Bewertung von Zustandsgleichungen für Erdgase
Authors: Jerinić D. , Friedel L. , Schmidt J.
Published: August 2009

Zehn Zustandsgleichungen zur Vorausberechnung von Zustandsgrößen (z. B. Kondensatgehalte, Realgasfaktoren) von Erdgasen wurden hinsichtlich ihrer Wiedergabegenauigkeiten bewertet. Hierzu sind die Gleichungen zuerst anhand von Reinstoffdaten typischer Erdgaskomponenten und binärer Gas/Flüssigkeits‐Phasengleichgewichte validiert worden. Die Gemischeigenschaften wurden unter Verwendung der quadratischen Mischungsregel und binärer Wechselwirkungsparameter bestimmt. Mit den kubischen Zustandsgleichungen und der PCSAFT Gleichung werden nahezu alle Zustandsgrößen am verlässlichsten wiedergegeben. Die mittlere logarithmische Streuung liegt im Fall des Dampfdruckes, der Taudichte sowie der Siededichte bei etwa 4 % und bei der Tau‐ und Siedelinie des Gas/Flüssigkeits‐Phasengleichgewichtes bei 3 % bzw. 9 %. Mit steigender Nichtidealität der binären Systeme wurde auch eine Verschlechterung der Wiedergabegenauigkeit der Zustandsgleichungen festgestellt. Die Gegenüberstellung gemessener und mit den Zustandsgleichungen vorausberechneter Erdgas‐Kondensatgehalte verdeutlicht, dass im nahekritischen Gebiet der Erdgase keine zutreffenden Ergebnisse erzielt werden. Die mittlere logarithmische Streuung der Peng‐Robinson‐Zustandsgleichung beträgt im Fall der Nachrechnung des Kondensatgehaltes 47 % und mit der PCSAFT‐Gleichung lediglich 116 %. Bei der Vorausberechnung von Realgasfaktoren eines russischen Erdgases wurde mit allen untersuchten Zustandsgleichungen eine qualitativ und quantitativ zutreffende Wiedergabegenauigkeit erzielt. Die GERG‐2004‐Referenzzustandsgleichung eignet sich dabei am besten zur Berechnung von Realgasfaktoren, wobei auch mit der Peng‐Robinson‐ sowie der PCSAFT‐Zustandsgleichung eine gute Wiedergabegenauigkeit erzielt werden konnte. Zur Berechnung der Kondensatgehalte und Realgasfaktoren von Erdgasen eignet sich am besten die Peng‐Robinson‐Zustandsgleichung, da mit der PCSAFT‐ oder der GERG‐2004‐Gleichung die Erdgaskondensation nur unzutreffend bzw. erst gar nicht berechnet werden kann. Die Zustandsgleichungen sollten jedoch zur Berechnung der Kondensation im Betriebsbereich von Ferngasleitungen noch verbessert werden.

Published: August 2009

Die Gasphasenoxidation von o‐Xylol zu Phthalsäureanhydrid (PSA) in einem Rohrbündelreaktor wurde mit Hilfe eines quasihomogenen, 2‐dimensionalen, polytropen Modells simuliert. Für verschiedene Betriebsbedingungen wurden die Temperatur‐ und Konzentrationsfelder in den Reaktionsrohren berechnet. Dazu wurde der Reaktionsmechanismus nach Anastasov mit dem entsprechenden kinetischen Modell zu Grunde gelegt. Ziel der durchgeführten Berechnungen war es, Möglichkeiten zur Beeinflussung der Temperaturprofile und in Folge dessen zur Verbesserung der Selektivität durch eine veränderte Prozessführung aufzuzeigen.

Published: August 2009

The title compound, [Et4N][(PPh3)2ClRuB12H12], was unexpectedly isolated from the reaction of RuCl2(PPh3)3 with closo‐B10H102− in ethanol as a red air‐stable solid, and characterized by IR and a single crystal X‐ray diffraction analysis. Its formation results from the reaction of RuCl2(PPh3)3 and B12H122−, which was present as a byproduct in the preparation of B10H102−. It may be formally regarded as either a ruthenium(II) complex of closo‐B12H122− via three B‐H‐Ru three‐center two‐electron bonds, or as a 13‐vertex pileo 2n‐electron (n is the number of vertices) ruthenaborane cluster with a capped closo polyhedral skelecton. This is the first anionic and structurally characterized metal complex having a {RuB12H12} moiety.

Authors: ZHANG Qianyu , QIU Chenchen , FU Yanbao , MA Xiaohua
Published: August 2009

The electrochemical properties and overcharge protection mechanism of xylene as a new polymerizable electrolyte additive for overcharge protection of lithium ion batteries were studied by cyclic voltammetry tests, charge‐ discharge performance and battery power capacity measurements. It was found that when the battery was overcharged, xylene could electrochemically polymerize at the overcharge potential of 4.3–4.7 V (vs. Li/Li+) to form a thin polymer film on the surface of the cathode, thus preventing voltage runaway. On the other hand, the use of xylene as an overcharge protection electrolyte additive did not influence the normal performance of lithium ion batteries.

Published: August 2009

In weak acid medium, eosin Y (EY) has a strong absorption band in the visible light region, and the maximum absorption wavelength (λmax) is at 517 nm. There is no light absorption for polyvinylpyrrolidone (PVP) in 250–700 nm. When EY was reacted with PVP to form a binding product, a fading reaction of EY appeared and the maximum fading wavelength was still located at 517 nm. At the same time, a smaller absorption peak was observed at 545 nm. The extent of the fading (ΔA) is directly proportional to the concentration of PVP in the range of 0.40–3.20 mg· L−1. The fading reaction has high sensitivity. The molar absorptivity (ε) is 6.4×106 L·mol−1·cm−1 and the detection limit for PVP is 0.12 mg·L−1. The influencing factors for the reaction have been studied, and the results show that the selectivity is good. Based on this fact, a new fading spectrophotometric method for the determination of PVP with EY has been developed, which is simple and rapid, and it can be applied to the quantitative determination of PVP in beer samples.

