In 2008,Rapid Communications in Mass Spectrometry included an article by Barrero-Moreno, Josefa M.; Tirendi, Salvatore; Reniero, Fabiano; Giordano, Giuseppe; Kotzias, Dimitrios. Recommanded Product: 2,3-Diisobutyl-2,3-dimethylsuccinonitrile. The article was titled 《Identification of 2,3-dimethyl-2,3-diisobutyl succinonitrile in laser printer emissions》. The information in the text is summarized as follows:
2,3-Dimethyl-2,3-diisobutyl succinonitrile was identified as the main volatile organic compound (>90%) emitted from laser printers during printing. Experiments were conducted in a large environmental chamber (30 m3) where printers were placed and working to simulate actual office setting conditions. Air, collected on Tenax TA adsorbent cartridges near the printers, was analyzed by thermal desorption gas chromatog.-mass spectrometry. Determined compounds are discussed. Addnl. data obtained by NMR, Fourier transform IR spectroscopy, and liquid chromatog.-tandem mass spectrometry (LC-MS/MS) supported the proposed structure (having no reported Chem. Abstracts Service number), as 2,3-dimethyl-2,3-diisobutyl succinonitrile. This compound is a byproduct of the thermal decomposition of 2,2′-azobis(2,4-di-Me valeronitrile), a com. available free radical polymerization initiator used in polymerization processes during toner manufacturing By headspace GC/MS, 15 toners used in black and white and color printers were examined; 6 contained 2,3-dimethyl-2,3-diisobutyl succinonitrile, which was also detected in processed paper. The experimental process involved the reaction of 2,3-Diisobutyl-2,3-dimethylsuccinonitrile(cas: 80822-82-8Recommanded Product: 2,3-Diisobutyl-2,3-dimethylsuccinonitrile)
2,3-Diisobutyl-2,3-dimethylsuccinonitrile(cas: 80822-82-8) is a member of nitriles. Nitriles have been reduced to amines by many methods, especially by catalytic hydrogenation and by metal hydrides. Aliphatic and aromatic nitriles have also been reduced to nitro derivatives using hydrazinium monoformate in the presence of Raney-nickel.Recommanded Product: 2,3-Diisobutyl-2,3-dimethylsuccinonitrile
