Synthesis of a rare‐metal adsorbing polymer by three‐component polyaddition of diamines, carbon disulfide, and diacrylates in an aqueous/organic biphasic medium

15-12-2010 | Nagai, Daisuke; Imazeki, Tsutomu; Morinaga, Hisatoyo; Nakabayashi, Hirotoshi, Journal of Polymer Science Part A: Polymer Chemistry, 2010

Abstract Three‐component polyaddition of diamines, carbon disulfide (CS2), and diacrylates in an aqueous/organic biphasic medium produced a polymer capable of adsorbing rare metals. By using a 1:1 mixture of toluene and H2O, the polyaddition reaction of 1,3‐di‐4‐piperidylpropane (1), CS2, and ...


Rapid monitoring of sulfur mustard degradation in solution by headspace solid‐phase microextraction sampling and gas chromatography mass spectrometry

15-12-2010 | Creek, Jo‐Anne M.; McAnoy, Andrew M.; Brinkworth, Craig S., Rapid Communications in Mass Spectrometry, 2010

Abstract A method using headspace solid‐phase microextraction (HS‐SPME) followed by gas chromatography/mass spectrometry (GC/MS) analysis has been developed to gain insight into the degradation of the chemical warfare agent sulfur mustard in solution. Specifically, the described approach ...


Combustion Emissions from Refining Lower Quality Oil: What Is the Global Warming Potential?

13-12-2010 | Greg Karras, Environmental Science & Technology, 2010

The greenhouse gas emission intensity of refining lower quality petroleum was estimated from fuel combustion for energy used by operating plants to process crude oils of varying quality. Refinery crude feed, processing, yield, and fuel data from four regions accounting for 97% of U.S. refining ...


Synthesis, thermal behavior, and spectral properties of mixed-metal Cu(I)-VO(IV)-thiourea coordination polymers

10-12-2010 | Otilia Costisor, Mihaela Vlad, Viorel Sasca, Imre Labadi, Oana Carp, Wolfgang Linert, Monatshefte für Chemie / Chemical Monthly, 2010

Abstract The heterometallic complexes [Cu(VO)2(CSN2H4)3Cl(OH)4]·H2O, [Cu2(VO)2(CSN2H4)2(C2H3O2)2·(OH)4], and [Cu2(VO)3(CSN2H4)4(C2H3O2)4(OH)4] were prepared and characterized in terms of their molecular electrical conductivity, electronic and IR spectra, and thermal behavior. A polymeric ...


Sulfur removal from coal‐derived syngas: thermodynamic considerations and review

10-12-2010 | Dolan, Michael D.; Ilyushechkin, Alex Y.; McLennan, Keith G.; Sharma, Sunil. D., Asia-Pacific Journal of Chemical Engineering, 2010

Abstract Current research into desulfurization sorbents for coal gasification is aimed at maximizing sorption capacity, kinetics and attrition resistance, while minimizing cost and volatility. Isolating the chemical aspects of desulfurization sorbent performance, however, is difficult because ...

Organic Letters DOI: 10.1021/ol102565b


High-Pressure Solubility Data for Palm Oil−SF6 and Coconut Oil−SF6 Systems

09-12-2010 | Željko Knez; Ljiljana Ilić; Mojca Škerget; Petra Kotnik, Journal of Chemical & Engineering Data, 2010

High-pressure vapor−liquid-phase equilibria (P−T−x−y) for the palm oil−SF6 and coconut oil−SF6 systems were investigated at temperatures of (313.15 and 333.15) K in the pressure range from (1 to 50) MPa. The phase behavior of two vegetable oils in sulfur hexafluoride (SF6) was studied using an ...


Solvothermal Syntheses and Crystal Structures of Neodymium Thiostannates [Nd(dien)3]2[(Sn2S6)Cl2] and [Nd(dien)3]2[(Sn2S6)(SH)2]

08-12-2010 | Xin-hua Lu, Jing-jing Liang, Jing Zhao, Yong Zhang, Ding-xian Jia, Journal of Chemical Crystallography, 2010

Abstract Two neodymium thiostannates [Nd(dien)3]2[(Sn2S6)Cl2] (1) and [Nd(dien)3]2[(Sn2S6)(SH)2] (2) (dien = diethylenetriamine) were synthesized by the reaction of tin and sulfur in the presence of NdCl3 and Nd2O3, respectively under solvothermal conditions. Compounds 1 and 2 crystallize in ...


On rheology, cure kinetics and chemorheology of gum rubbers

08-12-2010 | Arpita Mitra, Arkady I. Leonov, Polymer Science Series A, 2010

The paper presents an experimentally supported modeling approach, which describes the rheology, detailed cure kinetics, and chemorheology of a gum elastomer in course of sulfur accelerated vulcanization. Changes in the rheology during cure reaction are correlated with degree of cross-linking, ...


Addition of sulfur radicals to fullerenes

07-12-2010 | Denis, Pablo A.; Iribarne, Federico, International Journal of Quantum Chemistry, 2010

Abstract The addition of oxygen‐centered radicals to fullerenes has been intensively studied due to their role in cell protection against against hydrogen peroxide induced oxidative damage. However, the analogous reaction of sulfur‐centered radicals has been largely overlooked. Herein, we ...
