homopolymers have a molecular weight of greater than 30,000 and the alkyl group of the vinyl alkyl monomer has from 4 to 20 carbon atoms with branching within the alkyl moiety at least at the carbon atom bonded to the ether oxygen or at the next adjacent carbon atom. These membranes show excellent hydrolytic stability, especially in the presence of acidic or basic gaseous components.
