Abstract: A process for the preparation of bromostyrenes which comprises aqueous alcoholic alkali dehydrohalogenation of a 1-haloethyl bromobenzene, a 2-haloethyl bromobenzene, or a 1-methyl-2-haloethyl brominated benzene in the presence of a phase transfer catalyst at a temperature of between about 0.degree. C. and about 150.degree. C. The bromostyrenes have the particular utility as a comonomer for the preparation of a co-polymer exhibiting a flame retardancy. Both bromostyrenes and brominated alpha-methyl styrenes are formed.

Abstract: Process for preparing cyclic amines by the reductive amination of saturated cyclic ketones. For example, cyclohexanone is reductively aminated to obtain N,N-dimethylcyclohexylamine.

Abstract: A process for the preparation of an ar-dibromostyrene which comprises aqueous alcoholic alkali dehydrobromination of 2-bromoethyl dibromobenzene in the presence of a phase transfer catalyst at a temperature of between about 0.degree. C. and about 150.degree. C. The ar-dibromostyrenes have the particular utility as a co-monomer for the preparation of a co-polymer exhibiting a flame retardancy.

Abstract: Dibromostyrene is stabilized against unwanted polymerization by incorporating therein a stabilizing amount of a phenylene diamine such as N,N,N',N'-tetramethylphenylene-p-diamine or N,N'-diethylphenylene-p-diamine.

Abstract: Dibromostyrene has a marked tendency to polymerize on storage. The induction period can be lengthened with the use of a stabilizing quantity of n-propylgallate. The induction period can be markedly prolonged when the gallate ester is admixed with phenothiazine, N,N,N',N'-tetramethyl-p-phenylenediamine, or 4-tert-butyl catechol.

Abstract: Dibromostyrene is stabilized against unwanted polymerization by incorporating therein a stabilizing amount of phenothiazine or a substituted phenothiazine such as 3,3'-dioctylphenothiazine. The phenolthiazine can be admixed with a dihydroxy aromatic compound such as 4-methyl catechol.

Abstract: Mixing dibromostyrene with a metal oxide such as zinc oxide lengthens the induction period before polymerization of dibromostyrene. Preferably, the dibromostyrene has low levels of 2-bromoethyldibromobenzene and tribromostyrene impurities.

Abstract: Lubricating oil adapted for use in diesel engines containing a sulfurized fatty acid ester of a polyhydric alkanol, e.g. sorbitan mono-ester of sulfurized oleic acid.

Abstract: Ethylene/C.sub.3-12 .alpha.-monoolefin copolymers having an average molecular weight of about 10,000-1,000,000 containing about 1-10 pendent amide and/or ester groups per each 10,000 molecular weight are effective ashless dispersants and impart viscosity lift to lubricating oils. They are made by the permanganate oxidation of ethylene/C.sub.3-12 .alpha.-monoolefin/non-conjugated diene terpolymers which oxidizes the residual olefinic double bond of the diene unit to a carboxylic acid which is amidated and/or esterified.

Abstract: Fuel induction systems of internal combustion engines are cleansed by operating the engine on a gasoline containing a detergent amount of the condensation product of phenol, and preferably a high molecular weight alkylphenol, an aldehyde, and an amine having a H--N< group. Effectiveness is improved, especially when using a large amount of the detergent composition or when using the detergent composition with water intolerant gasolines, by inclusion of a demulsifier containing an aryl sulfonate, a polyether glycol, and an oxyalkylated phenol formaldehyde resin.The concentrates of this invention also include one or more alcohols of about 4 to about 10 carbon atoms, an aromatic solvent, and a corrosion inhibitor.This invention also comprises gasolines containing these concentrates; the concentrate being present in a small amount that confers carburetor detergency properties to the gasoline.
