1,3-propanediol is prepared in a process which involves hydroformylating ethylene oxide:

Cobalt-catalyzed process for preparing 1,3-propanidiol

The invention described herein provides a process for recycling a mixed polymer recycle stream containing polyester polymers, particularly polyethylene terephthalate (PET) typically in the form of carbonated soft drink or other containers. This novel process includes the steps of: (1) contacting the mixed polymer recycle stream with a solvent which selectively dissolves the PET. (2) separating the selective solvent containing PET from the residual mixed polymer, (3) cooling the selective solvent to precipitate the PET, and (4) removing the selective solvent from the precipitated PET. It is preferable that the mixed polymer recycle stream be prepared for recycling by conventional steps, such as water washing. In a preferred embodiment, the mixed polymer recycle stream is chemically washed subsequent to water washing and prior to contact with the selective solvent. The PET recovered is preferably combined with 'virgin' PET and further processed to increase its molecular weight.

This invention relates to a process for the two-stage hydrogenation of methyl esters which comprises: a) contacting and reacting one or more detergent range methyl esters with hydrogen under predominantly liquid phase hydrogenation conditions at a temperature of less than about 230.degree. C., in the presence of a catalyst comprising a copper compound, a zinc compound, and at least one compound selected from the group consisting of aluminum, zirconium, magnesium, a rare earth and mixtures thereof, to produce an alcohol product and a wax ester product, and b) contacting and reacting the wax ester product from step a) with hydrogen under predominantly liquid phase hydrogenation conditions at a temperature greater than about 220.degree. C. in the presence of a catalyst comprising a copper compound, a zinc compound, and at least one compound selected from the group consisting of aluminum, zirconium, magnesium, a rare earth and mixtures thereof, to produce an alcohol product.

This present invention relates to a disproportionation catalyst and to a process for preparing a disproportionation catalyst comprising forming a calcined composite comprising at least one of molybdenum and rhenium supported on an inorganic oxide support and contacting the calcined composite with an organoborane compound. The invention further relates to a process for the disproportionation of olefinic hydrocarbons comprising contacting at least one olefinic hydrocarbon with a catalyst comprising at least one of molybdenum and rhenium supported on an inorganic oxide support promoted with an organoborane compound. More specifically, the invention relates to the uses of an organoborane compound promoted molybdenum and rhenium supported on an inorganic oxide support for the production of linear alpha olefins from a mixture of internal olefins and ethylene. The invention also relates to the application of the described promoted catalyst for the production of 1,6-heptadiene and 1,6-octadiene from the reaction of cyclopentene with ethylene and propylene, respectively, and the fact that the presence of organoborane in the catalyst allows the reaction to be carried out at very mild temperature while obtaining high product selectivity.

A process for the removal of H.sub.2 S from sour gaseous streams is disclosed in which the sour gaseous stream is contacted with a solution containing solubilized iron chelates of a specified organic acid or acids. The contacting is carried out in first and second contacting zones, the first being a gas-solution mixture formation zone and the second comprising a plurality of contacting sections adapted to provide reaction of the H.sub.2 S in the sour gaseous stream with the iron in the contacting solution without plugging due to deposition of sulfur.

A feedstock containing alpha olefins and internal olefins is converted into a first product having an enhanced internal olefin content over that of the feedstock and into a second product having an enhanced alpha olefin content over that of the feedstock by:

Process for separating alpha and internal olefins

This invention relates to a process for producing an olefin product having an enhanced alpha olefin content from an olefin feedstock containing internal olefins or a mixture of internal and alpha olefins which includes:

Process for converting internal olefins to alpha olefins

Excess water is removed from regenerated redox solution by contacting a downwardly flowing spray of regenerated redox solution with a stream of inert gas at a rate and pressure sufficient to provide for the substantial saturation of the gas with excess water impurities in the redox solution without the substantial undesirable oxidation of the metal in the regenerated redox solution.

Water removal in a redox process

Froth or foam sulfur particle accumulation during the recovery of sulfur particles from a zone containing regenerated redox solution is reduced by agitating and removing the sulfur slurry in a plurality of streams, including at least one stream at a short distance from the top of the solution in the zone and at least one stream from the bottom of the zone and optionally recombining the streams after removal.

A process for the removal of H.sub.2 S from sour gaseous streams is disclosed in which the sour gaseous stream is contacted with a solution containing solubilized iron chelates of nitrilotriacetic acid. The contacting is carried out in first and second contacting zones, the first being a gas-solution mixture formation zone and the second comprising a plurality of contacting sections adapted to provide reaction of the H.sub.2 S in the sour gaseous stream with the iron in the contacting solution without plugging due to deposition of sulfur.
