Methylene, a colorless liquid with a sweet aromatic odor, is known chemically as an aromatic organic compound with the formula C9H12. It's recognized for its structure where three hydrogens in the benzene ring are substituted by methyl groups. Discovered by Robert Kane in 1837, it's a key component found in coal tar and serves as a precursor for numerous chemicals.
Employed for its solvent properties in organic synthesis and semiconductor wafer etching, methylene is pivotal in synthesizing dyes, pigments, and pharmaceuticals. It's instrumental in forming fullerene nanowires and specific aromatic compounds through various chemical reactions.
A flammable liquid, methylene freezes at -44.8°C, boils at 164.7°C, and has a flash point of 50°C. It's a significant volatile organic compound in urban environments, contributing to atmospheric chemistry dynamics.
Produced via acetone distillation or propine trimerization in sulfuric acid's presence, methylene's synthesis also involves the transalkylation of xylene catalyzed by solid acids.
Methylene undergoes various reactions, including oxidation to trimethynic acid, aldehyde formation with manganese dioxide, and bromination to mesityl bromide.
Regulated under several laws for its handling and environmental impact, methylene requires careful usage and disposal practices to ensure safety and compliance.
Emphasizing safety, handling, and storage precautions includes using protective gear, avoiding ignition sources, and ensuring proper ventilation to minimize health risks.
