Implementations of the disclosed subject matter provide a process for producing ethylene glycol and propylene glycol from a sorbitol feed which may include contacting the sorbitol feed with hydrogen in a reactor in the presence of a solvent and a bi-functional catalyst system. The bi-functional catalyst system may include a first catalyst comprising a copper compound, a zinc compound, and an additional metal compound and a second catalyst comprising sodium carbonate.

A method of preparing a supported gas separation membrane, comprising: preparing crystalline seeds from a synthesis mixture comprising an aluminum source, a phosphorous source, a silicon source, at least one organic templating agent and water; applying the seeds to a porous support to produce a seeded porous support; contacting the seeded porous support with a synthesis gel under hydrothermal synthesis conditions to produce a coated porous support; and calcining the coated porous support is described. A supported gas separation membrane made by this method is also described.

Method of making a gas separation molecular sieve membrane

A method of making a supported gas separation molecular sieve membrane. In this method a porous support, which is preferably pretreated, is contacted with a molecular sieve synthesis mixture under hydrothermal synthesis conditions. The contacting step is conducted for a shortened crystallization time period. The resulting coated porous support is calcined to yield the supported gas separation molecular sieve membrane having particularly good gas separation characteristics.

A process for making primary haloalkanes by catalytic distillation of internal haloalkanes which comprises a) introducing an internal haloalkane feed into a catalytic distillation column; b) isomerizing at least a portion of the internal haloalkane feed in the presence of an internal haloalkane isomerization catalyst at a temperature at or above the boiling point of the internal haloalkanes and below the temperature and pressure at which hydrogen halide is formed to form primary haloalkanes; and removing the primary haloalkanes from the catalytic distillation column.

There is provided a new branched primary alcohol composition and the sulfates thereof exhibiting good cold water detergency and biodegradability. The branched primary alcohol composition has an average number of branches per chain of at least 0.7, having at least 8 carbon atoms and containing both methyl and ethyl branches. The primary alcohol composition may also contain less than 0.5 atom % of quaternary carbon atoms, and a significant number ethyl branches, terminal isopropyl branches, and branching at the Cposition relative to the hydroxyl carbon. The process for its manufacture is by skeletally isomerizing an olefin feed having at least 7 carbon atoms followed by conversion to an alcohol, as by way of hydroformylation, and ultimately, sulfation to obtain a detergent surfactant. Useful catalysts include the zeolites having at least one channel with a crystallographic free diameter along the x and/or y planes of the [001] view ranging from greater than 4.2 &#x212b; and less than 7 &#x212b;, but allows one to skeletally isomerize the olefin to produce a variety of branches, while retaining ready biodegradability and good cold water detergency.

This invention provides for a process to convert branched or linear alkanes to branched or linear alpha olefins (AO) of the same carbon number. The process comprises the steps of: a) halogenating linear alkanes, branched alkanes, or a mixture of linear and branched alkane to produce a mixture containing primary mono-haloalkanes and hydrogen halide; b) separating the hydrogen halide from the mixture and optionally neutralizing it with a metal oxide to produce a partially halogenated metal oxide and/or metal halide which may be regenerated; c) separating the primary mono-haloalkanes from the mixture; d) reacting the separated primary mono-haloalkanes with a metal oxide to produce a mixture of products that contains alpha olefins, unconverted primary mono-haloalkanes, possibly other reaction products, and a partially halogenated metal oxide and/or metal halide which may be regenerated; e) regenerating the partially halogenated metal oxide and/or metal halide to halogen and/or acid and a metal oxide (such as Cl) for recycle by reaction with air or oxygen ; and f) removing the unreacted primary mono-haloalkane from the reaction mixture and then purifying the alpha olefin.
