General description

1-Methylnaphthalene occurs in Chinese raw spirits, brown millet, milled millet and millet bran. This volatile organic compound (VOC) is also found in the diesel engine exhaust gas and in the manures of cow, hog and chicken.

Application


  • Viscosities and Densities of Binary and Ternary Mixtures of Aliphatic and Polyaromatic Hydrocarbons: Pyrene +1-Methylnaphthalene + Dodecane at T = (293.15 to 343.15) K. Experiment and Modeling.: This research presents experimental data and modeling of the viscosities and densities of mixtures involving 1-methylnaphthalene, providing valuable data for industrial applications and theoretical studies in chemical engineering (Tenorio et al., 2024).

  • Chemical Composition and Optical Properties of Secondary Organic Aerosol from Photooxidation of Volatile Organic Compound Mixtures.: Investigates the secondary organic aerosols produced from photooxidation of volatile organic compounds including 1-methylnaphthalene, highlighting their optical properties and implications for air quality and climate modeling (Cui et al., 2024).

  • Oxidation 1-methyl naphthalene based on the synergy of environmentally persistent free radicals (EPFRs) and PAHs in particulate matter (PM) surface.: This study explores the oxidative mechanisms of 1-methyl naphthalene on particulate matter surfaces, facilitated by environmentally persistent free radicals. The findings contribute to the understanding of air pollution chemistry and environmental degradation processes (Ghimire et al., 2023).