Published: August 2009

A bis‐reactive cationic fixing agent, ethylenebis[N‐(2,3‐epoxypropyl)‐N,N‐dimethylammonium chloride] has been used as an aftertreatment reagent to improve the wash fastness of direct dyes on cotton. The effects of different pH conditions and concentrations on the effectiveness of this cationic fixing agent have been investigated. The results showed that aftertreatment at pH 11 produced dyeings with higher colour strength and better wash fastness than that at pH 7. In addition, the cationic agent at a low concentration was found to be more effective under both neutral and alkaline conditions.

Published: August 2009

ω‐(Pyrrol‐1‐ylalkyl)dimethylchlorosilanes with different chain lengths were adsorbed on silicon oxide surface, subsequently, the polypyrrole film was deposited on this modified substrate. The chemical deposition of polypyrrole on the modified surface was investigated by SEM and AFM. The thickness of deposited polypyrrole films on different chain adhesion promoter modified substrates has no big difference except that of the short chain length. The electric properties were investigated by current‐potential characterization. The results show that the value of the electrical current does not monotonically depend on the length of the spacer of the adhesive monolayer. The electric property shows that the charge carrier mobility is 1.4×10−4 cm2·V−1·s−1.

Published: August 2009

Background

Limited information exists regarding the association between subjective well‐being (SWB) and systolic blood pressure (SBP) among hypertensive patients with coronary artery disease (CAD).

Hypothesis

We tested the hypothesis that there is an association between SBP and SWB.

Methods

We studied 22,576 hypertensive CAD patients ≥ 50 years old in the INternational VErapamil SR‐Trandolapril Study (INVEST), a randomized, blinded‐endpoint trial of antihypertensive therapy in stable CAD patients. At each study visit, patients rated their SWB in the previous 4 weeks as “excellent,” “good,” “fair,” or “poor” prior to SBP recordings. The outcome measure was SWB of “fair” or “poor.” A longitudinal analysis using generalized estimating equations was performed to assess the association between SBP and odds of reporting fair/poor SWB, controlling for baseline SWB of fair/poor and angina reported during the study.

Results

Patients with higher SBP had higher odds of reporting fair/poor SWB. Specifically, compared with patients with SBP of ≤ 120, patients with SBP 140–150 > 150 − ≤ 160 and > 160 had about 90% and 2.5 times greater odds of feeling fair/poor, respectively (adjusted odds ratio [OR]: 1.5990, 95% confidence interval [CI]: 1.81–2.00 and adjusted OR: 2.53, 95% CI: 2.41–2.66). Those who reported angina in the 4 wks prior to a protocol visit had 2.2 times greater odds of reporting fair/poor SWB (adjusted OR: 2.2, 95% CI: 2.13–2.27). Female gender, black race, history of smoking, diabetes, myocardial infarction, stroke, and cancer also increased the odds of reporting fair/poor SWB.

Conclusions

Among hypertensive CAD patients, higher on‐treatment SBP is associated with greater odds of fair/poor SWB during follow‐up. Copyright © 2009 Wiley Periodicals, Inc.
Molecular Fingerprint Recombination: Generating Hybrid Fingerprints for Similarity Searching from Different Fingerprint Types
Authors: Nisius Britta , Bajorath Jürgen
Published: August 2009

Molecular fingerprints have a long history in computational medicinal chemistry and continue to be popular tools for similarity searching. Over the years, a variety of fingerprint types have been introduced. We report an approach to identify preferred bit subsets in fingerprints of different design and “recombine” these bit segments into “hybrid fingerprints”. These compound class‐directed fingerprint representations are found to increase the similarity search performance of their parental fingerprints, which can be rationalized by the often complementary nature of distinct fingerprint features.
Predictors of malignancy in thyroid fine‐needle aspirates “cyst fluid only” cases
Authors: Jaragh Mohammad , Carydis V. Bessie , MacMillan Christina , Freeman Jeremy , Colgan Terence J.
Published: August 2009

BACKGROUND:

A recent consensus conference on thyroid fine‐needle aspiration (FNA) cytology concluded that specimens with abundant histiocytes and few or no follicular cells should be interpreted as “cyst fluid only,” under the category of “nondiagnostic.” The purpose of the current study was to identify any cytomorphologic characteristics in this type of specimen that are predictive of an underlying malignancy.

METHODS:

Thyroid FNA cases with a report of cyst fluid only and a follow‐up thyroidectomy specimen were identified during a 3‐year period. A blinded retrospective review of 6 morphologic features in the thyroid FNA specimens was conducted. These review findings were then correlated with the histopathologic diagnosis (benign or malignant).

RESULTS:

Of the 76 cyst fluid only cases with subsequent thyroidectomy, 10 cases had an ipsilateral diagnosis of papillary carcinoma measuring ≥1.0 cm. There was no association found between the number or amount of acute inflammatory cells, blood, colloid, macrophages, and pigmented macrophages and the histologic outcome. In only 4 of the 10 cases with a malignant outcome was the specimen assessed as being truly inadequate on retrospective review, and in 1 of these cases, the cytology was suggestive of malignancy.

CONCLUSIONS:

The only cytomorphologic characteristic found to be predictive of subsequent malignancy in cyst fluid only cases was the presence of follicular epithelium with atypical or suspicious features. Therefore, cases containing atypical epithelial cells should not be categorized as nondiagnostic or cyst fluid only, but rather diagnosed as atypical or suspicious.
