Résumé :

Abstract A method for the simultaneous determination of methyldibromo glutaronitrile, bronopol, and broni-dox in cosmetics, based on liquid chromatography with electrochemical detection, is described. The method is suitable for both aqueous products and emulsions. The detection limit is better than 0.002% for all analytes. Recoveries from an emulsion, spiked to concentrations of 0.03% of the analytes, were 100.4% for bronopol [relative standard deviation (RSD), 0.43%], 97.1% for bronidox (RSD, 0.83%), and 98.4% for methyldibromo glutaronitrile (RSD, 1.7%). Repeatabilities were calculated from 10 replicate analyses of commercial samples. The repeatability for bronopol from an emulsion containing 0.047% bronopol was 0.0027% (RSD, 1.99%); for bronidox from a lotion containing 0.027% bronidox, 0.0014% (RSD, 1.86%); and for methyldibromo glutaronitrile from an emulsion containing 0.031% methyldibromo glutaronitrile, 0.0019% (RSD, 2.16%). A ruggedness test showed that sample amount influenced the results for all 3 analytes. The results obtained for bronidox also depended on detection parameters and composition of extraction solvent. The method was applied to 138 cosmetic products and performed trouble free during these analyses. Bronopol was found in 14 samples, and bronidox was found in 4 samples, including a baby hair lotion, in which it is prohibited. Methyldibromo glutaronitrile was present in 27 samples, including creams, lotions, and sun protection cosmetics.

Résumé :

Context. Nitriles constitute almost 15% of the molecules observed in the interstellar medium (ISM), surprisingly only two dinitriles have been detected in the ISM so far. The lack of astronomical detections for dinitriles may be partly explained by the absence of laboratory rotational spectroscopic data. Aims. Our goal is to investigate the rotational spectrum of glutaronitrile, N≡C−CH2−CH2−CH2−C≡N, in order to allow its possible detection in the ISM. Methods. The rotational spectrum of glutaronitrile was measured using two different experimental setups. A Fourier transform microwave spectrometer was employed to observe the supersonic jet rotational spectrum of glutaronitrile between 6 and 20 GHz. In addition, the mmW spectrum was observed in the frequency range 72−116.5 GHz using a broadband millimetre-wave spectrometer based on radio astronomy receivers with fast Fourier transform backends. The spectral searches were supported by high-level ab initio calculations. Results. A total of 111 rotational transitions with maximum values of J and Ka quantum numbers 54 and 18, respectively, were measured for the gg conformer of glutaronitrile. The analysis allowed us to accurately determine the rotational, nuclear quadrupole coupling, quartic and sextic centrifugal distortion constants. These rotational parameters were employed to search for glutaronitrile in the cold and warm molecular clouds Orion KL, Sgr B2(N), B1-b and TMC-1, using the spectral surveys captured by IRAM 30 m at 3 mm. Glutaronitrile was not detected, and the upper limits’ column densities were derived. Those are a factor of 1.5 and 5 lower than those obtained for the total column densities of the analogous succinonitrile in Orion KL and Sgr B2, respectively.

Résumé :

An electrolyte, N,N′-1-ethyl-4-butyl, triethylene diamine hexafluorophosphate dissolved in glutaronitrile, was developed and investigated in a symmetrical supercapacitor using activated carbon as electrodes (active carbon/active carbon). The electrochemical erformance of the supercapacitor was examined using ac impedance and constant current charging/discharging tests. According to the results, its singleanode speciﬁc capacitance could reach 324.7 Fg−1. The supercapacitor also has better capacitance characteristics.

Résumé :

Feng Li of the Nanjing University of Science and Technology devised (Chem. Commun. 2014, 50, 8303) a combination of reagents that directly converted the alcohol 1 to the protected amine 2. Yong-Sheng Bao and Bao Zhaorigetu of Inner Mongolia Normal University selectively (J. Org. Chem. 2014, 79, 6715) demethylated the tertiary amine 4, leading to the amide 5. Christopher W. Bielawski of the University of Texas developed (Chem. Eur. J. 2014, 20, 13487) the reagent 7 for the conversion of an alcohol 6 to the bromide 8. The diiodo analogue of 7 also worked well. Ross Denton of the University of Nottingham showed (Chem. Commun. 2014, 50, 7340) that the reagent 10 efficiently mediated the Mitsunobu coupling of 9 with benzoic acid to give 11. The other product of the reaction, Ph₃ P=O, could be converted back to 10. Silas P. Cook of Indiana University established (J. Am. Chem. Soc. 2014, 136, 9521) conditions for the selective conversion of the bromide 12 to the boronate 13. Gwilherm Evano of the Université Libre de Bruxelles converted (Chem. Commun. 2014, 50, 11907) the alkenyl iodide 14 to the nitrile 15 using acetone cyanohydrin as the nitrile anion source. Seth B. Herzon of Yale University developed (Angew. Chem. Int. Ed. 2014, 53, 7892) an improved Ru catalyst for the hydration of a terminal alkyne 16 to the aldehyde 17. Clément Mazet of the University of Geneva used (Chem. Commun. 2014, 50, 10592) an Ir catalyst for the isomerization of a 2,2-disubstituted epoxide 18 to the aldehyde 19. Laurent El Kaïm of the Ecole Polytechnique, Laurence Grimaud of UMPC, and Roland Jacquot and Philippe Marion of Solvay showed (Synthesis 2014, 46, 1802) that in the presence of glutaronitrile 21, AlCl₃ was an effective catalyst for the conversion of an acid 20 to the nitrile 22. Yi-Si Feng and Hua-Jian Xu of the Hefei University of Technology found (Org. Lett. 2014, 16, 4586) that a carboxylic acid 23 could be coupled with diphenyl disulfide under decarboxylating conditions, leading to the sulfide 24. Kenneth M. Doll of USDA Peoria observed (ACS Catal. 2014, 4, 3517) that decarboxylation of the unsaturated carboxylic acid 25 with a Ru catalyst delivered the alkene 26 as a mixture of regioisomers.
