Abstract:
Improved procedure for the production of hydrogen peroxide by oxidation with molecular oxygen of secondary alcohols admixed with primary alcohols and/or ethers.
Abstract:
Hydrogen peroxide is produced by a process which uses solid, insoluble, supported anthraquinone as catalyst. The supported anthraquinone is converted to supported anthrahydroquinone utilizing soluble reducing agentsor by hydrogenation with a hydrogen-donating organic substrate such as an alcohol, followed by reaction with oxygen, to regenerate anthraquinone and to form hydrogen peroxide, which can be solvent extracted from the solid catalyst.
Abstract:
A process is provided whereby the hydrogen peroxide-containing oxidate from methyl benzyl alcohol oxidation is contacted with ethyl benzene extractive solvent and a hydrogen peroxide phase is separated from a solvent phase which also contains methyl benzyl alcohol and acetophenone.
Abstract:
Supported catalysts include a solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. Active catalyst particles are supported on the functionalized support material. The acid functionalized support material is made by reacting a solid support with an inorganic acid containing agent such as sulfuric acid or para-toluene sulfonic acid. An organic anchoring agent is used to form and anchor catalyst nanoparticles to the acid functionalized support material. The supported catalyst can be sized and shaped for use in any type of reactor, including a fixed bed or fluidized bed reactor. The methods of the present invention also include a process for the direct synthesis of hydrogen peroxide using the supported catalyst.
Abstract:
Hydrogen peroxide is produced by a process which uses solid, insoluble, supported anthraquinone as catalyst. The catalyst is reduced to supported anthrahydroquinone using a hydrogen-donating organic substrate such as an alcohol, followed by reaction with oxygen, suitably photochemical reaction, to regenerate anthraquinone and to form hydrogen peroxide, which can be solvent extracted from the solid catalyst.
Abstract:
Hydrogen peroxide is produced by liquid phase molecular oxygen oxidation of methyl benzyl alcohol, the reaction being carried out such that the oxygen absorption rate is 90% or more of the maximum at the reaction conditions and the exit gas oxygen partial pressure is not greater than 3.0, the minimum necessary to establish the maximum oxygen absorption rate.
Abstract:
Process comprising contacting and reacting a diarylmethanol having 13 to 25 carbon atoms and of the formula RCHOHR' wherein each of R and R' is aryl, the same or different, in the liquid state, at a temperature of about 130.degree.-260.degree. C., with gaseous oxygen to produce hydrogen peroxide and diaryl ketone of the formula RCOR' wherein R and R' are the same as above.
