Abstract: Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are transhalogenated with fluorine by reaction with anhydrous hydrogen fluoride in an inert solvent, e.g., xylene, methylene chloride, in a manner such that said anhydrous hydrogen fluoride is added to said phosphorus compound at a rate such that said anhydrous hydrogen fluoride reacts with said phosphorus compound without the accumulation of an amount of unreacted anhydrous hydrogen fluoride which is sufficient to cause substantial decomposition of the desired fluorophosphorus product. A catalytic amount of a pyridine-type compound may optionally included in the reaction.

Abstract: Mono-ar-tert-butyl toluenediamine is selectively made by heating a mixture of toluenediamine and an aluminum halide of the formula R.sub.n AlX.sub.3-n or R.sub.3 Al.sub.2 X.sub.3 wherein n is 0, 1 or 2 and R is an alkyl containing 1-10 carbon atoms to 150.degree.-225.degree. C. and reacting the mixture with isobutylene at 500-300 psig until the yield of mono-ar-tert-butyl toluene is at or near maximum. Minor amounts of di-tert-butyl toluenediamines which form and are difficult to separate can then be lowered by venting the reaction and continuing to heat at about 130.degree.-200.degree. C. until the di-tert-butyl components are decreased to the desired level forming additional mono-ar-tert-butyl toluenediamine.

Abstract: Detergent bars suitable for use as toilet soaps are made by mixing an effective amount of a trialkylamine oxide dihydrate in a detergent bar formulation.

Abstract: Phosphorus compounds having at least one chlorine, bromine or iodine bonded directly to phosphorus are transhalogenated with fluorine by reaction with anhydrous hydrogen fluoride in an inert solvent, e.g., xylene, methylene chloride, in a manner such that said anhydrous hydrogen fluoride is added to said phosphorus compound at a rate such that said anhydrous hydrogen fluoride reacts with said phosphorus compound without the accumulation of an amount of unreacted anhydrous hydrogen fluoride which is sufficient to cause substantial decomposition of the desired fluorophosphorus product.

For example, soluble high molecular weight phosphonitrillic chloride can be made by heating the aforementioned trimer at 220.degree.-270.degree. C. in the presence of 5-1000 ppm of AlCl.sub.3.

Abstract: Mono- and di-lower alkylamines, e.g. methylamine or dimethylamine, are alkylated by reaction with C.sub.8-22 alcohol in the presence of hydrogen at a temperature of about 150.degree.-275.degree. C. in contact with a copper-zinc-alkaline earth metal base containing catalyst (e.g., CuO-ZnO-Ba(OH).sub.2) while removing water formed in the reaction.

Abstract: Alkylamines such as methylamine and dimethylamine react with alcohols and aldehydes at 150.degree.-275.degree. C. in the presence of hydrogen and a catalyst initially consisting essentially of (1) a copper compound selected from copper carbonate, copper oxide, copper hydroxide or mixtures thereof, (2) a zinc compound selected from zinc carbonate, zinc oxide, zinc hydroxide or mixtures thereof and (3) a metal compound selected from carbonates, oxides and hydroxides of a Group IIA metal and mixtures thereof at least one of said copper compound and zinc compound being a carbonate.

Abstract: 3,5-dialkyl-4-hydroxybenzyl-substituted benzene compounds are made by reacting 2,6-dialkyl-4-methoxymethyl phenols with a benzene compound having an unsubstituted nuclear position in an inert solvent and in the presence of sulfuric acid catalyst while distilling methanol by-product from the reaction mixture as it forms.

Abstract: Tert-amine oxides that are substantially free of nitrosamines are made by reacting a tert-amine, e.g., dodecyl dimethylamine, with aqueous hydrogen peroxide in the presence of the synergistic combination of (a) ascorbic acid and (b) a promoter formed from carbon dioxide.

Abstract: 3,5-dialkyl-4-hydroxybenzyl-substituted benzene compounds are made by reacting 2,6-dialkyl-4-methoxymethyl phenols with a benzene compound having an unsubstituted nuclear position in an inert solvent and in the presence of an organic sulfonic acid catalyst while distilling methanol by-product from the reaction mixture as it forms.

Abstract: BF.sub.3 is removed from a promoted BF.sub.3 catalyzed olefin oligomer reaction product by contacting the reaction product with either solid or aqueous KF to form a solid KBF.sub.4 precipitate. Solid NaF or NH.sub.4 F can also be used.

Abstract: A continuous process for the extraction of bromine from a bromide-rich brine in high efficiency while dramatically reducing the steam requirement for the distillation by operating a contact tower under vacuum. The contact tower is designed to operate near the boiling point of the feed brine so that only stripping steam is needed to remove elemental bromine from the brine.

Abstract: Vinyl-olefins are converted to vinylidene olefin dimers at a selectivity of at least 85 mole percent by reacting a mixture of dry vinyl-olefin containing 0.001-0.04 moles of trialkyl aluminum per mole of initial vinyl-olefin at a temperature in the range of about 100.degree.-140.degree. C. for a time sufficient to convert at least 80 mole percent of the initial vinyl-olefin to a different material.

These concentrated solutions offer large freight savings in shipping the amine oxides to remote locations.
