Abstract: A process for the catalytic alkylation of an aromatic substrate with an alkylating agent is disclosed that comprises contacting the aromatic substrate and the alkylating agent in sequential alkylation zones to obtain an alkylaromatic. The first catalyst comprises UZM-8 zeolite and the second catalyst comprises beta zeolite. The process is particularly well suited for the alkylation of benzene with propylene to produce cumene.

Abstract: The present invention provides a catalyst particle of an inner core, an outer layer surrounding and bonded to the inner core, the outer layer of a zeolite beta catalyst, and the outer layer having a volumetric fraction from about 0.17 to about 0.62 of the entire catalyst particle.

Abstract: The present invention provides a process for decomposing a cumene hydroperoxide to produce phenol and acetone. The process utilizes a solid catalyst that can be non-layered or layered. The process includes: (1) introducing a process stream containing cumene hydroperoxide into a reaction vessel; (2) contacting the process stream with catalyst particles to form a process stream; and (3) withdrawing a portion of the product stream from the reactor and recovering phenol and acetone products.

Abstract: A process for converting polyalkylaromatics to monoalkylaromatics, particulary cumene, in the presence of a modified Y-85 zeolite is disclosed. The process attains greater selectivity, reduced formation of undesired byproducts, and increased activity.

Abstract: Catalysts for converting polyalkylaiomatics to monoalkylaromatics, particularly cumene and ethyl benzene are disclosed which comprise modified Y-85 or LZ-210 zeolites. For cumene and ethylbenzene production, a disclosed catalyst, made of 80 wt % zeolite and 20 wt % alumina binder on a volatile-flee basis, has one or more of the following physical characteristics: (1) an absolute intensity of the modified Y zeolite as measured by X-ray diffraction (XRD) of preferably at least 50 and (2) a framework aluminum of the modified Y zeolite of preferably at least 50% of the aluminum of the modified Y zeolite.

Abstract: A process for the alkylation of aromatics with olefins using a solid catalyst bed containing UZM-8 zeolite is disclosed. A polyalkylated aromatic is passed to the catalyst bed to reduce the concentration of the olefin at alkylation conditions. A portion of the effluent recovered from the catalyst bed may be recycled to the catalyst bed. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. The process disclosed herein is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.

Abstract: The invention provides a fertile transgenic monocot, e.g., maize, plant encoding an endosperm specific prolamin box binding factor peptide (PBF) that is expressed so as to increase the methionine and/or lysine content of the seeds of said plant over said content in the seeds of the corresponding plant that lacks said gene, wherein said corresponding plant was used to prepare said transgenic plant, or an ancestor of said transgenic plant.

Abstract: A process for the decomposition of a cumene oxidation product mixture to produce phenol and acetone with reduced by-product formation by introducing the cumene oxidation mixture into an inlet of a decomposing vessel containing indirect heat exchange surfaces wherein the cumene oxidation product mixture and a circulating stream are admixed, reacted and cooled by passage around the indirect heat exchange surfaces.

Abstract: A process for decomposing a cumene oxidation product mixture containing cumene hydroperoxide (CHP) and dimethylphenolcarbinol (DMPC) to produce phenol and acetone.

Abstract: Disclosed is a process and apparatus for removing nitrogen compounds from an alkylation substrate such as benzene. A conventional adsorbent bed can be used to adsorb basic organic nitrogen compounds and a hot adsorbent bed of acidic molecular sieve can adsorb the weakly basic nitrogen compounds such as nitrites. Water facilitates the adsorption of the weakly basic nitrogen compounds. Running an alkylation substrate stream from a fractionation column of elevated temperature and suitable water concentration to the hot adsorbent bed may be advantageous.

Abstract: The present invention provides compounds of formula I and pharmaceutically acceptable salts thereof. The formula I compounds induce mitotic arrest thereby making them useful as anti-cancer agents. The formula I compounds are also useful for the treatment of other diseases which can be treated by inducing mitotic arrest.

Abstract: An integrated generator, compressor and welding power supply sized to fit within a pickup bed. The lower portion of the housing is sized to fit between the wheel wells of a pickup truck bed, while an upper housing portion is sized to extend over at least one bed wall. The position of the upper housing portions may be changed either vertically or horizontally to accommodate different makes or models of trucks. The lower housing portion includes feet extending downwardly therefrom, to suspend a bottom side of the lower housing above the floor of the truck bed, and thereby permit access to the bed floor beneath the unit. The lower portion contains an internal combustion engine for generating mechanical power, an alternator, and electrically driven compressors. Ducting and baffles facilitate air flow and cooling in this portion. A fuel tank and a control panel are positioned in the upper housing portions.

Abstract: The invention relates to transgenic plants that demonstrate enhanced expression of a plant transcription factor under the control of a seed specific promoter such that expression of the transcription factor activates transcription of a native or non-native coding sequence in the plant. The invention further relates to a method of generating such transgenic plants and methods for enhancing the level of expression of a selected heterologous protein in seeds of such transgenic plants.
