Abstract: An apparatus and method for purifying boron trichloride by removal of phosgene. In accordance with the invention, phosgene is photolytically decomposed into carbon monoxide and chlorine and liquid vapor phase in equilibrium with one another and in solution with the boron trichloride. This equilibrium is disturbed preferably by sparging a vapor stream that rises through the boron trichloride and is composed of the substance, such as nitrogen, to disturb the equilibrium and thereby cause the carbon monoxide and chlorine to be carried out of solution and collect in the overhead space. The decomposition product of chlorine and carbon monoxide can then be removed from the vapor space so that the carbon monoxide and chlorine does not recombine and contaminate the boron trichloride with phosgene.

Abstract: Method of and apparatus for non-equilibrium chemical kinetic separation of deuterium from hydrogen are described wherein hydrogen with its normal abundance of deuterium and an appropriate reactant, bromine, are supplied to a deuterium reaction vessel wherein they are vibrationally excited by, for example, being exposed to a volumetrically scalable ionizing-sustainer electrical discharge effective to provide vibrational excitation of the H.sub.2 and HD following which selective intermolecular vibration-vibration energy pumping occurs giving conditions effective to produce an HBr/DBr product mixture. The ionizing-sustainer discharge is effective to generate vibrational excitation from which follows chemical reactions that produce DBr and HBr at such relative rates that the mixture is enhanced in deuterium content relative to said content of the entering hydrogen stream. For the production of heavy water, the DBr and HBr are then dissolved in water. This water is then reacted with oxygen to chemically separate the bromine and the bromine is removed to leave water enriched in deuterium. Additional DBr/HBr product mixture is then dissolved in this deuterium enriched water and the process repeated to produce water having the deuterium content of the product DBr/HBr.

Abstract: SUBSTRATE MEMBER IS HEATED TO A SUITABLE TEMPERATURE IN EXCESS OF 1200*C. IN A DEPOSITION CHAMBER PARTIALLY EVACUATED TO SUBATMOSPHERIC PRESSURE. DIBORANE GAS IS REACTED WITH AMMONIA GAS WITH A TEMPERATURE RANGE OF 200-300*C. TO PRODUCE AN INTERMEDIATE GASEOUS REACTION PRODUCT. THE INTERMEDIATE GASEOUS REACTION PRODUCT IS CAUSED TO FLOW ACROSS THE HEATED SUBSTRATE TO CAUSE DECOMPOSITION OF THE GASEOUS REACTION PRODUCT WITH RESULTANT DEPOSITION OF A RELATIVELY THICK DEPOSIT OF ISOTROPIC BORON NITRIDE ONTO THE HEATED SUBSTRATE. IN A PREFERRED EMBODIMENT, THE SUBSTRATE MEMBER IS TUBULAR AND COAXIALLY ALIGNED WITH A GASEOUS STREAM OF THE INTERMEDIATE GASEOUS REACTION PRODUCT SUCH THAT THE GASEOUS STREAM FLOWS THROUGH THE INTERIOR OF THE TUBULAR SUBSTRATE FOR DEPOSITING THE BORON NITRIDE ON THE INTERIOR SURFACES OF THE TUBULAR SUBSTRATE. THE DIBORANE GAS IS INTRODUCED IN A RELATIVELY INERT CARRIER GAS STREAM IN A CONCENTRATION OF MORE THAN 50,000 PARTS PER MILLION DIBORANE GAS. THE SUBATMOSPHERIC PRESSURE WITHIN THE DEPOSITION CHAMBER IS PREFERABLY LESS THAN 3/10 OF AN ATMOSPHERE SUCH THAT THE CONCENTRATION OF THE INTERMEDIATE GASEOUS REACTION PRODUCT IS RELATIVELY HIGH AND THE PROBABILITY THAT THE REACTION PRODUCT WILL REACH THE INTERIOR WALL OF THE SUBSTRATE IS RELATIVELY HIGH TO FACILITATE RELATIVELY RAPID GROWTH RATES OF THE BORON NITRIDE AND EFFICIENT UTILIZATION OF THE INTERMEDIATE GASEOUS REACTION PRODUCT.

Abstract: Methods and reaction systems are disclosed that are adapted for forming crystallites having novel crystal habits and/or morphologies compared to conventional crystallites of the same chemical composition. The methods and reaction systems involve chemical reactions between at least two reactant compounds occurring in a liquid (or gel) that form insoluble crystallite products. At least one of the reactants is rendered soluble in a solvent in which the reactant is not normally soluble by adding an agent that forms soluble molecular complexes of the agent and the reactant. The complexing agent not only facilitates dissolution of the reactant in the solvent but also plays a role in how the faces of crystals comprising the crystallite product are enlarged during formation of the product. Products having such altered crystallite structure have a number of possible uses.

Abstract: A method is provided for removing ammonia from the sour water stream of a coal gasification process. The basic steps comprise stripping the ammonia from the sour water; heating the stripped ammonia to a temperature from between 400.degree. to 1,000.degree. F; passing the gaseous ammonia through a reactor containing a sulfided catalyst to produce elemental hydrogen and nitrogen; and scrubbing the reaction product to obtain an ammonia-free gas. The residual equilibrium ammonia produced by the reactor is recycled into the stripper. The ammonia-free gas may be advantageously treated in a Claus process to recover elemental sulfur. Iron sulfide or cobalt molybdenum sulfide catalysts are used.

Abstract: This invention relates to the preparation of alkali metal hydrides and of alkali metal aluminum dihydrocarbon dihydrides and in particular to such compounds of sodium, potassium or lithium having in the case of the dihydrocarbon compounds hydrocarbon radicals containing from 2 to about 30 carbon atoms per radical. Such dihydrocarbon materials, as typified by sodium aluminum diethyl dihydride, and by the potassium or lithium counterparts, either singly or in mixtures with respect to alkali metals and hydrocarbon groups, are soluble and useful in inert aromatic hydrocarbon solutions and have excellent mild reducing properties for various functional groups such as carbonyl groups in various organic compounds. The alkali metal hydrides are useful in many known ways such as in condensation and alkylation reactions and as chemical intermediates such as in the preparation of the alkali metal aluminum dihydrocarbon dihydrides.
