The oxidation process for the manufacture of higher aryl esters comprising contacting the reaction mixture of a higher aromatic hydrocarbon, an organic solvent, a carboxylic acid and molecular oxygen in the liquid phase at an elevated temperature with a catalyst composed of palladium or a compound of palladium, an antimony compound and a compound of at least one member selected from the group consisting of alkali metals and alkaline earth metals is described.

A higher alcohol synthesis catalyst precursor comprises a homogeneous, highly crystalline, hydroxycarbonate compound containing copper, zinc and at least one element selected from the group consisting of aluminium, manganese and chromium. It also comprises at least one element from at least one of the followng groups of the Periodic Table of Elements: Group IIIA, Group IIIB, Group IVB and Group VIIB.

An improved process for the preparation of higher unsaturated ketones, such as geranylacetone and farnesylacetone, by reacting a .beta.,.gamma.-unsaturated alcohol and an alkyl acetoacetate at an elevated temperature in the presence of an organic aluminum compound, with elimination, and removal, of the alcohol derived from the alkyl acetoacetate in a reactor system carrying a fractionating column. The improvement in the purity, yield, and especially space-time yield of the product is achieved by...

In a rhodium-catalyzed hydroformylation process employing olefin reactants having from 3 to 20 carbon atoms to produce products rich in normal aldehydes, the efficiency of the catalyst in producing such products is substantially uneffected and propionaldehyde is also produced by employing ethylene as a coreactant along with the olefin.

A process for the preparation of a straight-chain or branched alkene which has 20 to 24 carbon atoms and in which the ethylenic bond is located after a carbon atom numbered between 8 and 11, which process comprises reacting, in an anhydrous solvent, preferably in an oxahydrocarbon an organometallic copper compound with an alkyl or alkenylsulfonate.

A carbon-bearing feedstock is reacted with oxygen and water in a partial oxidation reactor to produce a mixture of hydrogen and carbon monoxide. The hydrogen is removed as a first product and the remaining carbon monoxide is reacted with steam over a bifunctional catalyst to produce higher hydrocarbons and carbon dioxide. The bifunctional catalyst provides water gas shift and Fischer-Tropsch functions.

This invention relates to a process for separating an aldehyde that contains at least seven carbon atoms and that is free of alpha substituents from a solution containing the aldehyde and a non-polar organic liquid which process comprises contacting the solution with water under conditions such that a solid hydrate of the aldehyde forms and separating the solid hydrate from the solution. This invention also relates to novel hydrates so produced.

A method of making a higher olefin product from a C.sub.4.sup.+ fraction separated from the hydrocarbon product produced by an oxygenate to olefin reaction unit. The C.sub.4.sup.+ fraction primarily contains butenes which may be directed to a higher olefin reaction unit without removing isobutenes, butanes, and/or butadiene. The C.sub.4.sup.+ fraction is particularly well suited for the production of higher olefins because of its high olefin content, low branching number, and low contaminent lev...

Higher diamondoid derivatives capable of taking part in polymerization reactions are disclosed as well as intermediates to these derivatives, polymers formed from these derivatives and methods for preparing the polymers.

The higher chloromethanes, i.e., CH.sub.2 Cl.sub.2, CHCl.sub.3 and CCl.sub.4, are simultaneously produced by chlorinating methyl chloride with chlorine in a first reaction zone A, chlorinating at least one of the higher chloromethanes CH.sub.2 Cl.sub.2 and CHCl.sub.3 with chlorine in a parallel second reaction zone B, combining the reaction products from said first and said second reaction zones A and B, separating higher chloromethanes from said combined reaction products, and recycling at leas...
