应用


  • OH-initiated Degradation of 1,2,4,5-Tetramethylbenzene: Research on the environmental behavior of 1,2,4,5-tetramethylbenzene highlights its degradation mechanisms and kinetics when exposed to OH radicals, underscoring its impact on air quality and potential ecological risks. This study is essential for environmental monitoring and management strategies involving aromatic hydrocarbons (Zhao et al., 2022).

  • Low-Temperature Curing of Liquid Polybutadiene Using Nitrile Oxide: This study explores the application of 1,2,4,5-tetramethylbenzene in enhancing the curing process of liquid polybutadiene at low temperatures, illustrating its role as an effective solvent in the synthesis of polymers. Such applications are crucial for the development of advanced materials with improved performance characteristics (Li and Wang, 2022).

  • Hygroscopic Properties of Calibration Standards for NMR Spectroscopy: 1,2,4,5-Tetramethylbenzene′s utility in nuclear magnetic resonance (NMR) spectroscopy as a calibration standard is detailed, focusing on its hygroscopic tendencies which affect the accuracy of quantitative analyses. This is vital for ensuring the reliability and precision of chemical measurements in research and industrial applications (Suiter and Widegren, 2021).

  • Novel Sampling Strategy for Alive Animal Volatolome Extraction: The compound′s use in gas chromatography-mass spectrometry (GC-MS) based untargeted metabolomics for identifying pheromones in animal studies showcases its applicability in complex biological analyses, which is significant for advancements in veterinary and behavioral sciences (Lacalle-Bergeron et al., 2021).

  • Microbial Degradation of Aromatic Hydrocarbons: The research on microbial degradation pathways of mobile aromatic hydrocarbons including 1,2,4,5-tetramethylbenzene provides insights into environmental remediation techniques. This is especially relevant for the biodegradation processes necessary for reducing pollution from dense non-aqueous phase liquids (DNAPLs) (Van Leeuwen et al., 2020).

One- (1-D) and two-dimensional (2-D) carbon-13 NMR exchange measurements in powder samples of isotopically normal durene under magic angle spinning (MAS) are reported. The experiments include rotor synchronized 2-D exchange (RS2DE), 1-D magnetization transfer (MT) and time reverse ODESSA (tr-ODESSA).

A series of N-[(2,3,4,6-tetramethylbenzoyl)alkyl]imidazoles and of N-([beta-(2,3,5,6-tetramethylphenyl)-beta-hydroxy]ethyl)imidazoles has been synthesized. All compounds were tested in mice for anticonvulsant activity against electroshock and pentylenetetrazole convulsions. These durene-derivatives showed good activity, whereas the corresponding benzene-derivatives were inactive.
