Abstract: The novel borane-1,4-thioxane is synthesized by adding the calculated quantity of diborane to 1,4-thioxane. It is a stable liquid at 25.degree. C. The neat liquid is approximately 8.0 M in borane. The product, in spite of the additional oxygen atom in the ring, exhibits the desirable hydroborating and reducing action of borane-methyl sulfide. However, it possesses a major advantage over the latter in that the donor component, 1,4-thioxane, in contrast to methyl sulfide, is readily soluble in water and can be washed out of typical reaction mixtures. This greatly facilitates the synthetic applications of borane-1,4-thioxane over borane-methyl sulfide.

Abstract: A process for the treatment of a waste liquid containing boron compounds and organic compounds, such as resulting from the oxidation of paraffins with oxygen in the presence of boron compounds, includes combusting the waste liquid in a furnace at a temperature higher than 1000.degree. C. in the presence of a large amount of steam. The combustion gas may be introduced into a heat recovery zone, preferably a boiler, to recover the heat thereof and then into a contacting vessel to bring same into contact with water and to recover the boron components contained in the gas. Since substantially all the boron components contained in the combustion gas are present in the form of gaseous metaboric acid, there is caused no deposition of boron oxide onto the interior walls of the combustion furnace or gas passages in the boiler.

Abstract: The invention relates to alkylborane complexes with aromatic amines of the formula: ##STR1## in which R.sup.1 and R.sup.2 are the same or different (1-4C)-alkyl radicals, or together with the adjacent nitrogen atom are morpholino, piperidino or pyrrolidino radicals; R.sup.3 and R.sup.4 are independently selected from hydrogen, (1-4C)-alkyl, (1-4C)-alkoxy, di-(1-4C)-alkylamino, morpholino, piperidino and pyrrolidino; thexyl stands for 1,1,2-trimethylpropyl; and n is the integer 1 when R.sup.3 and R.sup.4 are other than nitrogen containing radicals, or the integer 1 or 2 when one of R.sup.3 and R.sup.4 is a nitrogen containing radical, or the integer 1, 2 or 3 when both R.sup.3 and R.sup.4 are nitrogen containing radicals.The complexes are more stable than thexylborane tetrahydrofuran complex, but are sufficiently reactive to be valuable as hydroborating and reducing agents.

Abstract: An oxidizable hydrocarbon is oxidized in a reaction zone at elevated temperature in the presence of a liquid reaction medium by introducing the hydrocarbon and a feed stream containing molecular oxygen to the reaction zone under conditions sufficient to oxidize at least a portion of the hydrocarbon; withdrawing at least a portion of the liquid reaction medium from the reaction zone; passing at least a portion of the withdrawn liquid reaction medium to an oxygen injection zone located external to the reaction zone; contacting the liquid in said oxygen-injection zone with a gas stream containing molecular oxygen under conditions sufficient to form a two-phase gas/liquid mixture; and passing said two-phase gas/liquid mixture to the reaction zone as the feed of molecular oxygen thereto.

Abstract: A method for the recovery of boron compounds from waste streams containing boric acid and combustible organic materials in water by incineration of the combustible organic materials and dehydration of the boric acid to boric oxide. Quenching of the boric oxide, depending upon temperature and water content, yields orthoboric and/or metaboric acids in vapor phase and polyboric acid in liquid phase which is cooled along with the products of the combustion of the organic materials and, in the presence of water, converted to a mixture of boric acids in solid and liquid phase leaving the products of combustion in vapor phase. The mixture of boric acids is then separated from the products of combustion.
