Application

The purpose of Anthracene Zone Refined (number of passes:30) is to serve as a highly purified form of anthracene, a colorless to pale yellow crystalline solid known for its bluish fluorescence. This meticulously refined product, achieving purification through thirty passes, is particularly valuable for applications requiring high purity anthracene. It is primarily used in the production of dyes, plastics, and pesticides, and is integral to the creation of scintillation counter crystals, which are essential for detecting and counting flashes of light over time. The compound anthracene, found in the heavy and green-oil fractions of crude oil, is obtained by fractional crystallization, with its benzene-like structure consisting of three fused six-membered rings typical of aromatic compounds. This specialized refinement, reaching a significant level of crystallinity, also underscores its role in advanced research and development fields that demand strictly controlled chemical integrity.
