    • A method for preparing molybdenum and sulfur containing compounds of the general formula X.sub.2 Mo.sub.2 S.sub.12.yH.sub.2 O, where X is a cation selected from the group consisting of Na.sup.+, K.sup.+, R.sub.4 N.sup.+, R.sub.3 NH.sup.+, R.sub.2 NH.sub.2.sup.+, RNH.sub.3.sup.+, NH.sub.4.sup.+, R.sub.4 P.sup.+, R.sub.4 As.sup.+,(R.sub.3 P).sub.2 N.sup.+, R is a C.sub.1 -C.sub.30 alkyl, C.sub.6 -C.sub.30 aryl, C.sub.7 -C.sub.30 aralkyl or C.sub.2 -C.sub.30 alkoxyalkyl group and mixtures thereof, and y is from 0 to 2. The method comprises preparing a sulfide solution that contains from about 9 wt. % to about 13 wt. % sulfide sulfur; contacting the solution with elemental sulfur and a hydroxide; adding a molybdenum compound for a time and at a temperature sufficient to form a reaction mixture and a precipitate; separating the precipitate; and contacting the remaining reaction mixture with additional sulfide solution to form (NH.sub.4 ).sub.2 Mo.sub.2 S.sub.12.yH.sub.2 O. When compounds containing cations other than NH.sub.4.sup.+ are to be produced, the (NH.sub.4).sub.2 Mo.sub.2 S.sub.12.yH.sub.2 O is contacted with a cation exchange compound containing a desired substitute cation selected from above and an anion selected from the group consisting of Cl.sup.-, Br.sup.-, F.sup.-, I.sup.-, BF.sub.4.sup.-, PF.sub.6.sup.-, OH.sup.-, BR.sub.4.sup.- where R is a C.sub.1 -C.sub.30 alkyl, C.sub.6 -C.sub.30 aryl, C.sub.7 -C.sub.30 aralkyl or C.sub.2 -C.sub.30 alkoxyalkyl group, and mixtures thereof, in the presence of a solvent and for a time and at a temperature sufficient to form X.sub.2 Mo.sub.2 S.sub.12.yH.sub.2 O, where X is other than NH.sub.4.sup.+.

    • An improved hydroconversion process for carbonaceous materials wherein an ammonium or hydrocarbyl substituted ammonium salt of a metal-sulfur analog of cubane having an anion with a core structure of M.sub.4 S.sub.4 is used as a catalyst precursor. In the general formula, M may be the same or a different metal having hydrogenation catalytic activity when used as a sulfide and capable of occupying one or more vertices in a cubane structure. The metal may also have the capability of bridging one or more such structures. The improved process is effective for both normally solid and normally liquid carbonaceous materials and for carbonaceous materials which are either solid or liquid at the conversion conditions. The hydroconversion will be accomplished at a temperature within the range from about 500.degree. to about 900.degree. F., at a total pressure within the range from about 500 to about 7000 psig and at a hydrogen partial pressure within the range from about 400 to about 5000 psig.
    • 用于含碳材料的改进的加氢转化方法,其中使用具有核心结构为M4S4的阴离子的立方烷金属 - 硫类似物的铵或烃基取代的铵盐作为催化剂前体。 在通式中,当用作硫化物并且能够占据立方体结构中的一个或多个顶点时,M可以是相同或不同的具有氢化催化活性的金属。 金属也可以具有桥接一个或多个这样的结构的能力。 改进的方法对于常规固体和常规含碳材料以及在转化条件下为固体或液体的碳质材料都是有效的。 加氢转化将在约500至约900°F范围内的温度下进行,总压力范围为约500至约7000psig,氢分压为约400至约 5000 psig
