Description

General description

Acenaphthene is a polycyclic aromatic hydrocarbon used as a building block in the synthesis of polymers and resins.
Bacterial oxidation of acenaphthene by Beijerinckia sp. and Beijerinckia sp. strain B8/36 has been reported. Acenapthene forms 1:1:1 inclusion compound by complexing with inclusion compound of β-cyclodextrin and alcohol. Kinetics of the atmospherically important gas-phase reactions of acenaphthene with OH and NO₃ radicals, O₃ and N₂O₅ has been investigated at 296 ± 2K.

Application

• Optimization of Acenaphthene Production: A research article demonstrated the use of high-efficiency HILIC capillary columns for slurry packing at 2100 bar, showcasing an advanced technique that could optimize the synthesis and purification of complex polycyclic aromatic hydrocarbons like acenaphthene, essential for enhancing productivity and purity in chemical processes (Anderson et al., 2024).


• Environmental Impact Assessment: A study investigated the relationship between polycyclic aromatic hydrocarbons (PAHs) and reactive oxygen species in PM2.5 emissions, providing a critical evaluation of the environmental impacts of compounds like acenaphthene in industrial regions, thus informing pollution control and environmental safety strategies (Xu et al., 2024).


• Advances in Organic Semiconductor Materials: Research focused on the synthesis and properties of pyrene-bridged acenaphthenes, contributing to the development of novel organic semiconductor materials, which are crucial for electronic and photonic applications, thus broadening the utility of acenaphthene in high-tech industries (Polkaehn et al., 2023).


• Bioassays for Organic Pollutants: Researchers developed bioassays for organic pollutants, including acenaphthene, using chemical activity-based loading of artificial sediments. This approach offers a new method to assess ecological risks associated with organic contaminants, while also optimizing the derivation of predicted no-effect concentrations (PNECs) for polycyclic aromatic hydrocarbons, critical for regulatory compliance and environmental health.
