What Is Methylene?
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.
Uses of Methylenes
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.
Properties of Methylenes
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.
Other Information on Methylenes
