Abstract: Electrically conducting polyacetylene compositions are described having incorporated therein a fluorine-containing peroxide, such as FSO.sub.2 --O--O--SO.sub.2 F. Preferred compositions exhibit novel metal-like conductivity at temperatures above about 150.degree. K., and specific conductivities above about 10.sup.2 ohm.sup.-1 -cm.sup.-1 at room temperature, as measured by the standard four-probe method. A process for producing the compositions is also described in which polyacetylene is contacted with the peroxide, preferably in an inert liquid solvent at low temperatures.

Abstract: An aqueous composition for inhibiting the corrosion of metals placed therein is described. The composition comprises a non-oxidizing acid, and, as a corrosion inhibitor, an effective amount of a 3-di(higher)alkylamino-3-phenylprop-1-yne.

Abstract: A corrosion inhibitor for aqueous solutions of mineral acids consisting essentially of the reaction product obtained by the catalytic ethynylation of a dialkylamine, a substituted benzaldehyde and acetylene, said reaction product being a complex material which contains predominately a 3-dialkylamino-3-(substituted phenyl) prop-l-yne.

Abstract: An improved process is described for producing hydrogen from carbon monoxide and water in which carbon monoxide is contacted under homogeneous conditions with an alkaline aqueous liquid phase containing a soluble rhodium-containing catalyst at a reaction temperature from about 100.degree. to 300.degree. C. and at a reaction pressure from about 1 to 300 atmospheres in the presence of a saturated paraffinic water-soluble alcohol.

Abstract: An improved process is described for converting methanol to ethanol in which a mixture of methanol, liquid water and a Group VIII metal catalyst and a basic inorganic compound is contacted with an atmosphere of carbon monoxide at a temperature of about 240.degree. to 280.degree. C and a pressure of about 3,000-5,000 psi gauge. Good yields and selectivities of ethanol are obtained eliminating the necessity of using gaseous hydrogen or steam as starting materials, as required in prior art processes.

Abstract: The invention provides a cyclic process for recovering copper from sulfide ores containing copper and iron which comprises reacting the sulfide ore with sulfur dioxide gas at a temperature of at least about 500.degree. C. to form elemental sulfur, removing the elemental sulfur, reacting the residual solids with concentrated sulfuric acid at a temperature of about 180.degree. to 500.degree. C. to form copper sulfate and sulfur dioxide gas, recycling the sulfur dioxide gas for reaction with additional ore, roasting the remaining solids at a temperature of about 400.degree. C. to 900.degree. C., leaching the roasted solids with an aqueous solution to solubilize the copper sulfate and recovering copper from the solubilized copper sulfate. In another embodiment of the invention, the roasting step is eliminated by removing magnetite from the solids remaining after removal of the elemental sulfur.
