Abstract: Method for the production of branched chain esters comprising contacting methanol and/or dimethyl ether and carbon monoxide with zinc iodide at a temperature of from about 180.degree. C. to 450.degree. C. Improved selectivity to methyl pivalate is obtained by incorporating ethylene, propylene and/or isobutylene into the reaction mixture.

Abstract: Method for the reaction of an olefin comprising contacting an olefin and a reactant selected from methanol, dimethyl ether, or mixtures thereof, with zinc iodide, zinc bromide, or mixtures thereof, at a temperature of from about 180.degree. C. to 450.degree. C.

Abstract: Method for the conversion of butadiene (1,3) comprising contacting butadiene (1,3) with zinc iodide, zinc bromide or mixtures thereof at a temperature of from about 150.degree. C to about 550.degree. C.

Abstract: Method for the conversion of butadiene (1,3) comprising contacting butadiene (1,3) with zinc iodide, zinc bromide (or mixtures thereof) and a reactant selected from methanol, dimethyl ether, or mixtures thereof, at a temperature of from about 180.degree. C to about 450.degree. C.

Abstract: Method for the production of triptane comprising contacting a reactant selected from methanol, dimethyl ether, or mixtures thereof, with zinc iodide at a temperature of from about 180.degree. to about 240.degree. C.

Abstract: Method for the production of triptane comprising contacting a reactant selected from methanol, dimethyl ether, or mixtures thereof, with zinc bromide at a temperature of from about 210.degree. to about 245.degree. C.

Abstract: The reaction of hydrogen and carbon oxides (carbon monoxide and carbon dioxide) to form methane at temperatures above 500.degree. C is promoted by carrying out the reaction in the presence of a molten metal salt-based catalyst system comprising a molten metal salt carrier selected from the class consisting of the halides and carbonates of alkali metals and alkaline earth metals and the halides of zinc, copper, manganese, cadmium, tin and iron, and mixtures thereof, melting below 1000.degree. C; said molten salt having dispersed therein one or more catalytically active metals selected from the class consisting of iron, molybdenum, manganese, nickel, cobalt, zinc, titanium, silver, copper and thorium in the form of finely divided elemental metals, metal oxides and/or metal carbides.

Abstract: A sulfur resistant methanation catalyst and the process to recover the same are disclosed. The catalyst comprises a molten metal salt carrier selected from the class consisting of the halides of zinc and cadmium, and mixtures thereof, melting below 1000.degree. C, said molten salt having dispersed therein one or more catalytically active metals selected from the group consisting of iron, molybdenum, manganese, nickel, cobalt, zinc, titanium, silver, copper and thorium. The recovery process comprises separating the metal sulfide, contacting the sulfide with a hydrogen halide at a reduced temperature, and recycling the resultant molten metal salt halide to the methanation reactor.
