Abstract: The invention relates to a process for the separation of various dialkyl multinuclear aromatic compounds from a feed stream of mixed isomers of those compounds. A shape selective adsorbent is employed resulting in a process that is more efficient than processes based upon prior separation techniques. Of special interest are combination processes involving synthesis steps followed by sorption steps using the same shape selective materials.

Abstract: Tischtschenko condensation of aldehydes is used to remove aldehydes from dry ketone-containing streams. The Tischtschenko condensation is used to condense the aldehydes into esters whose boiling points are significantly different than the ketones, greatly simplifying the separation of the esters from the ketones. An organic extraction step is used to obtain a substantially dry ketone containing stream. One particularly preferred class of extraction solvents is selected from the group consisting of butane, pentane, hexane, heptane, octane, nonane, decane and mixtures thereof. In particularly preferred embodiments, the Tischtschenko reaction is used in the context of aqueous-phase catalyzed olefin oxidation to ketones. The aldehyde to ester condensation permits easy and efficient removal of the aldehyde analogs of the desired ketones.

Abstract: This invention is directed to a catalyst system for use in the alkylation of isoparaffin with olefins. More specifically, this invention is directed to an improved catalyst system containing specified amounts of water and a component of that system comprising certain transition aluminas promoted with a Lewis acid (preferably BF3). In addition, this invention is a catalytic process for the alkylation of isoparaffin with olefins. The catalyst component is produced by contacting the transition alumina with the Lewis acid at relatively low temperatures. The catalyst system comprises that component and an additional amount of free Lewis acid. The process entails isoparaffin alkylation with olefins using the catalyst component and its allied catalyst system.

Abstract: This invention is a combination process for removal of sulfur oxides (SOx) from gases containing both the SOx and oxygen (106). The fluid used to remove the SOx contains sulfuric acid and bromine. The SOx is converted to sulfuric acid and the bromine is thereafter converted to hydrobromic acid. The hydrobromic acid is concentrated and catalytically converted to bromine for ultimate recycling to the SOx removal step (132). The SOx is finally recovered as a strong sulfuric acid (104).

Abstract: This invention is a noncatalyzed process for the production of carbonyls, particularly beta -hydroxy aldehydes, by the aldol condensation of, for example, acetophenone and formaldehyde. In this process, neither base nor acid is added to the reaction mixture. Operation of a specific variation of the process results in a high yield of 3-hydroxy-1-phenyl-1-propanone and, because of the absence of added catalysts and of the choice of reaction conditions, does not produce significant amounts of dehydration products such as 1-phenyl-2-propene-1-one or of overcondensation products.

Abstract: This invention is a catalyst and a process using that catalyst for oxidizing hydrogen bromide to form elemental bromide. The inventive catalyst comprises a composition of promoted or stabilized copper bromide on a zirconium-containing support. In the figure, an HBr stream (202) is sent to an evaporator (204) and to a super heater (206). The O2 feed stream (208) is warmed with heater (210). The O2 and HBr mixed reactor feed stream (214) is introduced into reactor (216). The reactor stream (218) may be cooled in two stages (220) and (222) and also condensed. The device (230) separates condensed liquid into (224), (226) and (228) streams. The vapor stream (228) is chilled in refrigeration unit (232) to remove Br2. A resulting Br2 stream (234) is mixed with stream (224). A non-condensed O2 vapor stream (236) is scrubbed in a gas treater (238). The treated O2 is vented (240) or may be recycled to reactor (216). The aqueous stream (226) coming from the separator (230) is then stripped of Br2 in a distillation column (242) and produces two streams (244) and (250), where (240) is condensed in condenser (246) and collected in drum (248). The stream (250) is mixed with other Br2 streams (224) and (234) for further treatment in counter-current absorption tower (256) producing a Br2 product stream (258).
