    摘要: A process for selectively producing ethyl mercaptan from a reactant mixture such as, for example, refinery fuel gas mixture is provided which comprises contacting, in the presence of a catalyst such as, for example, oxides of cobalt and molybdenum supported on aluminum, the reactant mixture with hydrogen sulfide wherein the reactant mixture contains ethylene and at least one other olefin such as, for example, propylene. The reactant mixture can also contain other components such as, for example, hydrogen, ethane, methane, propylene, or propane, or mixtures thereof.

    摘要: A process for preparing a poly(arylene sulfide) and copolymer thereof from a poly(arylene sulfide disulfide) is provided which comprises contacting the poly(arylene sulfide disulfide) with a polyhalo-substituted cyclic compound having unsaturation between adjacent ring carbon atoms and having halogen atoms attached to the ring carbon atoms in a polar organic compound and a basic compound at an elevated temperature. Alternatively, the poly(arylene sulfide disulfide) can be substantially dissolved in the polar organic solvent at elevated temperature to form fragments which can be contacted with the polyhalo-substituted cyclic compound in a polar organic compound and a basic compound at an elevated temperature. The fragments also can be isolated, recovered and then contacted with the polyhalo-substituted cyclic compound in a polar organic compound and a basic compound at an elevated temperature.
