Abstract: A method of purifying alcohol produced in a process that includes the Oxo process is disclosed. Aldehyde from the Oxo process that remains with the alcohol is removed by a reaction with an alkali sulphite to produce an insoluble adduct and alcohol having a reduced amount of aldehyde mixed with it. The adduct is removed from the alcohol by filtration.

Abstract: A catalyst for non-oxidative dehydrogenation of alkanes and a method for making and using the same is disclosed. The catalyst can include vanadium oxide derived from vanadyl oxalate. More particularly the catalyst is prepared by a method comprising the steps of: (a) contacting a transition alumina support with an aqueous solution comprising a vanadium carboxylate material solubilized therein; (b) heating the contacted alumina support to remove the water and produce a catalyst precursor material in solid form; and (c) heating the solid catalyst precursor material in the presence of an oxidizing source at a temperature of 500 to 800° C. to produce an alumina supported catalytic material comprising vanadium oxide. The catalyst can be further modified with an alkali metal oxide like potassium oxide, the precursor thereof being introduced with the impregnation solution.

Abstract: A method of storing and/or transporting oxo alcohol, comprises: combining an oxo alcohol having an initial aldehyde content X and an initial peroxide content Y with 5 ppm to 100 ppm of a phenolic antioxidant, preferably a phenolic antioxidant without ester linkage groups; and storing and/or transporting the oxo alcohol. The oxo alcohol can be used to produce a plasticizer, e.g., without adversely affecting color.

Abstract: Disclosed are shaped dehydrogenation catalysts, methods for making the catalysts, and methods for dehydrogenating a hydrocarbon using the catalyst. A method for making the shaped dehydrogenation catalyst can include combining a group 13 metal precursor and a group 1 metal precursor with a catalyst support precursor to form a shapeable material, shaping the shapeable material to form a wet shaped material, drying the wet shaped material to form a dry shaped material, and calcining the dry shaped material to form the shaped dehydrogenation catalyst.
