Abstract: A process for producing an alkylaromatic compound comprises providing a first feed comprising an alkylatable aromatic compound and a second feed comprising an alkylating agent, wherein at least the first feed contains an impurity compound comprising at least one of nitrogen, halogens, oxygen, sulfur, arsenic, selenium, tellurium, phosphorus, and Group 1 through Group 12 metals The first feed is passed through an adsorbent comprising a metal-organic framework material under conditions effective to reduce the amount of impurity compound in the first feed and produce a purified first feed. The purified first feed and at least part of the second feed are then contacted with an alkylation catalyst composition under alkylation conditions effective to convert at least part of the alkylatable aromatic compound in the purified first feed to the desired alkylaromatic compound and produce an alkylation effluent.

Abstract: An in vitro release test (IVRT) method and system is provided for drug release testing. The IVRT method, referred to herein as adaptive perfusion, employ tangential-flow filtration (TFF), where released drug products that are smaller than a molecular weight cutoff (MWCO) of a membrane filter pass therethrough into the permeate. Unreleased drug products are retained by the pores of the filter and are recirculated to a retentate reservoir. Fresh media is provided to the retentate in order to maintain a constant total volume for the sample as well as to maintain sink conditions for the drug release. Drug concentration in the retentate and permeate are evaluated by in situ monitoring with one or more sensors and/or by periodic removal of aliquots from the respective reservoirs. In some embodiments, the membrane filter can be conditioned prior to use in order to improve the accuracy, precision, or both of the subsequent testing.

Abstract: Methods for identifying hydrocarbon contamination sources may include fingerprinting hydrocarbons using isotopocule analyses for BTEX compounds. For example, methods for identifying hydrocarbon contamination sources may comprise: extracting BTEX compounds from a sample; measuring the isotopocule composition of the BTEX compounds; and determining a characteristic of the sample based on the isotopocule composition. Such characteristics may include, but are not limited to, the characteristic of the sample comprises one or more selected from the group consisting of: a source of the sample, a condition at which the sample formed or was last equilibrated, a migration time from a source to a sample location, weathering of the sample, and degree to which the sample is anthropogenic and naturally-occurring.

Abstract: This disclosure provides polyamine sorbent compositions for the separation of metals from aqueous solutions. The polyamine sorbent compositions comprise a silica support, an aminosilane bound to the silica support, an epoxysilane bound to the silica support, and a polyamine where the polyamine is chemically tethered onto a solid silica support through via the epoxysilane. The polyamine may be further stabilized within the bulk sorbent through hydrogen bonding interactions with the aminosilane. The sorbent compositions resist leaching by H2O in an aqueous stream containing heavy oxyanion-based (and other) metals and demonstrate stability over a pH range of 2-14. The sorbent compositions are useful for the separation of metals from aqueous solutions. The cationic heavy metals are captured by the co-existing amine groups (—NH2, —NH, —N) from the polymeric network while additional metal capture capacity is derived from the introduction of a secondary silane linker.

Abstract: A two-step chromatography purification scheme is described which selectively captures and isolates the genome-containing rAAV vector particles from the clarified, concentrated supernatant of a rAAV production cell culture. The process utilizes an affinity capture method performed at a high salt concentration followed by an anion exchange resin method performed at high pH to provide rAAV vector particles which are substantially free of rAAV intermediates.
