Ultra high‐performance liquid chromatography of porphyrins in clinical materials: column and mobile phase selection and optimisation
Authors: Benton Christopher M. , Lim Chang Kee , Moniz Caje , Jones Donald JL 
Published: October 2011

ABSTRACTUltra high‐performance liquid chromatographic (UHPLC) systems on columns packed with materials ranging from 1.9 to 2.7 µm average particle size were assessed for the fast and sensitive analysis of porphyrins in clinical materials. The fastest separation was achieved on an Agilent Poroshell C18 column (2.7 µm particle size, 50 × 4.6 mm i.d.), followed by a Thermo Hypersil Gold C18 column (1.9 µm particle size, 50 × 2.1 mm i.d.) and the Thermo Hypersil BDS C18 column (2.4 µm particle size, 100 × 2.1 mm i.d.). All columns required a mobile phase containing 1 m ammonium acetate buffer, pH 5.16, with a mixture of acetonitrile and methanol as the organic modifiers for optimum resolution of the type I and III isomers, particularly for uroporphyrin I and III isomers. All UHPLC columns were suitable and superior to conventional HPLC columns packed with 5 µm average particle size materials for clinical sample analysis. Copyright © 2011 John Wiley & Sons, Ltd.
Effects of Contaminants on the Mass‐Transfer Characteristics of a Two‐Impinging‐Streams Gas‐Liquid Reactor
Authors: Dehkordi A. M. , Savari C. 
Published: October 2011

AbstractThe mass‐transfer characteristics of a new type of two‐impinging‐streams reactor (TISR) was studied by means of sodium sulfite solution as the liquid phase and air as the gas phase, in the presence and absence of various types of surface‐active agents (SAAs). The influences of anionic, cationic, and nonionic SAAs on the specific interfacial area and overall volumetric mass‐transfer coefficient obtained in the TISR were investigated. It was found that the presence of a little amount of the above‐mentioned contaminants increases the specific interfacial area and decreases the overall volumetric mass‐transfer coefficient. On the basis of the experimental results obtained for various types of SAAs, correlations were derived for the interfacial area as well as the Sherwood number for the liquid phase in terms of Froude, Reynolds, Schmidt, and Morton numbers.
Identification of Flow Regimes in a Concurrent Gas Liquid Upflow through Packed Beds
Authors: Raghavendra Rao A. V. , Kishore Kumar R. , Sankarshana T. , Khan A. 
Published: October 2011

AbstractThe flow regimes bubble flow, pulse flow, and spray flow were identified by visual observation in a packed column. Three gas‐liquid systems (air/water, air/56 % glycerol, and air/monoethanolamine) and four column packings (Raschig rings, Intalox saddles, and two sizes of spheres) were investigated to cover wide ranges of physical properties of gas liquid systems and characteristics of column packings affecting the flow regime transition. Criteria for the flow regime transition were developed in terms of system and operating variables.
CFD Simulations for Safety of Chemical Reactors and Storage Tanks
Authors: Rudniak L. , Milewska A. , Molga E. 
Published: October 2011

AbstractTwo CFD models were formulated for the stirred tank reactor and the storage tank, respectively. With use of the elaborated models, for various thermal runaway scenarios, spatial distributions of liquid velocity, temperature, and key reactant concentration were determined as a function of time. Knowledge of temperature nonuniformity inside the reactor and storage tank vessels is particularly crucial for the appropriate location of temperature sensors, which assures a detection of thermal runaway as early as possible. The results obtained indicate that the CFD models can be very useful to elaborate efficient and robust methods for online early warning of runaway.
Mechanistic Analysis of Iridium(III) Catalyzed Direct CH Arylations: A DFT Study
Authors: García‐Melchor Max , Gorelsky Serge I. , Woo Tom K. 
Published: October 2011

AbstractIn a recent experimental work the Ir complex [Ir(cod)(py)(PCy3)](PF6) (that is, Crabtree’s catalyst) has been shown to catalyze the CH arylation of electron‐rich heteroarenes with iodoarenes using Ag2CO3 as base. For this process, an electrophilic metalation mechanism, (SEAr) has been proposed as operative mechanism rather than the concerted metalation–deprotonation (CMD) mechanism, widely implicated in Pd‐catalyzed arylation reactions. Herein we have investigated the CH activation step for several (hetero)arenes catalyzed by a IrIII catalyst and compared the data obtained with the results for the PdII‐catalyzed CH bond activation. The calculations demonstrate that, similar to PdII‐catalyzed reactions, the IrIII‐catalyzed direct CH arylation occurs through the CMD pathway which accounts for the experimentally observed regioselectivity. The transition states for IrIII‐catalyzed direct CH arylation feature stronger metal–C(arene) interactions than those for PdII‐catalyzed CH arylation. The calculations also demonstrate that ligands with low trans effect may decrease the activation barrier of the CH bond cleavage.
Bicontinuous Cubic Mesoporous Materials with Biphasic Structures
Authors: Garcia‐Bennett Alfonso E. , Xiao Changhong , Zhou Chunfang , Castle Toen , Miyasaka Keiichi , Terasaki Osamu 
Published: October 2011

AbstractThe replication of amphiphilic systems within an inorganic silica matrix allows the study of the fundamental properties of mesostructural changes, that is, kinetic and structural parameters. Herein we report a detailed study of the transition between cubic bicontinuous mesostructure with space groups Ia$\bar 3$d and Pn$\bar 3$m symmetry, which are associated with the minimal G and D surfaces, respectively. The transition may be induced through micellar swelling of the anionic amphiphilic surfactant N‐lauroyl alanine by trimethylbenzene. Rich kinetic behaviour is observed and has been exploited to prepare particles with biphasic structures. Transmission electron microscopy evidence indicates that there is epitaxial growth from one mesostructure to the other involving the [111] and [110] orientations of the Ia$\bar 3$d and Pn$\bar 3$m symmetry structures, respectively. From kinetic studies, we show that the formation of the Ia$\bar 3$d mesophase is preceded by a hexagonal phase (plane group p6mm) and an epitaxial relationship has been observed involving the sixfold or $\bar 3$ axis orientations of both structures. Our data suggests that the Pn$\bar 3$m mesostructure is kinetically stable at low temperatures whereas the Ia$\bar 3$d mesostructure is the more stable structure after prolonged periods of hydrothermal treatment. We present evidence from transmission electron microscopy and small‐angle X‐ray diffractograms and also electron crystallography modelling of the unit cells at particular points in the structural change.
