Abstract: A method and apparatus are provided for analysis of a sample of matter for multiple organic constituents and elemental sulfur in a single process. The method involves passage of a fluid sample through a first separations zone for retention of a first organic constituent, passage through a second separations zone for separation of the remaining organic constituents and sulfur, and quantitative determination of each constituent of interest including elemental sulfur.

Abstract: A process is provided for the recovery of one or more useful products including fertilizer, salt, and/or purified process water from brines. The source of the brines can be oil field wastes, seawater, or other inland brine sources. Phosphoric acid is initially added to the brine followed by addition of ammonia or a basic form of potassium. The resulting precipitate is useful as a fertilizer. The remaining salt in the brine may then be removed and recovered along with purified process water.

Abstract: The geochemical oil prospecting method is disclosed in which a crude oil sample is analyzed for the presence of distinctive patterns of aromatic sulfur compounds which are indicative of the petroleum source rock type. Using relative proportions of benzothiophenes, dibenzothiophene, isomeric methyl dibenzothiophenes, dimethyl- and trimethydibenzothiophenes a crude oil can be identified as having a carbonate or siliciclastic source. The information obtained can be used in combination with geological and seismic studies to determine potential oil locations.

Abstract: Double bond isomerization and disproportionation of olefins is obtained by contact with a catalyst in a single-stage composition containing a support, uranium, and at least one of tungsten, molybdenum, or rhenium.

Abstract: An olefinic hydrocarbon is isomerized utilizing a catalyst system consisting essentially of a mixture of a nickel complex of the formula (R.sub.3 P).sub.2 NiX.sub.2 and an alkali metal borohydride.

Abstract: A compound of vanadium or niobium complexed with NO and a selected complexing agent.

Abstract: Structural modification of olefinically unsaturated alcohols is achieved by contacting the unsaturated alcohol under reaction conditions with a catalytic amount of a catalyst composition comprising a ruthenium hydride complex of tertiary phosphine ligands.

Abstract: An olefinic hydrocarbon is isomerized utilizing a catalyst system consisting essentially of a mixture of a nickel complex of the formula (R.sub.3 P).sub.2 NiX.sub.2 and an alkali metal borohydride.

Abstract: Dinitrosyldihalo complexes of molybdenum or tungsten are produced from (1) an oxytetrahalide of molybdenum or of tungsten, (2) an alkali metal nitrite, (3) a reducing agent which is metallic iron or a borohydride of sodium, potassium, rubidium, or cesium, (4) a ligand-forming compound, (5) in an aprotic diluent.

Abstract: At least one unsaturated alcohol is contacted with at least one molybdenum-containing compound under reaction conditions suitable to convert at least a portion of the at least one unsaturated alcohol to at least one conjugated diene, the at least one unsaturated alcohol being selected from the group consisting of .alpha.-olefinic alcohols and .beta.-olefinic alcohols, the at least one molybdenum-containing compound being selected from the group consisting of molybdenum .beta.-diketonates and molybdenum (II) carboxylates.
