A method for producing catalyst by impregnating a support with an aqueous solution of CuO, drying the impregnated support at about 90.degree. C. to about 150.degree. C. to provide a powdery product support impregnated with about 0.1 to about 5 weight percent CuO. A method for preparing aldehydes from olefins in the presence of an oxygen containing gas and a catalyst as prepared above.

Olefin oxidation with supported CuO catalyst

An olefinically unsaturated compound containing from 3 up to about 18 carbon atoms per molecule and having the formula ##STR1## wherein each R.sub.1, R.sub.2, R.sub.3 and R.sub.4 is independently selected from a group consisting of hydrogen, alkyl, and cycloalkyl radicals and wherein there is at least one hydrogen attached to a carbon atom adjacent to the olefinic group is oxidized in a liquid reaction medium containing methyl formate. In a preferred embodiment of the invention propylene is oxidized in the presence of methyl formate solvent.

A method for preparing aldehyde from aliphatic olefin in the presence of oxygen and a catalyst containing Sn, P, Li, and O.

Aliphatic olefin oxidation using catalyst containing Sn, P, O, Li

Polymers are prepared using dienyllithium initiators, a reaction product of organolithium with a 1,4-diolefin, to polymerize olefinically unsaturated monomers such as conjugated dienes under solution polymerization conditions to provide unsaturated polymers, branched polymers, graft polymers, polymers prepared by sequential polymerization, and coupled polymers.

Dienyllithium initiated polymers

A supported silver-containing catalyst suitable for the oxidation of ethylene to ethylene oxide is prepared directly from silver nitrate. The oxidation of ethylene using that catalyst is also disclosed.

Catalyst and process for producing ethylene oxide

Bis(1,3-dienyl)dialkyltin, lead, and germanium compounds employed in the aqueous emulsion polymerization of conjugated dienes, optionally with vinyl comonomers, provide polymers with sufficiently high Mooney viscosity values as to be readily handled in plant operations, yet which exhibit controlled breakdown under milling to lower Mooney values suitable, for a variety of uses.

Cleavable branching agents in emulsion polymerization systems

Grignard reagents of halo-substituted conjugated dienes are prepared by reaction of 1- or 2-halo-substituted conjugated diene with magnesium metal employing a metal halide/saturated aliphatic halide catalyst system. The Grignard reagent can be employed in the preparation of hydroxy-substituted conjugated dienes and hydroxy-substituted allenes. Adjustment of the molar ratio of the metal halide to the halo-substituted conjugated diene permits favoring of hydroxy-substituted conjugated dienes or hydroxy-substituted allenes in the diene products.

Preparation of grignard reagents of halodienes and preparation of dienols

Copolymers of 2,4-pentadien-1-ol with conjugated dienes, optionally with copolymerizable olefinically unsaturated monomers, are prepared by aqueous emulsion polymerization.

Emulsion polymerized copolymers of 2,4-pentadien-1-ol

Diisoprenyl ether added to an alkadiene/monovinyl arene emulsion polymerization mixture increases the Mooney viscosity of a polymer.

Crosslinking in emulsion polymerization

Di(2-methylene-but-3-en-1-yl) ether, methods to make this compound and the use of this compound as a crosslinking agent are disclosed.

Diisoprenyl ether

Bicyclic triolefins are converted to peroxides, alchols and ketones.
